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)

Note
Different entry screens and menus are displayed depending on whether the R&S
NetCCU800 is used as a NetCCU (transmitter control) or as an NCU/NSU (control of lowpower transmitters / control of n+1 systems).
This is how you navigate within the menu system:
1. Press the MENU key.
The menu is called.
Note
When you access the menu system for the first time, you are logged on by default under
the user ID Operation which authorizes you to make settings that directly affect transmitter operation.
2. Select the required menu and confirm with OK.
The overview for the selected menu is then opened (here NetCCU).

1.1.2.2
Operating
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 onsite. 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 transmitter.
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 between 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 arising 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 a) (and possibly the exciter b)) must be carried out.
The setting cannot be changed at the present time. Possible reasons:
– The user does not have the necessary rights. c)
– 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) 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.

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)

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 Information Base) - must be loaded in the
central unit ("manager") from which the transmitters are monitored.
A monitored unit contains a program ("agent") which can answer queries 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 transmitter 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.

You can make settings yourself via the local display (if available), the web server or SNMP.
The menu windows of the SNMP menu contain all the settings that are required for accessing a transmitter.
Note

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 local mode. You can activate/
deactivate this function using Inhibit Status in the SNMP > General menu window.
The MIBs have the naming convention RS-XX8000---MIB. An example is RS-XX8000-ATV-TX-MIB for signal transmitters
for analog TV.
Examples of MIBs and contents:
2098.0720.72

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 community. 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
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 (.1.3.6.1.4.1.2566.127.1.2.167.1.2.0.1). 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

– Are the network settings (IP address, gateway) correct?
– Has the correct Community been entered for accessing the 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
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 outputstage 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 automatic 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, passive exciter standby, medium power, optional DVB receiver module with two inputs.

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

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 then be assigned to a function. This is done by means of the

RF Probe Antenna Menu
You can use the RF Probe Antenna menu to enter and read off the measurement values
for the transmitter system, standby system and output power.
2.7.1
RF Probe Forward Menu Window
In the RF Probe Forward menu window you can define the nominal values for the output
power and determine the lowest level of deviation at which fault messages are to be output.
Two test points are available for measuring the RF power (RF Probe Forward and RF Probe
Reflection). Each test point has two RF rectifiers so that you can measure both the forward
and reflected power. The forward power is always measured using the first test point (RF
Probe Forward).
In the R&S NetCCU800 status screen, the forward power (Forward) is displayed in the lefthand window and the reflected power (Reflection) in the right-hand window on the basis of
the values entered here.

nominal value
Timeout RF Fail Control
Used to select the time that the lower threshold for the forward power
(specified as the RF Fail Limit) must be violated for before a fault message is output. For example, if a value of 3 dB has been entered as the
RF Fail Limit and the actual value drops below that level for 8 seconds
(typical setting for Timeout for RF Fail Control), a fault message will be
output.

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:
Note
Status display
green [OK]
Transmission is not impaired.
Warning
yellow [W]
Although the exciter is functional, external influences may impair transmission or transmission
operation.
Error message
red [F]
A severe error has occurred so that transmission
operation is generally not possible.
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 other 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.

– Low Power N+1: Operation in an N+1 standby system for low-power
transmitters with an R&S NetCCU800 switchover unit (NSU) as the
higher-level switching unit and operator station
– Single Low Power: Operation in a low-power transmitter; operated via
a connected PC and web browser
In order to switch between two transmitter operating modes, the exciter
must be rebooted a). The associated user interface is loaded.

Setting Transmitter Operating Mode
The exciter can be used in either a medium/high-power transmitter or a low-power transmitter.

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 parameter. In the case of low power, a further 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 do not take effect until the exciter has been
rebooted.1
Note
Depending on the configuration of the instruments concerned, it may 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 interface of the exciter.
3.4.2
Setup > Option Keys Submenu
Certain features of the device are activated using the Option Keys mechanism.
Each available software option can be enabled by installing a valid activation key. If a software option is later no longer required, activation can be canceled again by installing a deactivation key.
Note
The deactivation mechanism allows software options which are no longer required to be
"returned" to Rohde & Schwarz.
Option keys are available from your local Rohde & Schwarz sales partners.
Installing option keys
Option keys can be installed in three ways:
– Automatic installation of one or more activation keys using the Software Distributor
The procedure is the same as for performing software updates (see the chapter "Maintenance").
– Installation of an option key by means of a web browser
With this method, the option key can be transferred from, for example, a received mail
using the copy/paste function.
– Installation of an option key directly at the display
With this method, a 30-digit code is entered using the keyboard.
The two last methods use the installation menu Setup > Option Keys > Install described

– AUTO: Auto is selected and there is no data stream
Checking Measured Data Rate
By comparing the Meas. Data Rate [bps] and Req. Data Rate [bps], 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 Data Rate. Trouble-free operation is possible provided that this measurement value remains below the value for Required Data
Rate.
Note
2098.0720.72
After the useful data rate has been measured, stuffing to the required data rate is performed, i.e. the difference between Required Data Rate and Measured Data Rate is compensated by inserting null packets.

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.

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.
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 input 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 standby 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
2098.0720.72
Selecting this operating mode keeps to a minimum the number of switchover operations
and in certain cases the number of breaks in transmission (in the case of unsynchronized
input streams).

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 soon 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.

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 ongoing 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.

Holdover Mode (if reference frequency fails)
As soon as a failure of the external reference frequency is detected, the control voltage for

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.

Adjustment of I/Q Modulator
Note
Before performing the adjustment, make sure that the exciter has been in operation for at
least 30 minutes.
Objective
If quadrature modulation were optimal (theoretically possible), the residual carrier would be
completely suppressed. In actual practice, however, residual carriers arise (e.g. due to
crosstalk). They must be suppressed using suitable correction carriers.
The objective of I/Q adjustment is to suppress the undesired center carrier and undesired
carrier in the sideband with respect to a test carrier by better than 60 dB.
Two methods are available
Two methods are available to perform the I/Q adjustment: setting and testing actuators
manually or via a convenient automatic process.
The automatic method will usually meet the requirements. Yet, it may sometimes be useful
to test the automatically determined values for the actuators and to improve them.

Rack Setup > Rack x > Amplifier Order Menu Window
After the transmitter system has been put into operation, entries for the amplifiers (of a particular rack) are displayed in the menu path for the output stage with consecutive numbering
(Amplifier 1 to max. Amplifier 4). Since the numbering is derived from the chronological
sequence in which the amplifiers can be detected on the CAN bus, it does not always correspond to the sequence in which the amplifiers are physically arranged from top (= 1) to
bottom (= n) in the rack.
The Amplifier Order menu window is used to change the menu items for the amplifiers with
respect to the installation positions in the rack.
