3. The upper Waveguide (flexible arm) along with the isolator bracket should be installed next.

4. Complete the installation by attaching the coaxial cables, coaxial load, and control cables.

5. Note that the installation of the control cables determines which unit will function as the backup SSPA. Due to the nature of the dual WG-coax switch, this will always be the upper unit. Therefore, the end of the redundant loop cable (40, Figure 2-1) labeled “BU SSPA,” should be connected to J4 of the upper (back-up) unit.

6. The appropriate end of the control cable attaching to the Waveguide switch (50) should also be attached to the backup unit (J7).

Redundancy kits with all the cabling and switches for a 1:2 configuration also are available, and are usually designed to a particular customer’s specifications. Contact Comtech EFData for 1:2 redundancy kits and installati on diagram s.

This chapter describes the instructions for SSPA redundancy configurations.

4.1 General

All Comtech EFData SSPAs are designed to operate in both stand-alone and redundant configurations. Every SSPA contains the circuitry and logic necessary to perform all the functions of a backup controller in both a 1:1 and 1:2 configuration. This includes the ability to monitor and control up to two RF waveguide switch assemblies. In addition, the SSPA has been designed to automatically detect whether it is in a stand-alone or redundancy system. These features greatly simplify redundancy configurations from both the cost and operational complexity standpoint.

CHAPTER 4.

REDUNDANT

CONFIGURATION

4.2 Redundancy Operation

Refer to Figure 2-1 for a full installation diagram of a typical redundant system.

In normal operation, incoming RF signals are routed through the primary online SSPA (1:1 configuration), or SSPA(s) (1:2 configuration), to the system output(s) by the combination waveguide/coax switch(es).

With the backup SSPA in the controller mode, it monitors the online unit(s) for faults. When a fault occurs in an online unit, the backup SSPA automatically configures itself with the settings of the faulted online unit. (These now-active settings also incorporate any user defined offsets that may have been programmed into the backup unit.)

Rev. 0 4-1

Redundant Configuration KPA080 Ku-Band Solid-State Power Amplifier

Figure 4-1. Control Cabling of a 1:1 System

The position of the waveguide/coax switch also is automatically changed to route the signal through the backup unit, thereby minimizing the loss of traffic.

Control cable assemblies are required to set up either a 1:1 or a 1:2 system (other RF coaxial cables and waveguides are required as shown in Figure 2-1).

Figure 4-1 shows the control cabling for a 1:1 system. The redundant loop cable connecting the two SSPAs together provides a number of functions.

• This cable assembly is not a straight through cable. The cable assembly is labeled “backup” on one end, and SSPA #1 on the

•

other end. The cable assembly is wired so that when connected to two SSPAs, one

•

SSPA will automatically configure itself as the Backup Controller and the other SSPA will automatically configure itself as the ‘Primary SSPA’.

The backup SSPA communicates to the primary SSPA via a serial interface also provided by this redundant loop cable assembly. This interface is used by the Backup SSPA to acquire configuration information from SSPA #1. In addition, this interface provides the link for virtual addressing as described in Section 5 of this manual.

Summary fault relay contacts also are included in this cable assembly and are used by the backup SSPA as an input to its switching logic. The second cable assembly is a six-wire assembly between the backup SSPA and the Waveguide Switch Assembly. Figure 4-2 shows the cabling for a 1:2 system. Note that the functionality describes for the 1:1 cable assembly is directly applicable for the 1:2 cable assembly. The only difference is that there is now a third connector daisy-chained onto the cable assembly.

This connector is labeled SSPA #2. When connected to a Comtech EFData SSPA, the SSPA will automatically configure itself as Primary SSPA #2.

The second control cable attaches from the Backup Unit J7 to the Waveguide switch.

4.2.1 Gain Equalization of Redundant Units

Typical procedures to equalize the gain between the Backup Unit and the Online Unit(s) via the Gain Offset adjustment in the backup unit’s CONFIGURATION Menu are as follows:

Note:

Make sure all connections are made as outlined previously in Sections 2 and 4.)

Determine the relative gain of the Backup Unit vs the Online unit(s).

Rev. 0 4-3

Redundant Configuration KPA080 Ku-Band Solid-State Power Amplifier

Make sure the Online Unit is “online” and transmitting. This can be verified through the Configuration Menu, and the front panel LEDs.

1. Apply an RF signal to the RF redundancy input isolator. Monitor the output power level at the waveguide switch output. (Make sure not to apply too large of an input signal which will saturate the amplifiers. Also be sure to have a properly rated load to measure the output power.)

3. Adjust the input signal power level and attenuation of the Online Unit to arrive at the desired output power level.

4. Record the output level of the Online Unit in dBm.

5. Force the backup unit to be the active path as outlined in the CONFIGURATION Menu. Ensure the Offset Value at this point is 0.0 dBm. Record the output level in dBm of the back-up unit.

6. If the output levels are equal, no more adjustment is necessary. Otherwise

proceed as follows.

4-4 Rev. 0

KPA080 Ku-Band Solid-State Power Amplifier Redundant Configuration

Case 1. Backup < Online unit(s).

1. Ensure the online unit attenuation is set to a value in dB greater than or equal (

)

≥

to the difference in levels measured above.

2. With the backup unit forced to be the active unit, adjust the Offset Value in the CONFIGURATION Menu to approximately the difference measured above. This will be a (-) negative

number.

3. Toggle between the online and backup units as being the active path by forcing and un-forcing a back-up through the back-up unit CONFIGURATION Menu settings. Ensure the output levels measured are equal. If necessary, re-adjust the Offset Value until equal levels are measured. (Note that the back-up unit total attenuation level as now indicated in the CONFIGURATION Menu will be equal to the setting of the online unit less

the Offset Value.)

For Example:

Online Unit Output Level Backup Unit Output Level Backup Unit Offset Value Online Attenuation Setting AFTER TOGGLING AND ADJUSTING: Backup Offset Value New Equaliz ed Output Level Backup Attenuation Setting

-1.75 dB

47.0 dBm

1.25 dB (3+(-1.75)=1.25)

Case 2. Backup > Online unit(s).

1. With the backup unit forced to be the active unit, adjust the Offset Value in the CONFIGURATION Menu to roughly the difference measured above. This will be a (+) positive

number.

2. Toggle between the online and backup units as being the active path by forcing and un-forcing a back-up through the back-up unit CONFIGURATION Menu settings. Make sure the output levels measured are equal. If necessary, re-adjust the Offset Value until equal levels are measured. (Note that the back-up unit total attenuation level as now indicated in the CONFIGURATION Menu will be equal to the setting of the online unit plus

the Offset Value.)

For Example:

Online Unit Output Level Backup Unit Output Level Backup Unit Offset Value Online attenuation setting AFTER TOGGLING AND ADJUSTING: Backup Offset Value New Equaliz ed Output Level Backup Attenuation Setting

= 47.00 dBm = 48.75 dBm = 0.00 dBm = 3.0 dBm

This chapter describes the instructions for SSPA remote control operation through a serial port. Primary SSPAs in a redundancy subsystem also can be indirectly controlled through the backup SSPA using virtual addressing. All SSPA configuration parameters as well as all monitor and status information is available via the remote port.

5.1 General

Chapter 5.

REMOTE CONTROL

SPECIFICATION

The backup SSPA in the redundancy subsystem automatically monitors the configuration and status for each of the primary (chained) SSPAs. This information is communicated via the dedicated serial interface between the SSPAs.

If a primary SSPA fails, the backup detects this event and automatically

•

reconfigures itself to the proper attenuation setting and positions the waveguide switch to provide minimal loss of traffic.

A result of this design is to greatly lessen the throughput requirements (i.e. polling rate) of earth station monitor and control systems. The backup SSPA handles all of the time critical tasks allowing the earth station monitor and control system to focus on less intelligent subsystems.

5.4 Cables

EIA-232

The remote control port is configured with pin 2 as the TX data signal (TD) and pin 3 as the RX data signal. This arrangement allows straight connection (pin 2 to pin 2 and pin 3 to pin 3) between the SSPA and most standard serial ports using any standard EIA-232 cable (i.e. no need to swap pins 2 and 3).

EIA-485

EIA-485 cabling can be implemented with a single ribbon cable using IDC Mass Terminated style connectors or with discrete wires using solder-cup style connectors. A sufficient length of ribbon cable must be allowed to reach the system monitor and control computer.

EIA-485

2-wire

4-wire

The Comtech EFData SSPA does not require the hardware handshaking provided by the DSR, RTS, and CTS signals. These signals are provided for customers that are using int erface t erminals that require this handshaking. Most of today’s PC’s are provided with EIA-232 serial ports that do not require the hardware handshaking. In these instances, the interface can be reduced t o t hree signals; TD, RD, and GND.

Both 2-wire and 4-wire applications are supported. The 4-wire interface provides independent sign al wires for each of the RX (+RX) signal and its complement (-RX) as well as the TX (+TX) signal and its complement (-TX). In the 2-wire interface, the RX signal and the TX signal (+RX/TX) share one wire and likewise the complemen t signals (-RX/TX) share one wire. Choice of 2-wire vs 4-wire is based on the cu stomer’s interface equipment and the cabling between this equipment and the SSPA(s).

Each signal pair (+RX/TX and –RX/TX) is provided on two pins. This is done to provide customers who are using solder-cup type DB-9 connector the ability to more easily daisy chain the signals to multiple devices while maintaining one wire per solder-cup. Customers who use IDC Mass Terminated style DB-9 connectors (Ribbon cabl e t ypes) n eed only use three signals.

All five signals are required.

5.5 Protocol

Refer to Table 5-1 for protocol description. Protocol is divided into six subjects:

• Transmission Mode

Baud Rate

•

Format

•

Character Set

•

Response Timeout

•

Bus Inactivity Requirements

•

Table 5-1. Protocol Description

Transmission Mode

Baud Rate

Character Set

Response Timeout

Bus Inactivity Requirement

The transmission mode is half-duplex implemented in Command/Response convention. This method requires the external system monitor and control unit to initiate all communications by command and the SSPA to respond with either confirmation or an error message. The confirmation may contain status information.

The default serial port Baud Rate is 9600. Baud rates of 4800, 2400, 1200, and 300 also are supported.

The character set implemented is ASCII.

A minimum of 500 milliseconds should be provided before declaring a No Reponse instance, at which time the command should be re-transmitted.

COMTECH EFData recommends that a minimum of 50 milliseconds bus inactivity be provided by the user between the receipt of a response from an addressed SSPA and issuing the next command on the serial bus.

5.5.1 Format

The following parameters are the default character format:

Start Bit Parity Bit Stop Bits Data Bits

An optional character format that can be selected is:

5.6 Access Methods

The SSPA may be accessed directly by using a physical address or indirectly through a backup SSPA in a redundant configuration using a virtual address.

5.6.1 Direct Access

SSPAs may be directly accessed by the EIA-232 interface or by the EIA-485 interface in a buss configuration.

EIA-485

EIA-232

In this control network, the SSPA is paralleled on a common EIA-485 cable, and has a unique physical address. Only one EIA-485 port is required on the system's monitor and control computer.

For EIA-232 control, a direct E IA-232 cable connection is made t o each SSPA to be accessed. If an external Mon itor and Control Computer is used, one EI A-232 port per SSPA is required.

5.6.2 Indirect Access

SSPAs in Redundancy Mode may be addressed indirectly by adding a virtual address to the backup SSPA’s physical address. The virtual address corresponds to the SSPA’s position in the redundant subsystem. The backup SSPA recognizes the virtual address and executes the command via the dedicated serial link between itself and the targeted SSPA. This addressing mode is provided to reduce cabinet wiring complexity by allowing remote access to either both SSPAs (in a 1:1 redundant subsystem) or all three SSPAs (in a 1:2 redundant subsystem) using a single EIA-232 or EIA-485 connection to the backup SSPA.

Note:

Due to memory limitations, virtual addressing is not 1:2 system. Contact the factory for specific information. Virtual addressing is fully functional in a KPA080 1:1 system.

fully functional in a KPA080

Rev. 0 5-5

Remote Control KPA080 Ku-Band Solid-State Power Amplifier

5.7 Addressess

All SSPAs are addressed in a command by the Device Address. The Device Address consists of a physical address or a physical address plus a virtual address.

5.7.1 Physical Address

Each SSPA in the system must have a unique physical address regardless of the access method used. The physical address consists of a string of 1, 2 or 3 numbers from 1 to

256. The physical address is entered into a SSPA via the front panel. For Direct Access, the physical address is the only address required to command a SSPA. A backup SSPA or a stand-alone SSPA can only be accessed with a physical address.

For Example: 10 Addresses SSPA whose physical address is 10 .

5.7.2 Virtual Address

In order to access an SSPA controlled by a backup SSPA indirectly, a virtual address is required. A virtual address is appended to the physical address of the backup SSPA with a “V”. The virtual address is either the number “1" or “2" corresponding to the SSPA’s designation in a redundant subsystem .

For Example: 10V2 Addresses second SSPA in a 1:2

redundant subsystem controlled by the backup SSPA whose physical address is 10.

5.7.3 Message Structure

The structure of either a Command, Response, or Error Message is as follows:

Start Character

•

Device Address

•

Command or Response

•

End of Message String

•

5.7.4 Start Character

The Start Character begins each message:

For Example: < Start of a user Command. > Start of a SSPA response.

5.7.5 Device Address

The Device Address consists of a Physical Address. For this document DEV is used for the generic case examples.

For Example; <10 direct addre ssi ng <10V2 indirect addressing

5.7.6 Command

A Command is a variable length character string beginning with a / and containing either an instruction or an instruction and data for an SSPA to act upon.

If data is passed by command, it is appended to the instruction by an

•

underscore( _ ).

If data is retrieved by command, underscore follows the instruction flagging

•

the SSPA to supply data in a response.

In this document /COM is used for the generic case examples.

•

For Example: <DEV/COM_xxx'cr' Sends data to an SSPA.

For Example: <DEV/COM_'cr' Requests information from an

SSPA.

5.8 Confirmation Response

A confirmation will change the start character, and echo the Device Address and Command. Any requested data will be appended to the Command.

For Example: >DEV/COM_xxx'cr''lf']

5.8.1 Error Response

If an SSPA cannot execute a Command or detects a protocol violation, an error response is generated. An error is flagged by changing the "/" command designator in the response to a "?". Following the "?" error symbol are two characters which are unique error symbols useful for computer analysis. The two error symbols are followed by a text string explaining the error for the convenience of a human operator. For this document ER is used for the generic case examples response.

For Example: >DEV?COM ER Error Message 'cr''lf']

5.8.2 End Of Message

End of message strings were devised in such a way that an orderly screen presentation would result when SSPAs are controlled by simple ASCII terminals.

5.8.2.1 Command Ending

The end of message for a command is a carriage return. For this document 'cr' is used for the carriage return.

For Example: <DEV/COM'cr'

5.8.2.2 Response Ending

End of message for a response is a carriage return, line feed and a bracket: 'cr''lf'].

For Example: >DEV/COM'cr''lf']

Where: y = A for Auto M for Manual

The default is Off. This command provides for automatic

switching by the backup SSPA if both units are in the Redundancy Mode. This command is only accepted by the backup SSPA. If a primary SSPA is set in Manual Mode and a fault occurs, the backup SSPA will log the occurrence and not act upon further information from the SSPA until put into Automatic Mode.

Where: x = 1 or 2 SSPA number. Y = F to force a backup N = to remove a backup zzzzz = NONE, if no backup active. ACTIVE, if an automatic backup has occurred. FORCED, if a forced backup is active.

This command allows the user to force a backup condition for mainternace and test purposes. This command must be sent to the SSPA designated as the backup SSPA to configure the Waveguide switch to a position such that the backup SSPA is Online and the primary SSPA is Offline.

Where x = 1 or 2 This command allows the user to assign

prority when operating in a 1:2 redundant subsystem. This command provides arbitration in the event that both primary SSPAs are faulted simulataneously.

Maintenance and Troubleshooting KPA080 Ku-Band Solid-State Power Amplifier

6.2 Maintenance Testing

The SSPA is a Ku-Band SSPA with an RF output level of +48.5 dBm at 1 dB compression.

6.2.1 Test Point Samples

The RF input and output can be monitored at the RF Sample Test Points on the front panel. Type N connectors are provided. The sample RF input level is -20 dBc nominal, and the RF output level is -40 dBc nominal. Actual measured data for these sample ports is located on the front panel.

6.3 Troubleshooting

Refer to Table 6-1.

SSPA operating problems can be identified by first observing the status indicators on the front panel. When a fault condition is indicated, the specific fault, or faults, can be identified in the Current Faults Function Menu (Chapter 3) which is accessed through the local operation keypad and displayed on the LCD display located on the front panel. The status of SSPA functions is displayed in the Monitor Status Functions Menu.

Refer to Section 3, Operation, for a description of the SSPA command functions; also, check the status of the mute condition in the configuration menu (i.e.: Mute = “On” means that the amplifier will be muted.)

3. Check output of 28 VDC power supply. Remove and replace 28V power supply.

At power-up, the fans are sequenced on. In Normal operation, the second fan does not turn on until 3 seconds (approximately) after the first fan.

1. Check AS/0206 PCB to ensure the connections at P4 and P5 are not loose.

2. Check cable connection at the fans. There should be 24 VDC (approximately) between the two pins at the fan.

3. Check cable wiring if fautly or return to factor y fo r re p a i r.

Maintenance and Troubleshooting KPA080 Ku-Band Solid-State Power Amplifier

Table 6-1. Troubleshooting (Continued)

Symptom Possible Ca use Solution

No RF output or ≤ output level.

Failed SSPA amplifier module.

No remote control communication

1. Mute fuction activated.

2. Amplification = Off feature activated.

3. Large customer attenuation values selected.

4. Input power level not correct.

5. Faulty input connections from 9V supplies.

6. Fault SSPA control cable or connection .

This can usually be determined by using the Monitor menu to check the DC current levels being drawn by each transistor inside the amplifier module. Any transitor (QX) current that is 50% more or less than normal would probably indicate a failure.

1. Incorrect cable connections.

2. Improper communication settings between SSPA and controlling terminal.

3. Entry mode of unit set to LOCAL.

1. Check the configuration menu to determine if mute functions has been activated. Mute = On Means that the unit is muted. Turn Mute feature to Off to allow RF amplification of the input signal.

2. The amplification = Off feature allows for lower currect draw from the prome power source under standby conditions. To obtain RF output, ensure that this feature is set to amplification = On.

3. Check the Attenuation = XX setting in the configuration menu. Lower value to get more gain.

4. Use the input sample port on the front panel to determine that the input power level is as specified. Remove and repl ace the input cable.

5. Use the Monitor menu to check the internal level of the PS1 and PS2. The levels should be near 9V. If not correct, use a voltmeter to measure the voltage where the #8 wires enter the amplifier unit. With Unit Off, tighten connections if necessary.

6. Check the 25-pin ribb on cable connection at the amplifier module and at AS/0200 PCB. Tighten as necessary.

Nominal Values:

Q1 = 20mA Q2 = 100 mA Q3, Q4 = 1.0 A Q5, Q6, Q7 = 2.0 A Q8 to Q19 = 2.25 A Q20 to Q27 = 5.5 A

There are no user serviceable parts in si de the amplifier module. Return to factory for repair.

1. Ensure cable is connected prop erly. Check settings of SSPA along with remote

control terminal software.

3. Change entry mode setting in Configuration menu to Remote.

2. Excessive current draw from transistor inside amplifier module.

3. Faulty power supply.

1. Faulty wiring or connections.

2. Improper settings.

1. Do not exceed 50°C (122°F) ambient input air temperature.

2. Remove obvstructions to ensure adequate air flow and proper amplifier cooling.

3. Check fan operation. Remove and replace fan(s) as required.

4. Use Monitor menu to check transistor currents. Compare readings with th e specified nominal values. Report excessive readings to the manufacturer for repair. There are no user serviceable parts inside the SSPA amplifier module.

1. Check cable and connections from PS1 and PS2 to amplifier module. On outside of module, measure voltage. Reading should be = 9.0 ± 0.5 VDC.

2. Use Monitor menus to check transistor currents. Record excessive valu es and return entire unit to manufacturer for repair.

3. Return failed power supply for repair. Replace with the new power supply.

1. Ensure that the RF and cont rol cables are connected. Poor RF performances would tend to indicate a faulty SSPA cable/connector. a. Improper switch control would indicate

a problem with the contro l cab les.

b. Ensure the ends of the cables labeled

backup are connected to the backup unit.

2. Check redundancy setup in Configuration menu.
