1 Operating Options
The transmitter is controlled using the R&S NetCCU800. The R&S NetCCU800 can be operated in the following ways:
– Local operation via the display and menu keys on the front panel of the R&S
NetCCU800
– Operation via the web browser
– Monitoring and control via SNMP
If the unit is operated via the web browser of a connected PC/client computer, two modes
are possible:
– Remote operation via a directly connected PC (connector on front panel)
– Remote control via a remotely connected network client (connector on rear panel)

Chapter 5 Operating
1.1.2.2 Selecting and Editing Entries
The possibility of changing settings is controlled by a user administration facility with authorization system (see the section "User Administration") and a local/remote concept which is
valid for the entire transmitter.
Local and Remote operating modes
Local means the transmitter can be configured on site. Local access is available via the display on the front panel of the R&S NetCCU800 or by PC via the local Ethernet port.
Remote means the transmitter can be configured offsite. Remote access is available via the
remote port on the transmitt e r.
Since local and remote operation are mutually exclusive, configuration work carried out onsite cannot collide with settings entered remotely. However, it is always possible to view
transmitter settings.
The Local key on the R&S NetCCU800 is used to switch b etween the local and remote operating modes.
Locked and variable settings
Depending on the user rights concerned and the type of access (local or remote access)
some or all processing parameters can be locked. These include restrictions ar ising from
the actual constellation chosen. An appropriate symbol in front of the parameter value
shows whether or not a parameter can be changed at this time.
Symbol Meaning
The present user can change the setting. A change takes effect straight away.
The present user can change the setting. For the change to take effect, a restart
of the R&S NetCCU800
The setting cannot be changed at the present time. Possible reasons:
– The user does not have the necessary rights.
– Access is via the remote port when the R&S NetCCU800 is in local mode.
– Access is local when the R&S NetCCU800 is in remote mode.
Setting is not possible in this constellation.
- none - This parameter value is for a display; it cannot be set.
a)
(and possibly the exciter
b)
) must be carried out.
c)
a) To restart the R&S NetCCU800, run the Restart command in the SW Maintenance context menu.
b) If the parameter identified in this way is a setting for the exciter (Exciter ..... menu path), the exciter must be
restarted and then the R&S NetCCU800. To restart the exciter, run the Reboot Tx command in the Tx Setup
context menü (Exciter menu).
c) The Info command from the context menu gives information on the necessary user rights among other
things.
Examples:
2098.0720.72 - 5.4 - E-2
Chapter 5 Operating
1) Setting can be changed, but the R&S NetCCU800 needs to be restarted
2) Setting can be changed; a change takes effect straight away
1) Due to insufficient user rights, the selected parameter cannot be changed at this time
2) Operation access rights are needed in order to change this setting
Selecting entries
The Edit ... selection window is displayed as soon as you click OK to confirm a field that
provides a choice.
1) The entry can be edited.
2) The entry cannot be edited (no authorization (logon) or setting not possible in this constellation)

1.4 Monitoring and Control via SNMP
SNMP (Simple Network Management Protocol) is used for monitoring and controlling a
wide variety of different units in a network. Detailed information about this topic can be
found under http://www.wikipedia.org/.
A description of the unit - the MIB (Management Inform ation Base) - must be load ed in the
central unit ("manager") from which the transmitters are monitored.
A monitored unit contains a program ( "agent") which can answer querie s from the manager
and execute commands. Furthermore, the agent may of its own accord generate a message and send it to the manager. In this way, the central unit can be informed of a fault.
1.4.1 Installation
The MIBs required for monitoring and controlling a transmitter are stored as a ZIP archive
directly in the transmitter control unit and can be downloaded from there using any networkcompatible unit. All of the information required for configuration is contained in the MIBs
themselves.
When the transmitter is put into operation, both the agent in the tr ansmitter and the manager must be configured. Additional steps may be necessary if the transmitter is connected
via routers, firewalls or similar devices as they may block data packets.
The XX8000 transmitter family supports the versions SNMPv1 and SNMPv2c.
Alarms can be sent as v1Traps, v2Traps or v2Informs.
2098.0720.72 - 5.21 - E-2
Chapter 5 Operating
Several destinations can be set for fault messages (alarm sinks).
Several communities can be set with Read Only auth orization and Rea d/Write author i-
zation.
1.4.1.1 Settings on Transmitter Side
You can make settings yourself via the local disp lay (if available), the web se rver or SNMP.
The menu windows of the SNMP menu contain all the settings tha t are required for accessing a transmitter.
Note Changes to these settings are adopted immediately. The device does not need to be re-
started.
2098.0720.72 - 5.22 - E-2
Chapter 5 Operating
Note Detailed information about the individual parameters can be found in the descriptions of the
respective menu windows.
1.4.1.2 Settings on Manager Side
To be able to monitor and control a transmitter with SNMP, the MIB of the device and a program which can interpret the MIB must be available on the manager side.
You can load all available MIBs from any device using a web browser.
1. Log on using the web browser and select the SNMP Administration menu.
MIBs from Rohde&Schwarz and IRT are available. MIBs from IRT allow transmitters to
be linked using SNMP irrespective of the manufacturer. They are, however, limited with
respect to their functionality. When using IRT MIBs, you can select the "Inhibit Status"
for local operation (in the same way as for the parallel contacts). If this function is activated, no alarms/traps are sent when the transmitter is in l ocal mo de. You can activate/
deactivate this function using Inhibit Status in the SNMP > General menu window.
The MIBs have the naming convention RS-XX8000-<TV/Radio Standard>-<Standby
Concept/Option>-MIB. An example is RS-XX8000-ATV-TX-MIB for signal transmitters
for analog TV.
Examples of MIBs and contents:
MIB Description
RS-COMMON-MIB Contains general Rohde&Schwarz definitions

2. Save the required ZIP file to your PC.
3. Load the following MIBs:
a) RS-COMMON-MIB
b) RS-XX8000-COMMON-MIB
c) MIB of the standby concept or option
A detailed description of the MIBs, the information that they cont ain and th e associated options is given below.
1.4.1.3 Testing SNMP Communication
SNMP communications is properly set up if you have loaded the MIBs in your program and
you are using the correct IP address of the transmitter and the correct commu nity. For queries and settings you must set the SNMP version in your manager; the transmitters detect
the used protocol automatically.
The following query can be used as a simple test:
In the example above, a transmitter with the IP address 10.123.10.7 queries the OID (ObjectIdentifier: unique designation of a data point) serialNumber
(.1.3.6.1.4.1.2566.127.1.2.167.1.1.1.2). The reply from the agent is 100111.
2098.0720.72 - 5.24 - E-2
Chapter 5 Operating
Using a further test, you can check whether the transmitter sends an alarm message in the
event of an error and whether this message reaches the alarm destinations. To do so, set
an OID sendTestTrap (.1.3.6.1.4.1.2566.127.1.2.167.1.1.2.3) to the value 2, which triggers
a testTrap (.1.3.6.1.4.1.2566.1 27.1.2.167.1.2.0.1). This alarm is sent to all receivers which
have been entered for the alarms (Trapsinks, see above).
This type of fault message functions in a slightly different way than that used for querying
and setting values (default: UDP Port 161 for SET/GET and UDP Port 162 for alarms).
The following illustration shows that the testTrap has been received correctly by the unit
with the serial number 100111.
Known problems
If querying the data does not work or if you do not receive an alarm, check the following:
2098.0720.72 - 5.25 - E-2
– Has the network been connected correctly? Does the SNMP connection fun ction exclu-
sively via the remote Ethernet interface of the device (R&S NetCCU800: X5 – NETLINK,
R&S Sx800/SX801: X2, R&S xLx8000: X32 – ETHERNET REMOTE)?
– Are the network settings (IP address, gateway) correct?
– Has the correct Community been entered for accessing th e manager and the transmitter
(case-sensitive)?
– Is a PC firewall blocking incoming SNMP packets?
– Has the program which receives alarms been started and correctly configured?
– In large networks: Is a router or firewall blocking the SNMP packets?
– Is message suppression (Inhibit Status in the SNMP > General menu) activated?
1.4.1.4 Configuration
This chapter provides an overview of the available properties.
RS-XX8000-COMMON-MIB
Chapter 5 Operating
This MIB contains general data that supports every unit:
– Type plate: serial number, software version, etc
– SNMP configuration: table for alarm destinations and alarm versions
– Triggering of a test trap
– Counter for counting the transmitted traps
– List of the alarm messages last transmitted
– Parameters which are used in several other MIBs
This information always applies to the instrument that is being monitored via SNMP.
RS-XX8000-DVB-TX-MIB
This MIB contains the parameters for:
– the standby concepts "single transmitter", "passive exciter standby", "active output-
stage standby" and "passive output-stage standby"
– all power classes (low-power, medium-power and high-power)
– air-cooled and liquid-cooled transmitters
Different parameters are available depending on the system being queried. For example,
cmdTxOpModeExcAutomatic (.1.3.6.1.4.1.2566.127.1.2.167.4.1.1.1.7) gives the reply
NoSuchName if you query a single transmitter since this transmitter does not have an au-
tomatic exciter function. It is easy to find out which parameters are valid by checking the
"module compliances" (e.g. under .1.3.6.1.4.1.2566.127.1.2.167.4.5.2).
Example: DVB configuration, p assive exciter standby , medium power , optional DVB recei ver module with two inputs.

Local Time Used to set the local time
The local time is the time of day or zone time applicable at the station.
Unlike universal time (UTC = universal time coordinated), there is a positive offset for time zones east of Greenwich or a negative offset for time
zones west of Greenwich.This offset is determined by the time zone and
is always a multiple of a full hour or sometimes of a half hour.
In some countries, the clock is set forward by 1 hour in summer (daylight
saving time). The time offset relative to UTC then changes correspondingly.

Chapter 5 Operating
To identify a card displayed in Serial number, highlight IdentifyStart in the column on
the right and confirm with OK.
Click the relay of the card selected, and the card can be identified via this sound.
Note If the card cannot be identified in this way, a helpful alternative is to install the cards one
after another and to identify each card as soon as it is installed, labeling it appropriately.
Each parallel remote control interface card displayed in a random row in the Serial number
column after installation must the n be assigned to a function. This is done by means of the
position number (No. column) in the row in which the card is displayed.
1. Double click the position number (No.) of the displayed card.
2. From the editor, select the position number of the row in which the desired function is
displayed (e.g. the No. next to RemoteCtrl) and click OK to confirm.
The selected parallel remote control interface card is assigned to the corresponding

3.2.1 Status Displays, Warnings, and Error Messages
When warnings and error messages occur, this usually means that transmission operation
is impaired. Different signal colors are used to distinguish the severity of an impairment or
the "quality" of the defect. The following applies:
Status display green [OK] Transmission is not impaired.
Warning yellow [W] Although the exciter is functional, external influ-
ences may impair transmission or transmission
operation.
Error message red [F] A severe error has occurred so that transmission
operation is generally not possible.
Note This type of LED signaling using colors and abbreviations (OK, W , F, etc) is identical for the
complete menu.
Indications with and without memory effect
Status displays (green) and warnings (yellow) always reflect the current status of the exciter. On the othe r hand, error messages (red) remain active even after the reason for the error
has passed or the error has been corrected. If the error has been corrected, you can reset
the error display with the RESET key.

3.4.1.1 Setting Transmitter Operating Mode
The exciter can be used in either a medium/high-power transmitter or a low-power transmitter.
2098.0720.72 - 5.75 - E-2
Chapter 5 Operating
In the first case a R&S NetCCU800 assumes control of the power amplifiers connected to
the rack controller. In the case of a low-power transmitter the amplifiers are connected to
the exciter, which also delivers the control signals.
Each version requires slightly different setup options. These can be enabled with the aid of
the Tx Mode p arameter . In th e case of low power , a fu rther distinction is made between two
single transmitter modes and two standby modes (see table).
On delivery from the factory, the Med./High Power w. NetCCU operating mode is preset
as standard. When a low- power transmitter is brought into use for the first time, its operating
mode must therefore be changed. The settings d o not take ef fect until the ex citer has been
rebooted.
Note Depending on the configuration of the instrument s concerned, it ma y no longer be possible
to operate the exciter after having changed the operating mode via R&S NetCCU800 or
NSU. This problem can be solved as follows:
a) Configure the operating mode appropriately in the R&S NetCCU800/NSU menu or b)
correct incorrect settings via the web interfac e of the exciter.

3.6.1.1 Checking Measured Data Rate
By comparing the Meas. Data Rate [bp s] and Req. Data Rate [bp s], it is possible to check
that the input buffers (FIFOs) are neither overflowing nor underflowing (both cases would
result in transmission interruptions).
Maximum data processing rate
First, all null packets are removed from the transport stream. The associated useful data
rate is measured and displayed under Measured Dat a Rate. T rouble-free operation is po ssible provided that this measurement value remains below the value for Required Data
Rate.
Note After the useful data rate has been measured, stuffing to the required data rate is per-
formed, i.e. the difference between Required Data Rate and Measured Data Rate is compensated by inserting null packets.

3.6.2 Input > Input Automatic
Setting item Description
Preselect Input Preselection of inputs
– INPUT 1: Operating input is TS 1 IN.
– INPUT 2: Operating input is TS 2 IN.
Autoswitch Activates and deactivates automatic input switchover
In the event of a failure on the active operating input, automatic switchover to the standby input takes place. The automatic switchover mode is
defined by the following parameter settings.
Priority Selects the priority mode
– EQUAL: The preselected operating input and standby input have the
same priority . Once a switchover has taken place the system does not
normally switch back to the previously faulty operating input.
– PRIO: The preselected operating input is the priority input. Once a
switchover has taken place the system switches back to the preselected operating input as soon as the signal reappears.
Check Time Forward For setting a delay time (0 to 60 s) which must elapse before the
switchover to the standby input takes place in the event of a failure on
the operating input
Check Time Back For setting a delay time (0 to 60 s) which must elapse before switching
back to the preselected operating input after switching over from the
standby input (which is no longer active)
The function has no effect if the priority mode is set to EQUAL.
On Input Loss For setting the behavior in the event of a defective input signal (synchro-
nization error)
– No Mute: The output signal is not suppressed (only effective with
MFN)
– Mute: The output signal is suppressed if the data rate is incorrect (rec-
ommended for SFN)
2098.0720.72 - 5.83 - E-2
Chapter 5 Operating
Setting item Description
Type of Loss of Input Selection:
– Warning: If the input signal fails, only a warning will be generated.
– Fault: If the input signal fails, an additional sum fault will be generated
after the time set under Fail Delay Time has elapsed. In the case of
transmitters with exciter standby, switchover to the second exciter
occurs.
Fail Delay Time For setting a delay time which must elapse after an input signal dropout
before a general fault is generated.
3.6.2.1 Automatic Input Switchover
The exciter has a circuit for automatic switchover from one input to the other following a signal failure, provided that a valid signal is present at the second input. Before a failure occurs, the preselected input is active.
The mode of this automatic switchover circuit is defined by the following factors:
– Automatic: ON or OFF (Autoswitch)
– Delay times until switchover (Check Time Forward and Check Time Back)
– Priority mode: Inputs have equal priority or the preselected input has priority (Priority)
Automatic input switchover ON/OFF
If automatic switchover is OFF, the preselected inpu t remains active even if the input signal
fails.
If automatic switchover is ON and there is a failure at the preselected input, switchover to
the associated standby input takes place.
Priority mode PRIO (input priority)
Following a switchover of the preselected input, the automatic system switches back to this
priority input as soon as a signal reappears. Switchover is delayed for the set delay times.
If the signal fails at both the operating input and the st andby input, the priority input remains
active.
Priority mode EQUAL (equal input priority)
Following a switchover of the preselected input, the standby input with the same priority remains active until the input signal fails on this input also. The automatic system switches
back to the preselected input, but only if a signal is present on it once again. Switchover is
delayed for the set delay times.
Note Selecting this operating mode keeps to a minimum the number of switchover operations
and in certain cases the number of brea ks in transm ission (in t he case of unsynchr onized
input streams).

3.6.2.2 Behavior with Defective Input Signal
The behavior in the event of a defective input signal can be influenced by the On Input
Loss switch as follows:
– Mute: The output signal of the exciter is suppressed as so on as synchronization with the
input signal (from the operating input and standby input) is no longer possible.
– No Mute: The output signal of the exciter is not suppressed even though the input signal
is defective. Only null packets are transmitted.
3.7 Precorrection Menu
Using the menu windows in the Precorrection menu, you can activa te or de activate linear
and nonlinear precorrectors individually without having to call up the precorrector GUI (see
the section "Introduction to Precorrector Operation" in the chapter "Operatin g" of the exciter
manual).
If the software option "ADE" (K05) has been acti vated, additional functions for the automatic
mode are available. The switch settings (On/Off) correspond to the related settings in the
precorrector GUI.
Menu windows
The Precorrection menu branches to the following menu windows:
– Linear: Switches linear precorrection on or of f completely; se ttings for the ADE option (if
available)
– Nonlinear: Switches nonlinear precorrection on or off completely; settings for the ADE

3.8 RF Menu
The menu windows in the RF menu are used to make the settings for frequency generation,
modulation and RF monitoring.
The menu windows
The RF menu leads to the following menu windows:
– Synthesizer: Set pilot frequency and reference frequency source
– Output: Used to enable the RF output, to activate output level control or set the level
manually, or to correct the amplitude frequency response of subsequent components
– IQ Adjust: Used to adjust the modulator
– Limiter: Used to suppress signal peaks in the output spectrum and/or baseband

Setting item Explanation
Frequency Setting of the pilot frequency
Reference Selecting the reference source for stabilization of the frequency pro-
cessing (reference frequency source). The following settings are possible:
– Internal: Operation without external reference frequency source
– External 5 MHz: Operation with external 5 MHz reference
– External 10 MHz: Operation with external 10 MHz reference
– External 1pps: Operation with external time reference (1 pps)
The same setting options can be found in the RF > Reference menu
window.
OCXO Adjust Used to adjust an internal OCXO frequency (for operating mode "Inter-
nal")
The same setting options can be found in the RF > Reference menu
window.
3.8.1.1 Reference Frequency Source
The basis for frequency generation is a 10 MHz oven-controlled crystal oscillator (OCXO).
This OCXO can be operated in different modes:
"Internal" mode
The OCXO runs in uncontrolled mode.
It obtains its control voltage via a D/A converter which can be set using the OCXO adjust
setting item. The OCXO can be adjusted via the 10 MHz MONITORING test output (front
panel of exciter).
"External 5 MHz" and "External 10 MHz" modes
The OCXO runs in controlled mode.
Due to the control, the control voltage generated by the D/A converter is adapted on an on-
going basis so that the 10 MHz frequency of the OCXO is synchronized with the externally
supplied 5 MHz or 10 MHz reference frequency.
"External 1pps" mode
The OCXO runs in controlled mode.
The 10 MHz frequency of the OCXO is synchronized with the external seconds pulse. In
this mode, for example, SFN operation is possible without separate feed of a 10 MHz reference.

Chapter 5 Operating
3.8.1.2 Holdover Mode (if reference frequency fails)
As soon as a failure of the external reference frequency is detected, the control voltage for
the OCXO is no longer modified. The result of this is that the RF generation is now based
on the stability of the OCXO.
As soon as the external reference frequency is restored, the control voltage on the OCXO
will be controlled again with the externally supplied reference frequency.
3.8.2 RF > Output
Setting item Description
RF Output Enables (On) or disables (Off) the RF output.
Regulation Activates (On) or deactivates (Off) the output level control. During trans-
mission operation, control must be enabled.
The current status of the related level adjuster is displayed as a percentage under RF > RF Monitor > AGC Exciter.
Manual RF Level Manual setting of the output level; the setting has an effect only if output
level control is deactivated.
The current status of the related level adjuster is displayed as a percentage under RF > RF Monitor > AGC Exciter.
Output Attenuation For level adaptation purposes, an integrated attenuator with a value of
3 dB, 6 dB or 9 dB can be connected. This has no influence on the level
control.
RF Slope Correction of a slope of the amplitude freq uency response in the spec-
trum for equalizing subsequent components (output stage, filter).
Modulation Slope Correction of a curvature of the amplitude frequency response in the
spectrum for equalizing subsequent components (output stage, filter).

Display Description
AGC Regulation Displays the level of the output level control
3.8.2.1 Output Level Control
The output power delivered by the exciter is set to the nominal output level of 13 dBm by
means of a controller.
For test purposes, this controller can be deactivated. The output level is then set via the
Manual RF Level control element.
Note If Manual RF Level is set too low, the RF FAIL fault will be generated.
3.8.3 RF > IQ Adjust
When the exciter is delivered, the I/Q modulator is factory-adjusted so that no custome r intervention is normally required. If a further I/Q adjustment is needed at a later time, the
menu window RF > IQ Adjust offers the associated setting options.
Note In the section "Maintenance" (exciter manual), you will find a description of how to perform
the I/Q adjustment.
The I/Q adjustment depends on the automatically selected inte rmediate frequency LO1. Accordingly, it applies only to the intermediate frequency displayed under LO1 Frequency.
Note The following table shows the relationship between the set vision carrie r freque ncy an d in-
termediate frequency LO1:
Vision carrier frequency Intermediate frequency
47 MHz fB < 510 MHz LO1 = 2160 MHz
510 MHz fB < 580 MHz LO1 = 1920 MHz
580 MHz fB < 680 MHz LO1 = 2160 MHz

Explanation
The switch offers the following options:
– Start: starts the automatic I/Q adjustment. The calculation takes
approx. 1 minute. During this time (display Calc), the RF output signal
is suppressed.
– Break: immediately stops the adjustment. The modulator must then
be adjusted again in any case.
Important: Before performing the I/Q adjustment, make sure that the
exciter has been in operation for at least 30 minutes. During adjustment,
transmitter parameters must not be changed.
The values for the actuators Bias Coarse, Bias Fine, Gain and Phase
determined during automatic I/Q adjustment are displayed under the
setting items of the same name for manual adjustment.
The values are valid only for the intermediate frequency displayed under
LO1 Frequency and can, if required, be checked and optimized with a
manual I/Q adjustment (see section "Adjustment of I/Q modulator").

Display Explanation
Auto I/Q Adjust Status display of automatic I/Q adjustment:
– In Progress: an adjustment has been started; the calculation is cur-
rently being performed.
– Adjusted: After completion of the adjustment, the display changes
from "In Progress" to "Adjusted". This status is valid until a new and
automatic I/Q adjustment is carried out. The "Adjusted" display does
not necessarily mean that the modulator is (currently still) adjusted.
– Not Adjusted: An error has occurred during the last adjustment. The
automatic I/Q adjustment has to be repeated. If the automatic I/Q
adjustment is still not functioning after several attempts, contact technical support.
LO1 Frequency Display of the intermediate frequency LO1 which is automatically set in

1 pps signal is recognized; if the 1 pps signal fails after successful
synchronization, the output signal is no longer suppressed.
– after fail delay time: The output signal is suppressed if the 1-pps sig-
nal fails for longer than the period specified at Fail Delay Time
This is the recommended setting for operation in SFN mode.
Mute on Ref. Fail For setting the behavior in SFN and MFN mode in the event of failure of
the external reference frequency source. The following settings are possible:
– off: The output signal is not suppressed.
– only at startup: the output signal is suppressed at startup until a valid
