Section 1: General Information
1.0 Introduction
This section provides the general information for the Teledyne Paradise Datacom
Compact Rack Mount (CRM) Series Solid State Power Amplifier (SSPA) Chassis. This
includes a description of the unit and safety precautions for operation of the unit.
1.1 Description
The Teledyne Paradise Datacom Compact Rack Mount (CRM) Series SSPA Chassis
was specially designed to accommodate applications where rack space is at a
premium. At only 3RU in height and a depth of 24 inches (610 mm) the CRM Series
SSPA Chassis is perfect for use in Satellite News Gathering or flyaway applications.
A rich feature set has been maintained, despite the small size of the chassis. For field
maintainability, this chassis features:
• Front and rear panel removable fan trays
• Front panel removable power supply modules
• Rear panel removable controller card assembly
• Front panel RF output sample port
This chassis includes a wide array of standard interfaces:
• Front Panel Local Interface and Status Indicators
• RS232/RS485 (4-wire) Serial Communication (with either Windows-
based M&C or third-party M&C drivers available)
• Ethernet Port (SNMP, UDP Serial Programming, Web Browser Interface)
• Parallel I/O (Form C Contact Outputs, Opto Isolated Inputs)
Optional interfaces include:
• Remote Control Panel (using the optional 1RU RCP2-1000-RM)
The chassis’ microprocessor monitors various voltages, currents and temperatures
within the unit for a full fault analysis. The user also may select additional faults related
to the RF output level, an optional reflected RF power level and operating temperature.
An internal attenuator allows up to 20.0 dB of attenuation to be applied to the RF
signal. Temperature compensation limits the amplifier’s output response from varying
significantly over the operating temperature. Also, the system contains input and
output sample ports.

with this unit. To ensure safe operation, the user must follow the information, cautions
and warnings provided in this manual as well as the warning labels placed on the unit
itself.
12 205356 REV T 3 RU SSPA Chassis Operations Manual
1.7.1 High Voltage Hazards
High Voltage, for the purpose of this section, is any voltage in excess of 30V. Voltages
above this value can be hazardous and even lethal under certain circumstances. Care
should be taken when working with devices that operate at high voltage.
• All probes and tools that contact the equipment
should be properly insulated to prevent the operator
from coming in contact with the voltage.
• The work area should be secure and free from nonessential items.
• Operators should never work alone on high voltage
devices. There should always be another person present in the same work area to assist in the event of
an emergency.
• Operators should be familiar with procedures to employ in the event of an
emergency, i.e., remove all power, CPR, etc.
• An AC powered unit will have 115 VAC or 230 VAC entering through the
AC power connector. Caution is required when working near this connector, the AC circuit breaker, or the internal power supply.
1.7.2 High Current Hazards
Many high power devices are capable of producing large
surges of current. This is true at all voltages, but needs to
be emphasized for low voltage devices. Low voltage
devices provide security from high voltage hazards, but also
require higher current to provide the same power. High
current can cause severe injury from burns and explosion.
The following precautions should be taken on devices
capable of discharging high current:
• Remove all conductive personal items (rings, watches, medals, etc.)
• The work area should be secure and free of non-essential items.
• Wear safety glasses and protective clothing.
• Operators should never work alone on high risk devices. There should
always be another person present in the same area to assist in the event
of an emergency.
• Operators should be familiar with procedures to employ in the event of an
emergency, i.e., remove all power, CPR, etc.
Large DC currents are generated to operate the RF Module inside of the enclosure.
Extreme caution is required when the enclosure is open and the amplifier is operating.
Do not touch any of the connections on the RF modules when the amplifier is operat-
ing. Current in excess of 60 Amperes may exist on any one connector.
3 RU SSPA Chassis Operations Manual 205356 REV T 13
1.7.3 RF Transmission Hazards
RF transmissions at high power levels may cause eyesight damage and skin burns.
Prolonged exposure to high levels of RF energy has been linked to a variety of health
issues. Please use the following precautions with high levels of RF power.
• Always terminate the RF input and output connector
prior to applying prime AC input power.
• Never look directly into the RF output waveguide
• Maintain a suitable distance from the source of the
transmission such that the power density is below
recommended guidelines in ANSI/IEEE C95.1. The
power density specified in ANSI/IEEE C95.1-1992 is
10 mW/cm2. These requirements adhere to OSHA
Standard 1910.97.
• When a safe distance is not practical, RF shielding should be used to
achieve the recommended power density levels.
1.7.4 Electrical Discharge Hazards
An electric spark can not only create ESD reliability problems, it can also cause serious
safety hazards. The following precautions should be followed when there is a risk of
electrical discharge:
• Follow all ESD guidelines
• Remove all flammable material and solvents from the
area.
• All probes and tools that contact the equipment
should be properly insulated to prevent electrical discharge.
• The work area should be secure and free from nonessential items.
• Operators should never work alone on hazardous equipment. There
should always be another person present in the same work area to assist
in the event of an emergency.
• Operators should be familiar with procedures to employ in the event of an
emergency, i.e., remove all power, CPR, etc.
1.7.5 High Potential for Waveguide Arcing
As with all systems which utilize high power signals within
waveguide, the potential exists for an electric arc to form.
To minimize this risk, Teledyne Paradise Datacom requires all waveguide be pressurized and dehydrated.
14 205356 REV T 3 RU SSPA Chassis Operations Manual
1.8 Waveguide Pressurization and Dehydration
When working with high power amplifier systems that operate into waveguide, the inadvertent creation of arcs is always a concern. An arc in waveguide is the air discharge
breakdown due to the ionization of the air molecules by electrons. This breakdown in
waveguide occurs when the rate of electron production becomes greater than the loss
of electrons to diffusion to the surrounding walls.
It is extremely difficult to precisely predict the power levels at which the breakdown occurs. It is dependent on a variety of factors but the primary factors are:
• Waveguide temperature and atmospheric pressure
• Components in the Waveguide Transmission System such as: Flanges,
Bends, Tees, Combiners, Filters, Isolators, etc.
• Load VSWR presented to the amplifier.
When operating such a high power amplifier system it is imperative that the waveguide
transmission system be dehydrated and pressurized. Operation with an automatic air
dehydrator will provide dry pressurized air to ensure that condensation cannot form in
the waveguide. Also the higher the pressure that can be maintained in the waveguide;
the higher the power handling is in the waveguide system. Most commonly available
air dehydrators are capable of providing pressures of 0.5 to 7.0 psig (25-362 mmHg).
At low power levels (uniform field distribution), low pressure can give good results. For
non-uniform conditions, highly localized breakdown can occur. In this case the waveguide system will require much higher pressure. This occurs with bends, waveguide
flange joints. If line currents flow across a small gap introduced by poor tolerances,
flange mismatch, poorly soldered bends, field strengths in excess of that in the main
line can occur in the gap. Pressurization with air or high dielectric gases can increase
the power handling by factors of 10 to 100.
In High Power Amplifier systems an arc will travel from where it is ignited back to the
amplifier. Typical arc travel speed is on the order of 20 ft/sec. Increasing the waveguide pressure can reduce the speed of arc travel. It is difficult to get an accurate calculation of the amount of pressurization needed, but it is a good practice to get as
much pressure as your system can handle. All high power systems that meet the crite-
ria of Table 1-1 are pressure tested at the factory to 1.5 psig. As a guide we recommend using the power levels in Table 1-1 as the threshold levels where special atten-
tion should be given to dehydration and the overall simplification of waveguide system
design.
3 RU SSPA Chassis Operations Manual 205356 REV T 15
Table 1-1: Recommended Output Power Thresholds
for Waveguide System Pressurization
Satcom Band Frequency Range Amplifier Output Power Waveguide
S Band 1.7-2.6 GHz > 10 kW WR430
C-Band 5.7 - 6.7 GHz > 2 kW WR137
X-Band 7.9-8.4 GHz > 1kW WR112
Ku-Band 13.75-14.5 GHz > 500W WR75
Ka-Band 27-31 GHz > 100W WR28
It is a common misconception to look up the maximum theoretical power handling of a
particular type of waveguide and assume that this is the maximum power handling.
This may be the case for a straight waveguide tube with ideal terminations but these
values must be significantly de-rated in practical systems. Phase combined amplifier
systems can be particularly sensitive to the potential for waveguide arcing. This is due
to the numerous bends, magic tees, multiple waveguide flange joints, and other wave-
guide components. Table 1-2 shows the power handling capability of some popular
waveguide components normalized to the waveguide power rating. From this table, we
can see how a practical waveguide system’s power handling will de-rate significantly.
Table 1-2: Relative De-rating of Popular Waveguide
Components Relative to Straight Waveguide
Waveguide Component Relative Power Rating
H Plane Bend 0.6 to 0.9
E Plane Bend 0.97
90o Twist 0.8 to 0.9
Magic Tee 0.80
E-Plane Tee 0.06
H-Plane Tee 0.80
Cross Guide Coupler 0.21
Most waveguide systems have many of these components integrated before reaching
the antenna feed. It is not uncommon for a Satcom waveguide network to de-rate to
5% of the straight waveguide power rating.
The load VSWR also has an impact on the breakdown threshold in waveguide networks. Standing waves degrade the power handling of any transmission line network.
The graph of Figure 1-1 shows the rapid degradation of waveguide breakdown vs.
load VSWR. The chart shows that for a 2.0:1 load VSWR, the breakdown potential will
be half of what it would be with a perfectly matched load. This can degrade even more
when high Q elements such as band pass filters are included in the waveguide network.

There are many factors to consider with high power amplifier systems in terms of the
output waveguide network. Especially when using HPA systems with output power
levels of Table 1-1, it is imperative to ensure that the output waveguide network is
pristinely clean and dry. An appropriate dehydrator should be used with capability of
achieving adequate pressure for the system’s output power. Take extra precaution to
make sure that any waveguide flange joints that are not already in place at the factory
are properly cleaned, gasket fitted, and aligned. A properly designed and maintained
waveguide network will ensure that no arcing can be supported and will provide many
years of amplifier service life.

The prime power connector, J10, provides universal AC input by using auto-sensing
power supplies. The AC input can operate over a range of 90-265 VAC, at 47 to 63 Hz.
The power supply is also power factor corrected, enabling the unit to achieve a power
factor greater than 0.93. An IEC 6100-3300 (F) connector is used and a connecting
cable is included with the amplifier.
3 RU SSPA Chassis Operations Manual 205356 REV T 21
2.1.2.2 DC Input with N+1 Redundant External Power Supply (J10) (Option)
The combination of a separate +12 VDC output, fully redundant power supply is an
excellent means of obtaining the ultimate system reliability. The power supply is an
N+1 redundant configuration, meaning that a failure of a single power supply module
will not take the amplifier off the air.
In addition, the power supply modules are removable from the front panel while in
operation. There is never a need to remove the power supply from the equipment bay.
Weighing only 9 lbs. (4 kg) and occupying only 1 rack unit of cabinet space, the
redundant power supply chassis is an excellent companion to the SSPA chassis.
Power connection to the SSPA is via quick-snap connectors to the input power
bulkhead at Port J10.
Each power supply has a single phase, universal AC input ranging from 90-265 VAC,
47-63 Hz and is power factor corrected to 0.99. Depending on the power requirements
of the SSPA, the power supply is configured with up to four (4) 1200W hot-swappable
modules, each of which weigh approximately 5 lbs. (2.3 kg).
Figure 2-3 shows a 3RU SSPA chassis with a N+1 Redundant External Power Supply.
Note the blanking panels in place of the power supplies normally integral to the SSPA
chassis.
Figure 2-3: 3RU SSPA Chassis with 1RU N+1 Redundant Power Supply
It should be noted that if a power module is removed from the chassis during normal
operation, it will trigger a power supply fault. The operator must wait 30 seconds before
re-inserting the module or the fault will not clear.
The power supply chassis has a dual feed AC architecture. Power module slots 0 & 1
are supplied via AC Feed 1 and power module slots 2 & 3 are supplied via AC Feed 2.
22 205356 REV T 3 RU SSPA Chassis Operations Manual
The AC connections on the shelf are made via rear accessed
compression style terminal blocks. See Figure 2-4. Connect
the first line/hot to L1, the second line or neutral to L2/N and
the AC ground to GND. These terminal blocks will accept up
to a maximum of 10 AWG wire, and should be torqued to
6 in-lbs.
The power supply is connected to the SSPA via an alarm
cable, part number L205676-1, supplied with the unit. This
cable connects between the Alarm port of the power supply
and the PS M&C Port (J12) of the SSPA. See Figure 2-5.
Figure 2-4:
Terminal block
Each power supply module has an alarm output. For logic reporting purposes, the
alarm outputs for power supply modules 1 and 2 are linked, as are those for power
supply modules 3 and 4. The power supply alarms are monitored by the SSPA Chassis
monitor and control system. This provides local and remote alarm reporting in the
event of a power supply module failure.

supplied cable L206406-1. This cable also contains a current sharing line between the
two power supply chassis.
3 RU SSPA Chassis Operations Manual 205356 REV T 23
The power supply alarms may be monitored via the SSPA Chassis front panel menu.
See Section 2.2.1.2. In the event that one or more power supply modules enter a fault
condition, the SSPA Chassis will report a major (Summary) fault and will mute until the
fault conditions are cleared.
2.1.2.3 R3 Input Port (J1) [Type N (F)]
The type N female connector on the right side of the rear panel is used as the RF
input.
2.1.2.4 RF Output Port (J2) [Band specific]

2.2.1.6 Sys Info Page 6
This page shows the status of the HPA’s internal power supplies.
• PS1(V) — Main power supply 1 output voltage with resolution of 0.1V.
Normal output voltage for GaAs amplifiers is in the range of 11 to 13 V;
The voltage range for GaN amplifiers depends on the frequency band of
the unit. Typical GaN SSPA power supply ranges are:
○ L– and S-Band SSPAs: 40 to 50 VDC;
○ C-Band SSPAs: 24 to 28 VDC;
○ X-Band SSPAs: 20 to 26 VDC;
○ Ku-Band SSPAs: 20 to 28 VDC;
○ Ka-Band SSPAs: 20 to 24 VDC.
• PS2(V) — Main power supply 2 output voltage. See above.
• Boost1(V) — Booster power supply 1 output voltage with resolution of
0.1V. Normal range 24 to 30 V (typical 28V);
• Boost2(V) — Booster power supply 2 output voltage.
• DC (A) — Total DC current draw by RF modules from main power sup-
ply. Value varies depending on the power level of the HPA. If the HPA is
muted, current normally drops to within the 0 to 5 A range.
32 205356 REV T 3 RU SSPA Chassis Operations Manual
2.2.1.7 Sys Info Page 7
This page shows RF module related faults and conditions.
• Regulator — RF module regulator low voltage fault. Values: “FAULT!” or
“Normal”;
• DC Current — Low DC current fault. Values: “FAULT!” or “Normal”;
• Temperature — High temperature fault. Values: “FAULT!” or “Normal”.
• Temp.(C) — Internal RF module plate temperature in Celsius. In multi-
module units, only the hottest module baseplate temperature is displayed.
2.2.1.8 Sys Info Page 8
This page shows individual RF module states in multi-module HPAs.
• Mod# & PreAmp — Mod1 to Mod4 represent the overall state of the rele-
vant RF Power modules. If the amplifier is equipped with a separate preamplifier module, the “PreAmp” value will represent the overall state of
the pre-amplifier. Under normal operation, the value will read “Normal”.
If a unique module does not exist in the HPA configuration, the value
shows “N/A” (not available). Each value represents the summary fault
state of an individual RF module, which includes the Voltage, Current and
Temperature state as well as the quality of data connection with module.
For a module or pre-amp exhibiting a fault condition, the value will read
“FAULT!”.
If the HPA controller card cannot reliably communicate with an SSPA
module, that module will be declared faulted. This type of fault will not affect the overall summary fault state, because the controller card has the
ability to track RF module faults independently. When an existing module
or pre-amp is present in the current HPA configuration, but fails to respond to control board status queries, “ComErr” (Communication Error)
will be displayed.
• PSModFlts — For amplifiers utilizing an external N+1 power supply, this
value indicates the number of detected N+1 PS module faults. For units
with an internal power supply, this value reads “000” and should be ignored. Check PS1 and PS2 Voltage readings to assess the state of an
internal power supply.
3 RU SSPA Chassis Operations Manual 205356 REV T 33
2.2.1.9 Sys Info Page 9 (version 6.00)
This page shows various miscellaneous operation parameters.
• Chssy Temp — Chassis temperature reading measured by the control
board. Since the control board is typically located at rear of the chassis,
this reading correlates with the exhaust air temperature;
• RecordHigh — The highest temperature detected over unit lifetime. This
value is updated each time a temperature higher than the current record
is detected. Value could be used for SSPAs problem troubleshooting.
Record data is factory reset only.
• BUC PS1(V) — This value represents the power supply voltage used for
biasing an optional BUC unit. Voltage could be used for detecting problems related to BUC operation. The SSPA does not have a specific alarm
threshold for this voltage. Normal reading for this parameter should be in
range of 15V– 16V.
• BUC PS2(V) — This value represents secondary BUC power supply volt-
ages. For a unit equipped with a single power supply this value shows “N/
A” (not available).
2.2.1.10 Sys Info Page 10 (version 6.00)
The page shows advanced fault analysis information and advanced N+1 operation features.
• MuteFault – This parameter allows the user to check the SSPA mute
condition. Possible values:
○ Clear — No present fault mute condition on SSPA unit. Mute/Unmute
function under full user control;
○ Set — One or more mute fault conditions present in the system. The
unit is forced to the Mute On condition.
• MFltCause — Parameter allows user to determine last detected Mute
fault condition. Possible values:
○ None — No detected Mute fault conditions;
○ AuxFlt — Mute fault condition triggered by a detected Auxiliary fault.
○ ExtM — Mute condition forced by external signal applied on the par-
allel port Mute input;
○ BUCFlt — Mute fault condition caused by a detected BUC fault;
○ PSFlt — The unit is forced to mute due to one or more failed N+1
power supply modules;
○ N+1Flt — N+1 configuration forced unit into a mute state due to an
internal summary fault condition;
• LastFault – This parameter shows information about the last detected
fault. The value is latched to the last fault occurrence. Use the Clear Fault
function to reset. Possible Values:

The SSPA will answer a request which comes only from the assigned IP
address. For firmware prior to version 6.00, set this address value to
0.0.0.0 or 255.255.255.255 to disable this feature.
Starting with version 6.00, the Lock IP address function has been updated to allow “Binding” and “Masking” functions. Binding" means that the
first datagram retrieved for this socket will bind to the source IP address
and port number. Once binding has been completed, the SSPA will answer to the bound IP source until the unit is restarted or reset. Without
binding, the socket accepts datagrams from all source IP addresses.
Address 0.0.0.0 allows all peers, but provides binding to first detected IP
source; Address 255.255.255.255 accepts all peers, without binding. If
Lock IP is a multicast address, then the amplifier will accept queries sent
from any IP address of multicast group;

2.2.2.6 N+1 Control (Floating Master Mode)
This menu allows the user to set parameters relating to Floating N+1 Master operation.
This feature allows having a single point of control for an N+1 system Master Module.
When enabled, this mode will switch the N+1 Master Module serial and IP address to a
dedicated floating Master IP and serial address.
Without this function, a faulted Master Module in an N+1 system delegates its control
privileges to another unit, which has a different serial and IP address.
With this feature activated, the Master serial and IP address are reassigned to the new
Master Module and the former master unit restores its normal communication parameters.
This mode of operation allows having single M&C connection point bonded to a known
IP and Serial address, regardless which module in the N+1 system assumes the role of
the Master Module. In this mode, the user could maintain a remote connection to a single Master unit. Simultaneous connections to other modules is optional.
If Floating Master mode is disabled, the N+1 Master unit responds to its unique IP and
serial address rather than to a dedicated master address. In this mode, simultaneous
connection to all N+1 unit in the system is the most desirable method of remote control
operation.
Floating Master mode could be used over both RS-485 and IP network. Communication over a RS-485 network requires the assignment of a unique Master serial address.
The module currently assigned as the Master Module will also respond to queries on
its own serial address.
When this mode is used over an IP network, certain factors need to be taken in account:
• The Master IP address must be a unique address, not used anywhere
else on the network;
• Since Floating Master mode is assumed, the Master Module will stop responding on its individual IP address and start responding on Master IP
address. When the Master Module assumes slave mode (and another
unit is assigned the Master privileges), the former Master unit responds
to its individual IP address;
• The Master address should be selected from same subnet mask and use
the same gateway address as the rest of the N+1 units in the system;
• During the switchover process from a unit’s normal IP address and Master address and back, the SSPA unit will execute a “gratuitous ARP” request to a network. The operator needs to make sure that the network
44 205356 REV T 3 RU SSPA Chassis Operations Manual
equipment connected to the system supports dynamic ARP tables which
could be updated by “gratuitous ARP”. Consult your network administrator for details;
• Floating Master mode needs to be disabled if network switches utilize
static ARP tables or if dynamic IP changes are forbidden.
Use of a dedicated serial Master address is optional, but desirable.
Menu selections include:
• 1.MasterIP Enable — This selection enables Floating Master mode;
• 2.MasterIP Disable — This selection disables Floating Master mode;
• 3.Serial Address — This selection allows the user to assign a unique
floating serial control address to the N+1 Master;
• 4.IP Address — This selection allows the user to assign a unique float-
ing IP address to the N+1 Master;
• 5.Info — This selection displays a informational menu regarding the
Floating N+1 Master mode. Includes the mode state (Enabled/Disabled),
the assigned serial address and assigned IP address.
• 6.Back — This selection opens the menu items listed in Section 2.2.2.6.

48 205356 REV T 3 RU SSPA Chassis Operations Manual
2.2.4.3 RF Switch Faults
Determines whether a switch fault should cause a major alarm and attempt to switch,
or simply show an alert on the front panel, the latter case considered a minor alarm.
• 1.Fault — This is the Major Alarm mode. Summary alarm on fault;
• 2.Alert — This is the Minor Alarm mode. No summary alarm on fault;
• 3.Switch Mute — In this mode, when the switch position changes, the
amplifier is momentarily muted during switchover to prevent arcing in the
waveguide;
• 4.Ignore — This setting ignores any RF Switch faults.
2.2.4.4 Fault Latch
Determines the alarm reporting condition. A latched alarm will remain indicated on the
front panel until the operator clears the alarm by pressing the Enter key. Unlatched
alarms will allow the summary alarm indicator to stop displaying the alarm condition if
the circumstance creating the alarm has been cleared or corrected.
2.2.4.5 Forward RF / Automatic Level Control
This menu allows the operator to choose whether to enable or disable a Forward RF
Fault Alarm, or to set Automatic Level Control.
2.2.4.5.1 Disable
This selection disables the Forward RF Fault Alarm function, as well as the Automatic
Level Control function. Selecting this item also unlatches any Forward RF fault conditions.
2.2.4.5.2 Low RF
When this menu item is selected, an alarm is triggered when the RF output power falls
below a threshold value, which is adjustable by the operator (see Section 2.2.4.5.5).
The operator may set the fault handling to trigger either a Major Fault (Fault) or Minor
Fault (Alarm).
• 1.Fault — When selected, a Major Fault condition (Summary Alarm) is
triggered when RF output power falls below the set threshold value;
• 2.Alarm — When selected, a Minor Fault condition is triggered when RF
output power falls below the set threshold value;
• 3.Back — This selection displays the menu listed in Section 2.2.4.5,
3 RU SSPA Chassis Operations Manual 205356 REV T 49
2.2.4.5.3 High RF
When this menu item is selected, an alarm is triggered when the RF output power rises
above a threshold value, which is adjustable by the operator (see Section 2.2.4.5.5).
This function is available in units with firmware version 6.14 and above.
The operator may set the fault handling to trigger either a Major Fault (Fault), Major
Fault with Mute, or Minor Fault (Alarm).
• 1.Fault (High RF) — When selected, a Major Fault condition (Summary
Alarm) is triggered when RF output power rises above the set threshold
value;
• 2.Fault + Mute — When selected, a Major Fault condition (Summary
Alarm) is triggered when RF output power rises above the set threshold
value, and the amplifier is placed in a mute state. To avoid output oscillations between the Mute and Unmute states, this fault condition will latch
itself and will not self-clear without operator intervention;
• 3.Alarm — When selected, a Minor Fault condition is triggered when RF
output power rises above the set threshold value;
• 4.Back — This selection displays the menu listed in Section 2.2.4.5,
There are several methods to clear detected High RF Fault Mute:
1. Select “Fault Clear” menu from front panel menu (see Section 2.2.1.1.1);
2. Apply “Fault Clear” signal from Parallel I/O port (see Table 2-3, pin 37);
3. Disable Forward RF fault (see Section 2.2.4.5.1).
2.2.4.5.4 ALC On (Automatic Level Control)
The Automatic Level Control function will take control of the amplifier’s attenuation settings to maintain the desired RF output power level and will not allow any attenuation
adjustments via the front panel. The ALC circuit will have the greatest ability to adjust
for positive and negative RF input level changes when the amplifier’s gain level is typically 65 dB.
By following the steps below, the optimum ALC RF input level can be set quickly.
1. Using the front panel menu, make sure the amplifier is not in ALC mode;
2. Set the amplifier attenuation level to 10 dB;
3. Apply a CW RF signal to the amplifier;
4. Use a power meter to measure the output power of the amplifier;
5. Adjust the RF input level until the desired output power level is achieved;
Follow the steps listed above to activate the ALC control. The ALC will take over the
control of the output level and maintain the RF output level set point.
50 205356 REV T 3 RU SSPA Chassis Operations Manual
The ALC has the ability to accurately control the RF output power over a 15 dB range
from P
. The ALC will operate over a 20 dB range, but the accuracy of the last 5 dB
sat
will suffer. For example, if the saturated power from the amplifier is 59 dBm, the lowest
accurate power setting during ALC control is 44 dBm.
If the output power set point is set outside the operational range of the ALC circuit, the
ALC will adjust the output power to the lowest possible level and set a minor fault on
the amplifier’s front panel.
Note: Automatic Level Control is inactive when the system is in N+1
operation.
2.2.4.5.5 Set Level
The operator may set the detected RF Output value used as the threshold for either a
High RF or Low RF fault condition. Valid values are 0 to 80 dBm, adjustable in 1 dBm
steps.
When the amplifier is set to detect High RF faults, if the detected RF Output rises
above the set value, a fault condition is triggered.
When the amplifier is set to detect Low RF faults, if the detected RF Output falls below
the set value, a fault condition is triggered.

3 RU SSPA Chassis Operations Manual 205356 REV T 53
2.2.5.6 Reset
Allows the user to reset the SSPA controller hardware to activate certain settings. For
example, when the IP Address is modified the SSPA must be reset for it to use the
new IP Address. Firmware version 6.00 allows multiple reset levels for SSPA unit:
• 1.I/O Card — Resets all hardware on the removable M&C card as well as
the embedded cards on all RF modules. The amplifier will be Muted during the reset process. Hence, reset will cause a momentary loss of RF
output. All communication links to remote M&C will be dropped until reset
process is complete. The amplifier will use currently selected communication parameters (IP address, baud rate, etc);
• 2.I/O Card & RFModule — Resets only embedded chips in all RF mod-
ules. I/O card remains operational and maintains communication link to
remote M&C. The RF module will be muted during the reset process.
This function is useful for clearing latched fault conditions in SSPA units
under N+1 system control;
• 3.Coms only — Resets only communication parameters. If unmuted, the
SSPA maintains an unchanged RF output level during reset. Remote
COM links will be dropped and re-enabled with selected parameters;
• 4.ClrFaults — Clears all latched faults and remaining fault history infor-
mation. SSPA remains fully operational during the process;
• 5.MemMode — Allows alternate SSPA settings retention function. Two
choices are allowed:
○ RAM Mode — In this mode SSPA will not backup any settings chang-
es to internal EEPROM. This mode is optional and needs to be set by
the user every time when SSPA endured power cycle or I/O card reset. This mode is beneficial when the SSPA application requires frequent changes to the SSPA state (such as mute/unmute or attenuation changes). Since any EEPROM device has limited write cycles,
RAM mode allows the user to execute unlimited settings changes. If
the SSPA experiences a power or reset cycle in RAM mode, it will use
the last saved settings setup before RAM was engaged;
○ EEPROM mode — Default SSPA mode. Without user intervention,
the SSPA will retain this mode of operation. All changes to settings
setup performed over local or remote interface will be backed up to
EEPROM within 3 seconds time interval. If the SSPA experiences a
power cycle or reset, the last saved set of settings will be applied to
the unit upon each power up or I/O card reset. Any EEPROM device
has a limited ability to endure write cycles. Maximum write cycles ability for SSPAs with firmware version prior to 6.00 is 150,000 times. After exciding write cycles limit, the SSPA will operate in RAM mode,
utilizing a default set of settings on each power up. Firmware version
above 6.00 allows 3,000,000 minimum write cycles before opting out
to RAM mode;

units; or System of 16 units. A single 5RU chassis in N+1 operation utilizes a system of
2 units.
Units connected to a N+1 system must have an identical N+1 array selection or have
N+1 operation disabled. A unit connected to a N+1 link cable with the N+1 option disabled will not be controlled by a N+1 Master. To the Master unit, it will appear as a faulted chassis.
2.2.6.6.2 N+1 Address
This option allows the selection of the unit’s N+1 priority address. All units in a N+1
array must be unique and with a contiguous N+1 address.
The unit with the lowest N+1 address has the highest priority when the system selects
a new Master unit in the event of the failure of the assigned Master unit. A unit with Address 1 will be the default Master unit. If Unit 1 fails, Unit 2 will take its place as the
Master unit.
2.2.6.6.3 Auto Gain Control
This option allows the user to enable or disable the N+1 Automatic Gain options.
• 1.AutoGain 5dB — When Auto Gain is enabled, the system will automat-
ically back off from maximum linear gain and reserve 5 dB of attenuator
range for gain compensation. When this option is enabled, the N+1 Master unit default System Information page will display: AutoGain(dB):XX.X
• 2.AutoGain Off — When Auto Gain is disabled, the system can be ad-
justed as if it was a single SSPA unit, attenuating system gain between 0
and 20 dBm. System gain will not apply automatic gain compensation if
any of the units in the N+1 redundancy array fails. When this option is
disabled, the Master unit default System Information page will display:
SSPAGain(dB):XX.X.
56 205356 REV T 3 RU SSPA Chassis Operations Manual
• 3.Keep Alive — The Keep Alive setting disables the automatic mute
function when a module enters a fault condition. This option may be beneficial in systems where the N+1 option is used only as a convenient single point of control, rather than as a redundancy control measure. Consult the factory on the use of this option.
• 4.Flex Gain — Flex Gain is a form of automatic gain control for N+1 sys-
tems. This control option has the same basic operation principles as the
standard Auto Gain option except that the gain reserves and amount of
gain compensation differ. This setting is designed to serve the special
gain compensation needs of hybrid PowerMAX SSPA systems.
When Flex Gain mode is enabled, the Master unit of the PowerMAX system automatically reserves a predetermined amount of attenuation to
each amplifier in the system and reduces overall system gain. In case of
one or more amplifier unit failures, the system will return a certain amount
of reserved gain in order to compensate system gain degradation from
the failed unit(s).
In the case of hybrid 4- and 2-way modes, the Master unit monitors the
amplifiers placed in standby mode and provides the proper amount of
gain compensation for these system configurations.
2.2.6.6.4 N+1 Info
When selected, the menu shown in Figure 2-14 is displayed and used for N+1 system
troubleshooting.

Note: The values shown do not indicate the current system state, but
instead offer a history of any fault occurrences.
• Last Fault/Ticks — Shows different information for Master and Slave
units. On the Master unit, it displays the unit address of the last detected
fault in the N+1 system. If the display shows “000”, that indicates no fault
instances since the unit assumed its Master state. On Slave units, the
value displayed is the number of system clock ticks remaining since the
last Master unit call. The Slave unit will assume Master state when the
tick count reaches 0.
• Fault Cause — Master unit only. Displays the cause for the last detected
N+1 unit fault. Possible values include “None,” for no faults; “Timeout,” if
a Slave unit fails to respond to a Master request for three (3) consecutive
queries; or “Summary,” if a unit exhibited a Summary fault.

2.3 N+1 Operational Basics (Single Unit)
A single SSPA unit may be operated in N+1 mode in order to take advantage of the
Auto Gain Control features described in Section 2.2.6.6.3. In this case, each SSPA
module within the SSPA chassis is counted as a separate N+1 entity. For example, a
two-module 5RU chassis acts like a two-way N+1 array.
N+1 array indexing also accounts this type of functioning. Each 5RU chassis occupies
a segment of N+1 addressing equal to the number of modules; i.e., 2 modules = 2 addresses.
The remaining N+1 functions remain the same. When one of the internal modules develops a failure, it will be forced to mute by the internal SSPA controller. The unit will
develop a summary alarm, but will remain in N+1 master mode (if it was prior to failure). Multi-module units will delegate a new master mode only when all internal modules develop a failure.
Note: With multi-module RM SSPA chassis configurations, the N+1
system will require fewer chassis to form a N+1 redundancy array.
Examples of 4-way N+1 systems:
One (1) four-module 5RU, 6RU, or 7RU chassis;
Two (2) two-module 5RU, 4RU or 3RU chassis;
Four (4) one-module 4RU or 3RU chassis.
2.4 N+1 Operational Basics (Two or More Units)
A system which utilizes two or more 5RU SSPA chassis in an N+1 configuration may
be operated directly from the front panel as if it was a single very high power SSPA.
Any 5RU SSPA chassis in the system can serve as the Master Module single point of
control.
2.4.1 Selecting the Master Module
The selection of the Master Module is fully automatic and shifts from one SSPA to another based on the priority ranking assigned to the modules comprising each SSPA
unit. A lower priority index number (referred hereafter as the N+1 Address) means a
higher rank in the N+1 hierarchy. The fault-free unit with the lowest N+1 address is selected as the N+1 Master Module. The remainder of the units become N+1 Slave units.
Slave unit settings are under full control of the Master unit. Any system-related setting
change made on the Master Module automatically propagates to the Slave units to
keep all units under N+1 control in sync.
3 RU SSPA Chassis Operations Manual 205356 REV T 59
If the Master Module develops any kind of major fault condition, it delegates its Master
privileges to the unit which is next in N+1 ranking and becomes a slave unit. This type
of control architecture eliminates a single point of failure and achieves true N+1 system
redundancy.
The Master Module is designated with a lit Online indicator and VFD display showing
the overall system state. See Figure 2-15.
Figure 2-15: Front Panel Display, Master Unit (Online Indicator Illuminated)
The Online indicators of the Slave units are always turned off and the VFD displays the
message shown in Figure 2-16.
Figure 2-16: Front Panel Display, Slave Unit (Online Indicator Dark)
Any unit that develops a major fault condition will be automatically muted to avoid any
side effects of the faulted unit on overall system performance.
The Master Module offers two extra informative menu screens for displaying system
level information such as: System forward and reflected power levels, system wide
gain or attenuation, amount of faulted SSPA chassis in the system, etc.
To avoid control conflicts, slave units are forbidden to gather system-wide information,
therefore these system wide information screens always hidden on N+1 Slave units.
2.4.2 Controlling System Operation
The N+1 system is under the control of the Master Module at all times. Any systemwide settings changes (local or remote) need to be performed on the Master Module. If
a setting is adjusted on a Slave unit, the Master Module will erase and override it with
the current system setting.
Some settings are not controlled by the Master Module because they are used for unit
identification or required for local adjustment during maintenance. Settings such as the
SSPA Network Address, N+1 Address, and IP Address are not enforced by the Master
Module and need to be set individually at every SSPA chassis.
The setting for enabling/disabling/sizing the N+1 system is also not controlled by the
Master Module. This setting allows the user to virtually remove individual SSPA units
from the N+1 control array for maintenance and troubleshooting.
60 205356 REV T 3 RU SSPA Chassis Operations Manual
2.4.3 N+1 Addressing
During initial system installation, an appropriate N+1 address has to be selected for
each unit in the system. Each unit should be assigned a unique N+1 address. The valid addressing range is 1 to 16 for any type of system configuration. Address 0 is reserved for factory debugging and should not be used. Assigning an address higher
than the total number of SSPA chassis in the system (i.e., address 10 for a system
comprising four 5RU SSPA units) makes the unit thus assigned invisible to the Master
Module. The unit will continue to receive commands from the Master Module.
To set the N+1 address of a particular SSPA unit, press the Main Menu key; select
6.Redundancy and press the Enter key; select 6.N+1 and press the Enter key; select
2.N+1 Addressing and press the Enter key. Enter the desired address by using the
Left Arrow [◄] and Right Arrow [►] keys to increment the ones place and the Up Arrow [▲] and Down Arrow [▼] keys to increment the tens place.
The N+1 address order is not important for system operation. Assign the lowest address to the unit located most conveniently to the user. Subsequent addresses should
be assigned while keeping in mind the accessibility of the front panel controls.
See Section 3.2 for directions on changing the N+1 hierarchy of SSPAs in an active
system.
2.4.4 Adjust System Gain
Nominal system gain with Auto Gain enabled is 65 dB; nominal system gain with Auto
Gain disabled is 70 dB.
To adjust the gain of the system, press the Main Menu key; select 3.Operation and
press the Enter key; select 5.Attenuation and press the Enter key. Alternately, from
any of the System Information menus described in Section 2.3.1, press either the Left
Arrow [◄] or Right Arrow [►] key. Enter a value between 0 and 20.0 dB. If Auto Gain
is enabled, the system will reserve 5 dB of attenuator range for gain compensation and
attenuation is limited to a value between 0 and 15.0 dB.
2.4.5 N+1 Automatic Gain Control Option
Any modular hitless SSPA system may exhibit natural gain drift when one or more individual SSPA chassis is removed from the system or malfunctions. The automatic gain
control option allows the system to maintain a constant gain level during such events.
This feature is user selectable and can be activated from the SSPA front panel or a remote interface.
To toggle the Automatic Gain Control option, press the Main Menu key and select
6.Redundancy and press the Enter key; select 6.N+1 and press the Enter key; select
3 RU SSPA Chassis Operations Manual 205356 REV T 61
3.Gain Control and press the Enter key. Select either Auto Gain On or Auto Gain Off.
When this option is activated, the SSPA will automatically reserve 5 dB of attenuator
range for future gain compensation. This will reduce the maximum SSPA gain by 5 dB.
The attenuator range will also be reduced to 15 dB.
Five dB of reserved attenuator range allows the system to fully auto compensate gain
when one SSPA module in a single 5RU SSPA unit enters a fault condition.
2.4.6 N+1 RF Power Measurements
The N+1 system may be equipped with a dedicated RF power measurement unit. The
RF Power Detector provides RMS measurement of Forward and Reflected RF power
directly at the output waveguide and this reading is acquired by the N+1 Master unit.
Besides N+1 system level power detection, each individual SSPA unit may be
equipped with its own RF power detector. This reading can be viewed at each SSPA
unit and may be used for troubleshooting individual SSPA units.
To view the RF power detector reading on the front panel, press the Main Menu key,
select 1.SysInfo and press the Enter key; press the Down Arrow [▼] key to get to
Sys Info Page 1.
2.4.7 N+1 Fault Detection
The N+1 system carries comprehensive fault detection logic. Each SSPA chassis processes its internal fault conditions as if it was a standalone unit. All N+1 Slave units report any fault state to the Master Module, which is responsible for system wide fault
state handling. Failure of any single SSPA unit leads to a minor N+1 alarm on the Master Module. This type of fault condition will not produce a summary system alarm.
The user may view the number of faults in a system from the front panel by pressing
the Main Menu key of the Master Module; press the Up Arrow [▲] key to get to N+1
Master Info Page 2. Any detected SSPA unit alarms present in the system will be displayed at the “N+1 Alarms” screen.
If the Master unit detects two or more failed units, it will report a system-wide Summary
alarm (Summary alarm LED on the Master unit will illuminate). The cause of the alarm
will not be evaluated by the Master Module. To find cause of the failure, the operator
will need to evaluate the local fault conditions of the failed SSPA unit.
62 205356 REV T 3 RU SSPA Chassis Operations Manual
2.5 Reflected Power Option
When this option is installed, the user may measure the amount of reflected RF power
present at the amplifier’s output flange, with a dynamic range of 12 dB starting at the
maximum RF output.
For example, an amplifier with 50 dBm (100W) of maximum forward RF would be capable of reading reflected power levels from 38 dBm (6W) to 50 dBm (100W). The
amount of reflected power can be viewed on the Front Panel Display screen:
1. Press the Main Menu key on the front panel;
2. Select 1.SysInfo and press the Enter key.
Note: All Teledyne Paradise Datacom SSPAs are protected from short-
term 100% reflected power conditions. Teledyne Paradise Datacom does
not recommend operating the amplifier under a sustained condition of
100% reflected power. The addition of the reflected power sensor option
allows the operator to monitor the amount of reflected power on the
amplifier for the purposes of identifying issues with the transmission
signal. The user may set up a Major Alarm trigger for High Reflected
Power conditions in the Teledyne Paradise Datacom Universal M&C
software. This alarm only indicates the presence of the high reflected
power condition, and will not alter the amplifier settings to compensate for
the condition.
2.5.1 Reflected Power Alarm
Because the reflected power circuitry is not a true VSWR measurement, but simply a
measure of absolute reflected power, it is possible to set an alarm level. In units with
the reflected power monitor option, the alarm level is factory pre-set as a major alarm
at 80 percent of the amplifier’s rated power.
For example, an amplifier with 50 dBm (100W) of output power would have an alarm
level set to 49 dBm (80W).
Note: Teledyne Paradise Datacom does not recommend changing this
setting from the factory pre-set due to possible frequent false alarms that
may be generated if set at a much lower level. However, it is possible to
adjust the setting in the Universal M&C software.

Section 3: Troubleshooting
and Maintenance
3.0 Troubleshooting Faults
The Rack Mount SSPA has five fault condition LEDs on left side of the
front panel which reflect a summary fault, and fault states for voltage,
temperature, current and the amplifier’s power supply. Additional fault
reporting is available via the front panel display readout. Figure 3-1 shows
a representation of the fault condition indicators.
The following sections describe steps the user should take to determine
the cause of a fault state in a stand-alone amplifier.
3.0.1 Summary Fault
This fault reflects the overall state of the SSPA. Only “major” faults affect
the summary fault state. Some faults may or may not affect the summary
fault depending on the SSPA settings.
3.0.2 Voltage Fault
The user should check the voltages displayed on page 6 of the system information
menu of the front panel display. If the voltages are outside of the normal output ranges
as described in Section 2.2.1.6, consult the factory.
3.0.3 Temperature Fault
If the amplifier experiences a temperature fault, follow the steps below:
• Check the ambient temperature of the room where the SSPA is installed.
Check the environmental specifications on the specification sheet for
your SSPA. If the ambient temperature is beyond these limits, the unit
may experience a temperature fault. If this is the case, action will need to
be taken to bring the ambient temperature into the specified range.
• If the ambient temperature is within the specified range and the unit still
experiences a temperature fault, the operator should perform a visual inspection of the fans to make sure they all appear to be spinning.
• Check the front panel read-out out for a fan fault. This can be found under the system information portion of the main menu on the front panel. If
a fan fault is present, the operator may need to replace the fan that is not
functioning.
Figure 3-1:
Front
panel fault
display
3 RU SSPA Chassis Operations Manual 205356 REV T 65
• The operator should check the booster board voltages on the front panel
display. This reading can be found under the system information portion
of the main menu on the front panel. The voltage should read approximately 28 VDC for each of the fans in the SSPA. If the booster voltage is
lower than 25 VDC, the operator should check for a power supply fault
and follow the procedures to handle this problem.
3.0.4 Current Fault
In the case of a current fault, follow the tips below:
• Check the current displayed on Page 6 of the system information menu
of the front panel display. If the amplifier is in the mute state, current
should drop within a range of 0 to 5 A.
3.0.5 Power Supply Fault
In the case of a power supply fault, follow the steps below:
• When using an external power supply with the amplifier, verify that all
power supply modules are operating normally. Replacement power supply modules are available through technical support.
• Check the power supply readings on the SSPA front panel. Observe any
fluctuations and record the level.
• Mute the amplifier. Check the power supply readings on the SSPA front
panel. Sometimes muting the amplifier corrects the power supply fault.
• Check the DSUB (alarm) cable that connects between the SSPA and the
external power supply. If this cable is pulled or making poor contact, this
may cause a false power supply alarm.
• Note that the amplifier M&C logic is designed to mute the amplifier is
more than one power supply module faults. If the DSUB power supply
alarm cable is removed, the amplifier will continue to operate but will
show a persistent power supply fault.
3.0.6 Fan Fault
In the case of a fan fault, follow the tips below:
• Inspect the fans.
• The user should check the booster board voltages on the front panel dis-
play. This can be found under the system information portion of the main
menu. The voltage should read approximately 28VDC for each of the
fans in the SSPA.
• If necessary, replace the fan (See Section 7.1.1).
66 205356 REV T 3 RU SSPA Chassis Operations Manual
3.0.7 Low RF Fault
In the case of a Low RF alarm, follow the steps below.
• Check the forward RF level on the front panel readout under the system
information menu. If the user has access to a power meter or spectrum
analyzer, this power level can be verified by means of the output sample
port on the front panel.
• Compare this value to the forward RF alarm threshold level in the Fault
Set-up menu. If the Threshold level is higher than the actual RF output
level, this will produce a low RF alarm, providing that the low RF alarm
option is enabled.
• At this point, be sure that the forward RF alarm threshold level is set to a
value corresponding to the desired output level for the SSPA in question.
The factory pre-set for this value is always 10 dBm below the specified
P
compression point of the SSPA. However, you may wish to set this
1db
level closer to the desired output level in order to catch any minor fluctuations below the set level. If the level is set too high, the low RF alarm may
be displayed when there are no legitimate problems. If the RF input signal has been lowered, this will also lower the output of the SSPA and
may cause a low RF alarm.
• If the user is certain that the amplifier is in an alarmed state due to problems other than the ones stated above, the user should verify that no other fault conditions are present. If a power supply fault, current fault, or
voltage fault is present, this may also cause the low RF alarm to show. If
any of these is the case, the user should refer to the sections corresponding to that specific fault.

3.1 Modular SSPA Architecture
The Teledyne Paradise Datacom SSPA Chassis consists of a modular design, which
allows for quick and easy maintenance and replacement in the event of a catastrophic
failure of one of the SSPA components.
3.1.1 Removable Fans (Intake and Exhaust)
The intake and exhaust fan assemblies can be easily replaced with minimal interruption of service. Replacement fans are available from Teledyne Paradise Datacom.
The front panel (intake) fan tray is secured by four captive thumb screws. To remove,
loosen the screws and carefully remove the fan tray from the chassis. See Figure 3-2.
Unplug the fan power cord from the connector at the top right of the plenum to fully
remove the fan plate assembly. See Figure 3-3.

Connector to Remove Fan Tray
The exhaust fans on the rear panel are each secured by (4) captive thumb screws. To
remove, loosen the screws and carefully remove the fan assembly from the chassis.
Unplug the fan power cord from the connector. See Figures 3-4 and 3-5.
3.1.1.1 Fan and Heatsink Maintenance
It is recommended that the cooling system of the SSPA be checked at least once per
month. If the environment in the area where the amplifier is being operated produces a
large amount of dust and debris, this check should be performed more frequently.
The intake fans of the amplifier can pull airborne debris into the enclosure, and fill the
spaces between the heatsink fins. See Figure 3-6. As this debris builds up inside the
amplifier, the airflow which is important in cooling the amplifier is impinged.
Figure 3-6: Example of Dust Blocking Heatsink Fins
Blockage of the heatsink will cause the internal temperature of the amplifier module to
rise above what is considered as normal operating conditions. While the amplifiers
have thermal protection, long periods of elevated temperatures could reduce amplifier
life.
The front panel menu can be used to check the amplifier base plate temperature. The
base plate temperature should normally not exceed 75 °C. To view the SSPA base
plate temperature, press the Main Menu key and select 1.SysInfo and press the Enter
key; press the Down Arrow (▼) key seven (7) times. If the base plate temperature
exceeds 75 °C, it is one indicator that the system’s airflow requires maintenance.
Note: The amplifier’s temperature alarm threshold is set to 85 °C. If the
base plate temperature reaches 85°C, the front panel Temp Fault LED
will activate. If the temperature reaches 90°C, the unit will shut down.
The heatsink fins should be visually inspected for excessive dirt and debris build-up. If
it appears there is excessive debris in the fans or heatsink; the fan tray can be removed for easy cleaning.
1.Using a Philips head screw driver, loosen the thumbscrews holding the front
fan tray in place.
2.Remove the front panel fan tray. See Figure 3-2.
3.Unplug the fan power cord from the power pole connector. See Figure 3-3.
4.Use the shop vacuum to collect all dust and debris.
3 RU SSPA Chassis Operations Manual 205356 REV T 69
5.Use a can of compressed air to dislodge any dust or debris lodged within the
heatsink fins and the fan assembly. Ensure that the heatsink fins are free
from all debris. See Figure 3-7.
Figure 3-7: Heatsink Fins Cleared of Debris
6.Plug the fan power cord into the power pole connector.
7.Re-insert the front panel fan tray.
8.Tighten the thumbscrews which hold the front fan tray in place. Tighten to
snug using a Philips head screw driver.
3.1.2 SSPA Module Removal
Important note: The SSPA module should not be removed while the
Rack Mount SSPA is under warranty. Doing so voids the warranty.
The 3RU Rack Mount SSPA Chassis houses one SSPA module beneath the top cover
plate, as shown in Figure 3-8.
Figure 3-8: Module Placement: C-band, left; Ku-band, right
The cover plate is held in place with 16 6-32 x 1/4” flat-head screws. Remove power to
the amplifier before removing this hardware.
Once the cover is removed, disconnect the power cables from the SSPA module. Also
disconnect the semi-rigid coax connections on the RF IN, Sample and optional
70 205356 REV T 3 RU SSPA Chassis Operations Manual
Reflected Power ports. Lastly, remove the four (4) 4-40 x 3/8” socket head cap screws,
with lock and flat washers, that secure the M&C ribbon cable to the module, and
disconnect the ribbon cable from the M&C port.
The SSPA module is secured to the heat sink plate by ten (10) 6-32 x 1-3/8” socket
head cap screws. The module is also attached to the waveguide output via socket
head cap screws [Four (4) 6-32 x 5/8” for Ku-band; eight (8) 10-32 x 5/8” for C-band]
with flat and lock washers. These must all be removed before the SSPA module can
be removed from the chassis.
3.1.3 Power Supply Module Removal
Certain 3RU SSPA Chassis use an internal power
supply module, which may be removed from the
front panel.
To remove a power supply module, simply loosen
the retaining screw on the front panel by turning
counter-clockwise then flip the top of the retaining
clasp away from the module. Grasp the handle and
pull the module firmly out of the power supply
chassis. See Figure 3-9.
To replace a module, slide the new unit slowly into
the empty slot in the housing until it is properly
Figure 3-9: Remove Power
Supply Module
seated, taking care not to slam or unnecessarily
force the unit into the slot. Secure the module by flipping the retaining clasp up until it
is flush with the module, then tighten the retaining screw.
3.1.3.1 External N+1 Redundant Power Supply
Amplifiers may be configured with an external N+1 redundant power supply. Each
power supply chassis can house up to four (4) power supply modules, and is fitted with
one more power supply module than necessary to power the amplifier.
A power supply modules can be removed and replaced from the power supply chassis
without taking the amplifier offline.
To remove a power supply module, lift up on the restraining tab on the front panel.
Grasp the handle and pull the module firmly out of the power supply chassis.
To install the power supply modules into the chassis, place a module into one of the
empty bays of the chassis making sure that the release knob is located at the lower left
side of the opening and the handle is at the top. Slide the module slowly into an empty
slot in the chassis until it is properly seated, taking care not to slam or unnecessarily
force the unit into the slot.

3.1.4 Removable Controller Card (Rear Panel)
The Rack Mount SSPA Controller card is a removable assembly located at the rear of
the SSPA. The controller card includes connections for the Switch (J3), Serial Main
(J4), Serial Local (J5), Programming (J6), Parallel I/O (J7), Link (J8) and Ethernet (J9)
ports.
To remove this card assembly, loosen the two restraining thumbscrews at the top left
and bottom right of the assembly. See Figure 3-10. Slide the assembly straight back
from the cavity, as shown in Figure 3-11.
Retaining Thumbscrews
Figure 3-10: Loosen Retaining
Thumb Screws
Figure 3-11: Remove Card to Access
Programming Connectors
A replacement controller card is available from the factory.
The DigiCore5 controller card is equipped with a configuration DIP switch block, S1.
This switch allows the adjustment of certain configuration parameters.
• S1.1 - S1.6 — Factory use only; Preset position is ON-ON-ON-OFF-OFFOFF;
• S1.7 - S1.8 — These settings allow Enable/Disable galvanic isolation of
the Main serial port (J4). Factory preset for these ports is OFF – OFF.
This configuration disconnects the Serial Main Ground pin from the chassis ground. If, for any reason, the galvanic ground isolation is not desired,
this feature could be disabled by changing the position of switches S1.7 S1.8 to ON – ON.
Warning! Disabling galvanic ground isolation increases the risk of
serial port electrical damage during a lightning strike, or under
other ground potential difference issues. If galvanic isolation is
disabled, Teledyne Paradise Datacom suggests connecting or
disconnecting the wire harnesses to this port only when the equipment is powered down.

3.2 Changing N+1 Hierarchy
Normally, the hierarchical structure of the N+1 array must be set during initial system
setup. However, the operator may change the N+1 addressing hierarchy at any time.
To ensure uninterruptible system operation during such system maintenance, certain
procedural steps must be followed.
3.2.1 Changing Hierarchical Order of Slave Units
To change the hierarchical order of N+1 slave units without interrupting the system
operation:
Important! The Master unit will lose sight of one of the slave units
for the duration of this procedure. If the system is in Auto Gain
mode, this condition will cause gain overshoot. Temporarily turn off
the Auto Gain feature.
1. Turn off Auto Gain setting if needed.
2. For the first slave unit, temporarily select an N+1 address setting outside the
maximum address for the current N+1 array. For example, in a system of
4 units, select address 5 or above; for a system of 8 units, select address
9 or above; etc.
3. For the second slave unit, change its N+1 address to match the previous
N+1 address of the first unit.
4. Change the N+1 address of the first slave unit to match the previous N+1
address of the second unit.
5. System addressing hierarchy is now exchanged between first and second
unit. Turn on Auto Gain option if required.
3.2.2 Exchange N+1 Privileges Between Master and Slave Units
To delegate master privileges to a slave unit without interrupting system operation:
1. On the slave unit intended to be set as new Master unit, set the N+1 address
value to “0”. Assuming the unit is free from internal faults, the unit will
instantly change its mode to Master.
2. On the former Master unit, select its N+1 address to match the address of
the former slave unit.
3. On the new Master unit, change the N+1 address value from “0” to the
address value of the former Master unit.
3 RU SSPA Chassis Operations Manual 205356 REV T 77
3.2.3 Add an SSPA Unit to the System
If one of the SSPA units was removed from the system or it down for maintenance,
adding it back to system array may cause an unexpected change to a system state. To
provide uninterruptible system operation, follow the procedure below.
1. Locate the current Master unit and change its N+1 address value to “0”;
2. If the new unit has an unknown N+1 address or has not been configured for
N+1 operation, turn off the Auto Gain option;
3. If the new unit has a known N+1 address in conflict with one of the current
SSPA slave units, resolve it by changing address of the current Slave unit.
4. Add new unit to system. Make sure newly added unit assumed N+1 slave
mode. Make sure current Master unit doesn’t detect any N+1 faults.
5. Change Master unit N+1 address from value “0” to it’s previous value.
6. Follow Scenario 1 and 2 if hierarchical order change is required.

Section 4: Operation of a
1:1 Redundant System
4.0 Introduction
This chapter describes how to configure and control a 1:1 redundant system which
consists of two Teledyne Paradise Datacom SSPAs and a waveguide/coaxial switch.
Two Rack Mount SSPA units can be connected in a 1:1 redundant configuration, which
can automatically switch to an operating amplifier if the on-line SSPA develops a
system fault. In order to work in redundant mode, both SSPAs must be properly
configured and interconnected. Because both SSPAs have a microprocessor unit, an
additional controller is not required.
Two amplifiers can be connected to each other and to a waveguide/coaxial switch.
One of the amplifiers is designated as “on-line”; the other is designated as “standby”.
The on-line SSPA receives the input RF signal and transmits an amplified RF signal to
the RF load. The output of the standby SSPA is terminated at the dummy load. Figure
4-1 shows a block diagram of a typical 1:1 Redundant System.
Figure 4-1: Block Diagram, 1:1 Redundant System
Two modes are available for the standby SSPA: “Hot” or “Cold” standby. An SSPA in
“Hot” standby mode remains fully operational (the preferred method). An SSPA in
“Cold” standby mode remains muted when off-line. This mode is only used where
prime power conservation is critical.
When the system is in “Auto” mode, if a summary fault develops in the on-line
amplifier, its state will be sensed by the standby SSPA through the link cable. If the
standby SSPA is in a non-faulted state, it will force the waveguide switch to reposition
and put itself into the online state. The process takes no more than 200 ms.
3 RU SSPA Chassis Operations Manual 205356 REV T 79
Figure 4-2: RM SSPA 1:1 Redundant Systems
Both SSPAs constantly monitor the waveguide switch position. The proper position for
the online SSPA is determined by the “Unit Status” setting. If the selected SSPA is
configured as “HPA1,” it will drive the RF switch to Position 1 to set itself to the on-line
state. Selecting unit status to “HPA2” will configure that SSPA to drive the switch to
Position 2 for the on-line state. In “Auto” mode, the online SSPA will make two
attempts to force the waveguide switch to take proper position before accepting its
new state.
4.1 Hardware
Two Teledyne Paradise Datacom Rack Mount SSPA units are used for a 1:1
redundant configuration. The units are connected to each other through a link cable,
which allows the exchange of online/standby statuses between SSPAs.
Both SSPA units are connected to the waveguide switch through a Y-cable. This
allows either amplifier to drive the switch to its proper position. Each unit must be
configured with a unique identity. If one SSPA is configured as “HPA1”, the other
should be configured as “HPA2”. Both SSPAs must be set to 1:1 Redundancy mode.
Figure 4-2 shows a 300W C-Band 1:1 Redundant System with an RCP2-1100
Redundant Controller.
80 205356 REV T 3 RU SSPA Chassis Operations Manual
4.1.1 Power Supply
Each SSPA may contain up to two 1200W, 12V power supplies, which supply power to
a waveguide switch via the Switch Port (J3) of the SSPA. The state of the power
supplies (referred to as “Boost1” and “Boost2”) can be monitored from the front panel
display and through remote serial protocol. Power supplies are fully protected from
over-current and over-voltage conditions and can reliably output up to 3A of DC
current.
4.1.2 RF Switch
The SSPA redundant system controls a waveguide/coaxial switch using the 6-pin rear
panel connector J3. The switches are controlled by applying +28V to the common of
the switch and pulsing either position to the ground. The system then verifies the
position of the switch.
4.1.3 Switch Connector
The 6-pin connector J3, Molex P/N 43810-002 can be located on the SSPA rear panel.
This connector is used to interface with the RF switch. Paradise Datacom recommends
the use of following parts to build a mating pair to this connector (all P/N by Molex): Pin
Crimp: 39-00-0039; receptacle: 39-01-2060; strain relief: 15-04-0296.
Table 4-1 shows the proper wiring to the MS3116F10-6S RF switch connector,
commonly used on waveguide switches. Figure 4-3 shows an outline drawing of a
typical switch connector cable. Figure 4-5 shows a representation of how the switch
and link cables are connected between the SSPAs and the waveguide switch.

4.2 Installation and SSPA configuration
The two RM SSPA units are designed to be installed in a standard EIA rack.
Warning! Ensure the equipment rack is properly supported to prevent tipping forward
when the amplifiers are extended on their slides. SSPA 1 (HPA1) should be on the top
of SSPA2 (HPA2). Waveguide, semi-rigid cables (marked with the amplifier/switch
connections), Switch cable and link cable must be attached to the corresponding
connectors on both amplifiers.
4.2.1 Configuring Amplifiers to Work in 1:1 Redundant Mode (Internal Control)
4.2.1.1 Setting SSPA1 to Work in 1:1 Mode
1. From the front panel of SSPA1, press the Main Menu key;
2. Select 3.Operation and press the Enter key;
3. Select 5.Sys.Mode and press the Enter key;
4. Select 2.1:1 Mode and press the Enter key;
3 RU SSPA Chassis Operations Manual 205356 REV T 83
4.2.1.2 Setting SSPA1 Switching Mode
1. From the front panel of SSPA1, press the Main Menu key;
2. Select 6.Redund. and press the Enter key;
3. Select 1.Switching and press the Enter key;
4. Select desired SSPA switching method and press the Enter key.
Note: SSPA2 must use the same switching method as SSPA1.
4.2.1.3 Setting SSPA1 Unit Status
1. From the SSPA front panel press the Main Menu key;
2. Select 6.Redund. and press the Enter key;
3. Select 4.Status and press the Enter key;
4. Select 1.HPA and press the Enter key.
Note: SSPA2 unit status must be set to HPA2.
Repeat steps 4.2.1.1 through 4.2.1.3 for SSPA2.
4.2.2 Online / Standby Amplifier Selection
To determine the on-line state of a particular SSPA, check that the “Unit 1” button on
the front panel keypad (See Figure 4-6) is illuminated. To put the SSPA in Standby
mode, press the “Unit 1” key and the light should go off. If the system is in “Auto”
mode, the second SSPA will accept the on-line state only if there is no summary alarm.
Figure 4-6: “Unit 1” Indicator from Front Panel
The “Unit1” LED on the second SSPA will illuminate, indicting it is on-line and will
rotate the waveguide switch to the correct position. If the second SSPA does not
accept the on-line state, the first SSPA will revert to the on-line state after 1 second.
Note: Only the Online unit can be switched to Standby mode. The re-
verse process, switching the standby unit to the on-line state, will not
work.
In Manual mode, the Standby SSPA will always accept the Online state regardless of
its own fault status. The user can verify the state of the waveguide switch by browsing
to informative screen [3] on the front panel display. Item RFSW1 will indicate the state
of the waveguide switch, as detected by the SSPA. If the switch position can not be
detected; “Fault” will be displayed.
84 205356 REV T 3 RU SSPA Chassis Operations Manual
4.2.3 Auto Versus Manual Switching Mode
Normal operation mode for a 1:1 redundant configuration is “Auto”. This mode provides
automatic detection of SSPA faults and switchover to the operational SSPA. The system is also protected from operator errors; selecting a faulted SSPA is not allowed. In
situations when system maintenance must be performed, “Manual” mode should be
used. In “Manual” mode, the operator can select the on-line and standby SSPA by
pressing the “Unit1” key. The system will not provide automatic switchover from a faulted SSPA, but rather will keep the selected SSPA online, regardless of its state.
Note: In order to function normally, both SSPAs in the system must uti-
lize the same switching mode.
4.2.4 Physically Rotating Transfer Switch
It is possible to physically rotate the shaft on the transfer switch to change the online
and standby amplifiers positions. This can be done either in manual or automatic
mode. When the switch is physically rotated in automatic mode the online SSPA will
attempt to return the switch to its previous position. The SSPA will make two attempts
to return the switch before accepting the new position.
4.2.5 Switchover Muting
The following option was introduced into the SSPA control setup to overcome a
problem with microwave arcing, which may potentially damage a switching component
if the switching RF power exceeds 400 Watts. This particular problem becomes a
critical issue if coaxial RF pass switches are used.
In general, all Teledyne Paradise Datacom SSPAs are well protected against high
reflected power conditions, which may take place during output microwave switchover.
However, waveguide or coaxial switches will develop an internal electrical arc during
switchover if the output power is significant. Such conditions will not lead to instant
failure, but over time may diminish some critical RF switch characteristics.
If this option is activated, the system ability to output RF power will be bonded to the
switch position sensing circuitry. Such circuitry consists of the following components:
SSPA electronic switch position detector; wiring harness between SSPA and RF
switch; RF switch position sensors. Failure of any of these components will lead to a
break in transmission. The factory strongly recommends to NOT turn on this option unless absolutely necessary.
To enable switchover muting from the SSPA Front Panel:
1. Press the Main Menu key;
2. Select 4.Flt.Setup and press the Enter key;
3. Select 3.RF Switch and press the Enter key;
4. Select 4.MutedSwitch and press the Enter key.

Section 5: Operation of a
1:2 Internal Redundant System
5.0 Introduction
Three Rack Mount SSPA units with controller firmware version greater than 2.50 and
I/O board hardware version greater than 1 can be connected together to form a 1:2
redundant system without a separate 1:2 redundancy controller (internal redundancy).
The system provides automatic switchover to the spare SSPA to either polarization
path in case of a primary SSPA malfunction. In the case of two SSPA malfunctions, the
backup SSPA can be switched to either polarization path, according to a polarization
priority selection setting.
The standard 1:2 configuration has HPA1 online in the polarization 1 path, HPA3
online in the polarization 2 path, and HPA2 acting as spare backup for ether HPA1 or
HPA3 (see Figure 5-1).

Figure 5-1: Block Diagram, 1:2 Redundant System
A 1:2 redundancy system normally requires a separate redundancy controller (RCP).
The RCP is used to constantly check the state of the controlled HPAs and, in case of
malfunction, rotate the waveguide switches according to an internal logic table.
Operation of a 1:2 system with controller is more fully discussed in the Redundant
Systems Controller Operations Manual, document number 205933.
Teledyne Paradise Datacom also offers an internal 1:2 redundancy system, where the
extra controller is not required and the state of the system is negotiated between all
three HPAs over the redundancy link and switch cables. In this system, the link cable is
used to pass information regarding the standby/online state between the HPAs. The
switch cable is used to drive waveguide switches and determine their current position.
3 RU SSPA Chassis Operations Manual 205356 REV T 87
The system current state is determined by the position of the two waveguide switches.
Each HPA constantly monitors the state and assumes an online or standby state from
the switch position. All three HPAs need to be configured to “HPA1”, “HPA2” and
“HPA3” status according to their relative position to the waveguide switches. These
settings need to be provided to each HPA by the operator through the HPA front panel
menus or through a remote control interface.
The system is capable of operating in 2 modes: “Auto” and “Manual”.
Normally, the system needs to be configured in “Auto” mode. In this mode, when an
HPA develops a summary alarm, the system will automatically switch to the backup
HPA. “Manual” mode should be used only for maintenance purposes. During this
mode, automatic switchover will be performed if a malfunctioned HPA’s controller card
is completely dead. If an HPA has a summary fault, but the controller card is still alive
then HPA will remain in online state.
Both modes allow the user to switch HPAs from online to standby state by pressing
“Unit1” button on the front panel or through command on remote interface. Typical
switchover time is 200mS or less. Switchover also can be performed by physical
rotation of one or both waveguide switches. Unlike internal 1:1 redundancy mode, the
SSPA will not prevent the operator from turning the switch.
5.1 Required Hardware
• Three RM SSPAs with controller card firmware revision better than 2.50
and I/O card version better than 1. Internal 1:2 redundancy mode for earlier hardware/firmware revisions is not available. If you purchased your
SSPA as a standalone unit or as part of a 1:1 system, consult with Teledyne Paradise Datacom to determine if the revision of digital controller is
1:2 enabled. 1:2 redundancy Mode, unit HPA status and polarization priority need to be selected on all connected HPAs.
• 1:2 link cable. The link cable allows redundancy state information to pass
between the HPAs and should be connected to the HPA’s Link Port, J8.
Important! Cable ends are not symmetrical! When connecting HPAs
with the link cable make sure that connected units HPA status
(HPA1, HPA2 or HPA3) match the labels on the link cable ends!
• 1:2 switch cable. This cable provides an electrical connection between
the HPAs and waveguide switches. The cable allows either HPA to con-
trol both waveguide switches.
Important! Cable ends are not symmetrical! When connecting, observe the labels!
88 205356 REV T 3 RU SSPA Chassis Operations Manual
5.2 Power Supply
Each SSPA may contain up to two 28V (depending on the power level of the SSPA)
power supplies, to supply power to the waveguide switch. The state of the 28V power
supplies (referred as “Boost1” and “Boost2”) can be monitored from the SSPA front
panel display or through the remote serial protocol. Power supplies are fully protected
from over-current and over-voltage conditions and can reliably output up to 3A of DC
current.
5.3 RF Switches
The SSPA redundant system controls a -28V waveguide/coaxial switch using the 6-pin
rear panel connector J3. The switches are controlled by applying +28V to the common
of the switch and pulsing either position to the ground. The system then verifies the
position of the switch.
5.4 Switch Connector
The 6-pin connector J3, Molex P/N 43810-002 can be located on the SSPA rear panel.
This connector is used to interface with the RF switches. Paradise Datacom recommends the use of the following parts to build a mating pair to this connector (all P/N by
Molex): Pin Crimp: 39-00-0039; receptacle: 39-01-2060; strain relief: 15-04-0296.

The 9-pin male connector J8 Link Port is used to link an HPA with the other two
redundant units in order to pass online/standby status information between them. The
link cable is an asymmetrical crossover cable. Take care to match the labels on each
cable with the HPA status of the units (i.e., plug cable end with label “HPA1” into the
SSPA with selected “HPA1” status, etc).
Warning! Do not remove this cable while the system is in operation!
The system will not operate properly.

5.6.1 Installation
All three SSPA units are designed to be installed in a standard EIA rack.
Warning! Ensure the equipment rack is properly supported to prevent tipping forward when the SSPAs are extended on their slides.
HPA3 should be located on the bottom of the rack, HPA2 should be located directly
above HPA3 and HPA1 should be located above HPA2. The waveguide assembly (or
semi-rigid coax cables) and mounting brackets connect the three units.
All three HPAs need to be configured for 1:2 mode (internal control). Each unit’s status
software setting has to be set to “HPA1”, “HPA2”, or “HPA3” according to the unit’s
physical position in the rack. See below for step by step instructions.
5.6.1.1 Configuring HPA to Work in 1:2 Redundant Mode (Internal Control)
1. From the HPA front panel, press the Main Menu key;
2. Select 3.Operation and press the Enter key;
3. Select 5.Sys.Mode and press the Enter key;
4. Select 3.1:2 Mode and press the Enter key;
Note: In a 1:2 system using a system controller (RCP2-1200), the
Sys.Mode for each amplifier in the system must be set to 1.Standalone.
5.6.1.2 Setting HPA1 Switching Mode
1. From the HPA front panel, press Main Menu key;
2. Select 6.Redund. and press Enter key;
3. Select 1.Switching and press Enter key;
4. Select desired HPA switching method and press Enter key;
Note: Each HPA must utilize the same switching method.
5.6.1.3 Setting HPA1 Unit Status
1. From the front panel of HPA1, press Main Menu key;
2. Select 6.Redund. and press Enter key;
3. Select 4.Status and press Enter key;
4. Select item 1.HPA1 and press Enter key.
Note: HPA2 unit status must be set to “2.HPA2” and HPA3 unit status
must be set to “3.HPA3”.
Repeat the steps above for HPA2 and HPA3.

5.6.2 Setting SSPA’s Polarization Priority
Polarization priority selection becomes very important in then case when two out of the
three SSPAs have developed summary faults. In this occasion, the remaining online
SSPA may redirect its output to support either polarization. This setting applies only for
HPA1 and HPA2. HPA3 has no physical ability to redirect its output to polarization 1
output due to obvious topological factors. The setting for HPA1 or HPA2 doesn’t have
to match and may be selected to suit the particular system needs.
To set SSPA polarization on any SSPA, follow steps below:
1. From front panel of SSPA, press the Main Menu key;
2. Select 6.Redund. and press Enter key;
3. Select 5.Priority and press Enter key;
4. Select desired polarization priority: 1.Pol1 or 2.Pol2;
5.7 Online/Standby Amplifier Selection
To determine the online state of a particular SSPA, check that the “Unit 1” button on
the front panel keypad (see Figure 5-5) is illuminated. To put an SSPA in standby
mode, press the “Unit1” key and the light should go off. If the system is in “Auto” mode,
the standby SSPA should accept an on-line state if cleared from a summary fault. The
“Unit1” LED on the standby SSPA will illuminate, indicating it is online and rotate the
waveguide switch(es) to the correct position to redirect its output power to the selected
polarity. If the standby SSPA doesn’t accept the online state, the first SSPA will revert
to the online state after 1 second.
Figure 5-5: “Unit 1” Indicator from Front Panel
The current SSPA’s polarity output selection can be monitored from the informative
menu of front panel display or through the remote control protocol. The standby SSPA
will indicate “None” as its priority selection. The on-line SSPA may indicate “Pol1” or
“Pol2”, depending on the current system state.
In Manual mode, the standby SSPA will always accept the online state regardless of its
own fault status.
The user can verify the state of the waveguide switches by browsing the informative
screen [3] on the front panel display. Items RFSW1 and RFSW2 will indicate the state
of the waveguide switches, as detected by the SSPA circuitry. If either switch position
cannot be detected, “Fault” will be displayed.

5.8 Auto Versus Manual Switching Mode
Normal operating mode for a RM SSPA in 1:2 redundant configuration is “Auto”. This
mode provides automatic detection of a SSPA fault and switchover to the operational
SSPA. The system is also protected from operator error; selecting a faulted SSPA is
not allowed. In situations when system maintenance must be performed, “Manual”
mode should be used. In “Manual” mode, the operator can select the online and
standby SSPA by pressing the “Unit1” key. The system will not provide automatic
switchover from a faulted SSPA, but rather will keep the selected SSPA online,
regardless of its state.
Note: In order to function normally, all SSPAs in the system must utilize
the same switching mode.
5.9 Physically Rotating Transfer Switch
It is possible to physically rotate the shaft on the transfer switch to change the online
and standby amplifiers. This can be done in either manual or automatic mode.
In “Auto” mode, the system will prevent the user from putting faulted SSPA online. The
on-line SSPAs will keep trying to rotate the switch until the proper configuration is restored.
If manual rotation is completed, the “Unit 1” LED of all system SSPA will change state
to reflect the new system configuration.
5.10 Parallel Port Special Functions
As with any redundant mode, each SSPA chassis will change some of its parallel I/O
functions to an alternative. See Table 4-3 for details.

6.0 Block Up Converter Overview
Teledyne Paradise Datacom SSPAs are available with various L-Band up converter
options. The primary up converter option is the Zero dBm Block Up Converter,
ZBUCTM. The ZBUC block up converter is offered in four C-Band configurations, two
Ku-Band options, and one X-Band model. See Table 6-1 for specifications on the
respective models. The ZBUC converter offers ultra low phase noise for applications
where phase noise is an overriding factor.
The type of ZBUC converter housed within your SSPA is indicated by its model
number, as shown in Figure 6-1. The example in Figure 6-1 shows a 200W C-Band
Rack Mount SSPA with Internal Reference ZBUC converter. For a full description of
the configuration matrix, refer to the 3RU Rack Mount SSPA specification sheet
(204464).
The block up converters are high performance frequency translation devices which
provide excellent phase noise and spurious performance.
The ZBUC converter utilizes Teledyne Paradise Datacom’s proprietary “Smart
Reference Technology”. Smart Reference Technology allows the system user to
change reference frequency and power level or choose internal or external reference
without requiring any system configuration. An internal ZBUC converter adds about
1.5 pounds to the overall weight of the SSPA.

Figure 6-2: Schematic, Optional Block Up Converter
The schematic of Figure 6-2 shows the electrical position of the block up converter. It
is powered from a +15 VDC supply available from the Back Plane Board Assembly.
The Block Up Converter is simply cascaded with the SSPA at the input of the amplifier.
Figure 6-3 shows the basic block diagram of the system.
It is important to remember the requirement of a 10 MHz reference oscillator when
operating an SSPA with ZBUC converter (SSPB). If the 10 MHz reference is not
present, the M&C will report a BUC alarm and the SSPA module will mute. This
ensures that no spurious or ‘off frequency’ transmission could originate from the unit.
Note: Unless the ZBUC converter has the built-in internal reference op-
tion, with no 10 MHz reference signal present on the IFL input there will
be no output signal from the SSPA.

6.2 ZBUC Converter Theory of Operation
The ZBUC converter is a low gain block up converter with a P
topology allows the system to be integrated with little impact on the general electrical
specifications of the SSPA module.
The ZBUC converter utilizes single up conversion from L-Band to the desired RF band.
The local oscillator circuits are designed to maintain the lowest possible output phase
noise. The frequency synthesizer utilizes industry leading technology which
allows for phase noise performance previously unattainable in PLL design. The typical
phase noise specification is outlined in Table 6-2.

6.3 Smart Reference Technology
Teledyne Paradise Datacom’s zBUC block up converter comes standard with smart
reference technology. Smart reference technology allows the system operator to
change external system reference frequency without any system configuration
required. The zBUC converter will automatically sense and lock to a 10 MHz or 50
MHz system reference frequency. With the internal reference option installed, the
zBUC converter will operate with no external reference applied. In the event the system operator wishes to operate on external reference, the converter will automatically
sense the presence of an external reference and switch to external reference mode.
With the internal reference option installed, the internal reference also becomes a
backup reference which will become active in the event that external system reference
is lost.
External reference is applied to the zBUC converter via the L-Band input IFL and is
routed to the frequency synthesizer using the built-in demux circuitry.
Note: The external reference option requires the system operator to pro-
vide system reference to the zBUC/SSPB. The system will not lock and
will have no output without external reference applied.
Note: Internal reference option allows for either internal or external refer-
ence operation.
6.3.1 Specifications of Internal Crystal Reference
The 10 MHz crystal reference used in the internal reference option of the zBUC
converter has the following specifications:
Frequency Stability: ≤ ± 3 • 10-8 over the temperature range –20 to +85 °C

6.5 IFL Cable Considerations
Consideration should be given to using a high quality IFL between the indoor and
outdoor equipment. The system designer must always consider the total cable loss for
a given length and also the implications of the slope of attenuation across the 950 to
1450 MHz bandwidth. Table 6-3 gives the approximate attenuation vs. frequency for a
variety of cable types.

It is recommended to use a quality grade of 50 ohm cable such as Belden 9913, 9914,
or 7733. Check the manufacturer’s technical data to make sure that the insulation is
sufficient for the particular installation including the cable’s temperature range. Also
make sure the coaxial connector from the IFL cable to the amplifier input is wrapped
with a weather sealing tape to prevent water intrusion into the coaxial cable.
