1 Information about this Manual
This manual is part of the documentation for the R&S THU9 transmitter family from
Rohde & Schwarz. The individual manuals for the transmitter family have a modular
structure and complement each other.
Structure
The system manual, which is the central and overarching part of the overall documen-
tation, describes all the steps involved in installing a transmitter.
Operation of the transmitter system after installation and the steps required to put the
system into operation are described in the operating manual.
The service manual describes all maintenance, troubleshooting and service tasks that
customers can carry out themselves. At certain points in the transmitter manual, the
reader is referred to the appropriate operating manual or service manual.
Contents
The manuals for the transmitter family describe all activities required for installation,
startup, operation, maintenance, troubleshooting and servicing of the transmitter and
its component parts. The appendix contains the interface descriptions and the techni-
cal documentation.
Safety
All skilled personnel working with a transmitter or its components have a duty to read
the associated manuals and to follow the safety measures described in the section
"Safety" and given at appropriate points in the manual. It must be ensured that the
transmitter and the individual components of the transmitter are used only for their
intended use. All activities connected with the transmitter or individual transmitter com-
ponents must be carried out by skilled personnel. If activities require additional skills
and qualifications, this is indicated at the appropriate points in the manual.
Symbols and notation
The "warning triangle" symbol refers the reader to potential hazards. The degree of
danger is indicated by different signal words next to the warning symbol.
Instructions are given in numbered steps. All other formatting options are intended to
improve clarity and are self‑explanatory.
Introduction to Operation
R&S®Tx9

3 Introduction to Operation
The R&S TDU900 is a display unit with a touchscreen function and a graphical user
interface for configuring Tx9 transmitter systems.
3.1 Operation via R&S TDU900
3.1.1 Opening Display
When in the idle state, the display is inside the R&S TDU900 operating unit.
1. Unlock the display by pressing firmly on the trapezoidal area.
2. The display slowly slides forward out of the instrument.
3. Tilt the display until you have reached the most ergonomically comfortable angle
for operation.
3.1.2 Closing Display
1. Tilt the display to a horizontal position until you feel the display engage.
2. Push the display all the way into the R&S TDU900 housing until the display
engages in the transport lock.
3. The display illumination automatically switches off in this state.
Tip: Close the operating unit during long periods of inactivity to prolong the service
life of the backlighting.
3.1.3 Using Touchscreen Function
The display has a touchscreen function for operating all of the transmitter functions.
Using sharp‑edged objects can damage or destroy the surface. Therefore only use
your finger to operate the touchscreen.
1. A light touch on a button is enough to trigger a user action.
2. A button lights up orange for as long as your finger remains there. The action is not
carried out until you remove your finger from the button.

Tip: To cancel an inadvertently selected action, slide your finger to the side away
from the button highlighted orange and then lift your finger off the touchscreen.
3.2 Operation via Browser
The graphical user interface (GUI) of the Tx9 transmitter series has been implemented
in JAVA to ensure optimum user experience. Java technology provides maximum com-
patibility between different versions of operating systems and browsers.
Supported operating systems
●Windows XP, Windows Vista (32 bit version)
●Windows 7 (32 bit and 64 bit version)
●Windows 8 (32 bit and 64 bit version)
Supported browsers
●Google Chrome
●Mozilla Firefox
●Internet Explorer 7
●Internet Explorer 8
●Internet Explorer 9 (32 bit version)
●Internet Explorer 10 (32 bit and 64 bit desktop version)
Supported JAVA virtual machines
●Oracle (previously: Sun) JRE 7 in 32 bit version
Troubleshooting
You can ensure trouble‑free operation of the GUI in a browser by installing the browser
and the Java VM with their default settings on a computer configured with its factory
settings.
The following solutions are available if the computer settings differ from the standard
installation and there are problems:
●The 64 bit version of Internet Explorer 9 is not supported
–The 32 bit version, which is also installed, must be used
– Use another browser, such as Google Chrome or Mozilla Firefox.
●Internet Explorer 10 is to be used on a 64 bit operating system (Windows 7/8):
"Enhanced Protection Mode" must be disabled in the browser under "Tools >
Options > Advanced" (this is the default setting).
●Windows 8 Modern UI (previously: Metro) does not support Java.
– Start the desktop version of Internet Explorer 10 from the desktop.
– Start Google Chrome or Firefox from a link in Modern UI.
●The error message "Application blocked by security settings" appears on the login
page.
Operation via Browser
Introduction to Operation
R&S®Tx9
25Operating Manual 2109.9110.02 ─ 07
Set the security level to "High" in the Java Control Panel and restart the browser.
●Only a 64 bit Java runtime environment (JRE) is installed.
Remove the 64 bit JRE and install the 32 bit version.
●A 64 bit JRE is installed and required by another application (unlikely)
Install a 32 bit JRE to run in parallel with the 64 bit version.
You can determine the Java version (32 or 64 bit) as follows:
●Open an input prompt window (Start > Run > Open, insert "cmd" and press <OK>)
●Enter: java -d32 -version
●The version number is shown if a 32 bit JRE is installed, otherwise an error mes-
sage appears.
Java security
In order to ensure the optimum protection against malicious software (malware), the
user interface for the Tx9 transmitter series has been implemented in Java. Java tech-
nology eliminates the need to run potentially unsafe ActiveX or Flash plug‑ins in your
browser. Java offers numerous security functions:
●Java security settings
The security level in the Java Control Panel should be set to "High". A correspond-
ing security warning appears then appears when opening a website with Java con-
tents; you have to acknowledge this message. This prevents Java programs from
untrusted websites from being started unintentionally.
●Detecting a secure browser
The Java version installed on the computer should be displayed at the bottom left
corner of the login page only after the security notice for running Java code has
been confirmed. If the Java version is displayed without confirming the security
notice, then you are using an unsecured browser or an outdated version of Java on
your computer.
●Detecting the right web server
The security notice for running the Java code shows the IP address of the transmit-
ter that loaded the Java code to the browser.
Transmitters in the Tx9 series are protected against malware by various security meas-
ures. Nevertheless, it is important to follow this general information on security to pro-
tect other computers in the same network against malware:
●Always keep your browser updated to the latest version!
●Always update your Java runtime environment to the most recent version immedi-
ately after starting your browser.
●Avoid using unsecured browsers, such as MS Internet Explorer 7.
●Always use a firewall to display Internet pages from servers outside your LAN.
●The transmitter should be accessible within its protected intranet at all times. If this
is not technically feasible, take additional measures to secure communications
between the transmitter and browser (e.g. via a VPN).

Program
The currently active program 1 can be switched off using the "Program 1 – ON/OFF"
button.
4.1.4 N+1 Redundancy
The task of the N+1 automatic function is to provide a B standby transmitter for up to
eight A transmitters. This B transmitter takes over the program of an A transmitter if an
A transmitter signals a fault. The output of the B transmitter is normally connected to a
dummy antenna. The B transmitter is connected to an antenna by the N+1 automatic
function as soon as the B transmitter takes over the program of the A transmitter.
4.1.4.1 Manual Switchover
Manual switchover of a program from an A transmitter to the B transmitter is performed
by connecting the A transmitter concerned to the dummy antenna (button: To Load on
the corresponding A transmitter). As a result of this switchover, a) the A transmitter
becomes the standby transmitter for the B transmitter and b) the B transmitter is now
no longer available as the standby transmitter for other A transmitters (exception: prior-
ity control).
4.1.4.2 Automatic Switchover
If the N+1 automatic function is active and ready for operation and the A transmitter is
available for the N+1 automatic function, a fault in the A transmitter causes the pro-
gram to switch over to the B transmitter. The N+1 automatic function signals the
switchover by changing its status to "changed". The user can now either acknowledge
the switchover by pressing the "Accept changeover" key and adopt it as the new oper-
ating state, or attempt by pressing the "Reset Faults" key to reset the N+1 automatic
function to the original state and to delete the fault which caused the switchover.
4.1.4.3 Configuring N+1 Automatic Function
The switching behavior of the N+1 automatic function with regard to checkout times
and automatic switchback can be configured according to individual requirements. Fur-
thermore, for the B transmitter it is possible to define the A transmitter from which the
program settings are to be adopted when the B transmitter operates as a standby
transmitter.
Configuring Program‑Specific Settings
The B transmitter must store all program‑specific settings of all A transmitters internally
so that they can be activated immediately in the event of a fault. Program‑specific set-
tings are all settings which directly affect the signal path through the transmitter, i.e.
settings for the coder, the exciter inputs and outputs, the transmit frequency and the
output power. The program‑specific settings are made at the A transmitters and stored
using the menu item "Save Preset" in the Task View of the A transmitter. The settings
System Overview
Device View Description
R&S®Tx9
42Operating Manual 2109.9110.02 ─ 07
stored for the A transmitters are synchronized with the B transmitter automatically even
if the B transmitter was switched off when the settings were stored. If the program‑spe-
cific settings are changed at A transmitters without these settings being stored as pre-
sets, the changes will not be available on the B transmitter in the event of a switchover.
Presets can only be stored on the A transmitters.
Configuring Power‑Specific Settings
All settings which have been stored on an A transmitter as presets and synchronized
with the B transmitter can be overwritten individually in the B transmitter. This can be
used to calibrate the power test points of the B transmitter to the frequency and output
power of the respective A transmitter. To do so, the "Program Settings" of the A trans-
mitter concerned must be activated in the B transmitter ("Load Program Settings") and
then the corresponding settings must be made in the menus of the B transmitter.
Finally, the changed settings must be stored in the B transmitter ("Save Tx B Set-
tings"). This must be repeated for all programs that the B transmitter can take over.
Settings that have been changed directly at the B transmitter are no longer synchron-
ized with the B transmitter using the "Save Preset" function on the A transmitters. It is
therefore recommended to overwrite the preset settings of the A transmitters at the
B transmitter only for purposes of calibrating the power test points, and never to make
program‑specific settings directly at the B transmitter.
If a setting has been inadvertently changed on the B transmitter and stored for an
A transmitter, automatic synchronization can be reactivated for this setting value in the
following way:
●On the B transmitter, set the setting value to the same value as on the A transmit-
ter.
●Press "Save Tx B Settings" in the menu of the N+1 automatic function
This setting value is now synchronized again together with all program‑specific setting
values of the A transmitter.

4.2.1 Automatic Switchover
4.2.1.1 Automatic Input Signal
The R&S®TCE900 in the R&S®TCE900 exciter configuration has an automatic switch-
over function which, in the event of a signal failure at one logical input, switches over to
the other logical input (provided that a valid input signal is available at the other logical
input). Before a failure occurs, the preselected input is active. The way in which this
automatic switchover function operates is determined by the following factors:
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 standby input takes place.
Input priority (Preferred Input = Logical Input 1/2)
Following switchover of the priority logical input to the standby input, the automatic sys-
tem switches back to this priority input as soon as a signal returns. All switchover oper-
ations are delayed for the set delay times. If the signal fails at both the operating input
and the standby input, the priority input always remains active.
Inputs with equal priority (Preferred Input = none)
Following switchover of the active logical input, the second 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
(and if "Switch to" is set to "reserve & back"). All switchover operations are delayed for
the set delay times.
Transmitter
Device View Description
R&S®Tx9
45Operating Manual 2109.9110.02 ─ 07
Selecting this operating mode minimizes the number of switchover operations and, in
certain cases, the number of breaks in transmission.
Direction of switchover (Switch to)
The "to reserve and back" switch position enables switchover in both directions, i.e. to
and from the standby input, depending on which of the two logical inputs is currently
faulty.
The "reserve" switch position ensures that switchover takes place once only. Following
switchover, the automatic system switches to "switched" and the "Active" indicator dis-
appears.
Switchback to the preselected input takes place when the active input is switched over
by pressing the input selector switch (Selector) and then selecting the preselected
input.
If the switch is set to "reserve", the switchback to the preselected input is suppressed.
Manual switchover between inputs
The input can be switched over in the "Home" > "Transmitter" > "Exciter" menu by
pressing the input selector switch ("Selector") and then selecting the desired input.
Depending on the configuration and switching state (ON/OFF) of the automatic input
signal switchover function, this menu contains either the switch used to change the
preferred input or the switch used to switch over the active input.
The automatic input signal switchover function is configured in the following way:
1. Navigate to the following destination using the menu bar:
"Devices" > "Tx<n>" > "Exciter A|B" > "Input Auto"

4.2.1.2 Automatic Exciter Switchover
The automatic exciter switchover function enables a faulty exciter to be automatically
switched over to a functional standby exciter.
In the "Exciter Automatic" menu it is possible to switch automatic switchover between
two exciters on and off and to select the basic operating behavior of the function. The
"Switch Mode" switch is used to select whether automatic switchover to a standby
exciter is to take place once only (Single Switch) or whether a switchback is also to be
performed if the standby exciter signals a fault, but the preselected exciter is no longer
faulty (Multiple Switch).
It is also possible to set a guard time which must always expire before a switchover
can take place. This prevents unwanted switchover operations resulting from brief fault
events.
Operation
One of the two exciters can be preselected for operation by pressing the exciter selec-
tor switch (or via the ExciterAuto -> Exciter Switch tab). This exciter is switched on
together with the output stage by pressing the "Program Path On" switch (in the
"Transmitter" menu). If necessary, the RF of the standby exciter can be switched on for
measuring and monitoring purposes by pressing the "Reserve Path (on)" switch (in the
"Transmitter" menu). A switchover operation causes the standby exciter to become the
main exciter and vice versa. The ON/OFF switches then act on the other exciter in
each case.
"Single Switch" Mode
If a fault occurs in the preselected exciter, the automatic switchover function will swap
the main and standby exciter and display an "Automatic changed" message.
Either the new state can now be accepted by changing the "preselected exciter"
("Automatic changed" disappears) or the automatic switchover function can be reset to
its original state by pressing "Reset Faults" (in the "Transmitter" menu).

"Multiple Switch" Mode
This mode is identical to "Single Switch", except that following a double switchover
operation the "preselected" exciter becomes the active exciter again. The "Automatic
Changed" message is still displayed in this case. To delete this message, either the
new state of the automatic switchover can be adopted by pressing the "Recommand
Selection" button (in the "Transmitter" > "Exciter Auto" menu, "Exciter Switch" tab) or
the original state can be assumed again by pressing "Reset Faults" (in the Transmitter

4.6.2 Setting Transmit Frequency and Output Power
The transmit frequency is configured separately for each R&S TCE900 exciter with an
accuracy of ±1 Hz. For the DVB‑T and DVB‑T2 transmission standards, the channel
center frequency must be set during this process.
The output power of the R&S TCE900 exciters is regulated internally to +13 dBm for
DTV. It can be attenuated via an integrated attenuator by up to 9 dB (in steps of 3 dB).
Depending on the number of amplifiers that a transmitter has, the attenuator in the
R&S TCE900 exciter has to be configured as described below.
The transmit frequency and output power are configured in the following way:
► Navigate to the following using the menu bar:

4.6.3 Signal Feed
The TCE900 Exciter has a number of physical inputs depending on the modules and
software options installed. Up to two of these inputs can be used parallel to each other
for signal feed. They are referred to below as logical inputs. The assignment of physi-
cal inputs to logical inputs takes place in a special task during startup of the system. All
available physical inputs can also be configured within this task. In normal operation,
the two selected logical inputs are visible in the Device View of the exciter. All settings
relevant for the logical inputs can be made directly in the Device View. The two logical
inputs are available for automatic input switchover in the event of a fault along the feed
path.
4.6.3.1 Configuring Physical Inputs
The physical inputs are configured at startup of the system in the menu "Device View"
> "Tx<n>" > "Exciter A | B" > "Task View" > "Configure Inputs".
This function allows you to define two logical inputs from the number of available inputs
used for the redundancy of the input signal. For each logical input, you can optionally
assign a name for the fed program multiplex. This name is displayed in the transmitter
and system overview screens.
TS Feed
Every TCE900 Exciter which is suitable for the transmission of digital TV has two trans-
port stream inputs (connector X20 and X21). The data format (ASI/SMPTE/Auto) can
be set separately for both inputs. The gross data rate and the packet length are also
displayed.
IP Feed
Depending on the installed software options, up to two independent IP feeds are avail-
able in the TCE900 Exciter. During startup, each Ethernet socket (X30, X31) must be
assigned an IP address in the menu "Device View" > "Tx<n>" > "Exciter A | B" > "Task
View" > "Configure TS LAN". The two Ethernet sockets are linked to two logical IP
streams which contain additional configuration parameters. Both IP streams support
unicast and multicast streams. For multicast streams, the IP address of the multiplexer
which makes the stream available in the network must also be specified. It is possible
to assign both logical IP streams to the same physical socket, but to specify different
multicast addresses. This provides maximum flexibility with regard to different redun-
dancy scenarios in the feed path.
The IP addresses for the Ethernet sockets are configured in the "Configure TS LAN"
task and only become effective after the TCE900 Exciter has been restarted.

4.6.3.2 Input Signal Switchover
The R&S®TCE900 in the R&S®TCE900 Exciter configuration has an automatic switch-
over function which, in the event of a signal failure at one logical input, switches over to
the other logical input (provided that a valid input signal is available at the other logical
input). Before a failure occurs, the preselected input is active. The way in which this
automatic switchover function operates is determined by the following factors:
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 standby input takes place.
Input priority (Preferred Input = Logical Input 1/2)
Following switchover of the priority logical input to the standby input, the automatic sys-
tem switches back to this priority input as soon as a signal returns. All switchover oper-
ations are delayed for the set delay times. If the signal fails at both the operating input
and the standby input, the priority input always remains active.
Inputs with equal priority (Preferred Input = none)
Following switchover of the active logical input, the second 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
(and if "Switch to" is set to "reserve & back"). All switchover operations are delayed for
the set delay times.
Selecting this operating mode minimizes the number of switchover operations and, in
certain cases, the number of breaks in transmission.
Direction of switchover (Switch to)
The "reserve and back" switch position enables switchover in both directions, i.e. to
and from the standby input, depending on which of the two logical inputs is currently
faulty.
The "reserve" switch position ensures that switchover takes place once only. Following
switchover, the automatic system switches to "switched" and the "Active" indicator dis-
appears.
Switchback to the preselected input takes place when the active input is switched over
by pressing the input selector switch (Selector) and then selecting the preselected
input.
If the switch is set to "reserve", the switchback to the preselected input is suppressed.

Seamless switching
The automatic input signal switchover function has an operating mode which permits
seamless switching between two inputs. Seamless switching is activated using the
"Seamless" switch. If seamless switching is possible, the switchover always takes
place immediately, irrespective of the set guard times. Seamless switching is available
without restriction for operation in single‑frequency networks (SFN). For operation in
MFNs, it is necessary to set the maximum expected delay time between the two signal
feeds. The signal which arrives earlier is delayed by the set time and the signal which
arrives later is adjusted to the earlier signal. The currently measured delay between the
two inputs is displayed to provide an adjustment aid. In SFN and MFN mode, signals
can be fed via two different media (e.g. ASI and IP).
Manual switchover between inputs
Manual switchover is possible when the automatic input signal switchover function is
both on and off.
●Switchover with automatic input signal switchover OFF
The input can be switched over in the "Home" > "Transmitter" > "Exciter" menu by
pressing the input selector switch ("Selector") and then selecting the desired input
"Selected Input".
●Switchover with automatic input signal switchover ON
The input can be switched over in the "Home" > "Transmitter" > "Exciter" menu by
pressing the input selector switch ("Selector") and then selecting the desired input
"Selected Input" if the two inputs are configured with equal priority (Preferred Input
= None).
If one of the inputs is configured as having priority, switchover is performed by
changing the priority input "Preferred Input" in the same menu.

4.6.4 Controlling Time of Transmission in Single-Frequency Networks
(SFN)
For operation in single-frequency networks (SFN), the R&S®TCE900 exciter has a
function which allows the time at which the signal is transmitted to be controlled. In the
SFN, time synchronization of all exciters in the network is performed using a seconds
pulse (PPS), which is generally obtained at the exciter site via GPS satellites.
Controlling time of transmission
Control of the time of transmission is switched on and off in the "Device View (Home)"
> "Transmitter" > "Exciter" > "SFN Regulation" menu ("Time Synchronization" tab) by
means of the "SFN Sync" switch (On (SFN) / Off (MFN)). This function can only be
used if the exciter has a time reference.
Exciter ATSC
Device View Description
R&S®Tx9
153Operating Manual 2109.9110.02 ─ 07
To operate the transmitter with an integrated GPS receiver, an appropriate software
option must be activated using an option code.
The following options are available:
●Feed of an external PPS signal (pulse per second)
●Use of an integrated GPS receiver (requires option key)
If the time reference fails during operation, the exciter can revert to its integrated fre-
quency control function (see the chapter "Frequency Control") and calculate a highly
precise PPS internally.To do so, the exciter only needs to be able to synchronize with a
PPS once for a few seconds after it has started.
If the time and frequency reference fail at the same time, Holdover Mode becomes
active. In this operating mode, the accuracy of "time of transmission" control depends
on the frequency stability of the integrated, temperature‑stabilized 10 MHz crystal oscil-
lator (OXCO).
Since, in Holdover Mode, calculation of the time of transmission becomes increasingly
inaccurate over time, the output signal of the exciter can be switched off after a config-
urable Guard Time.
Special features
With ATSC, up to three different synchronization types are supported.
An appropriate software option must be activated using an option code for the respec-
tive synchronization type.
●R&S Mobile
If mobile content is transmitted and a Rohde & Schwarz AEM100 Emission
Mux/SFN inserter is used, the "RSMobile" synchronization type must be selected.
●R&S A53
If normal content is transmitted and a Rohde & Schwarz AEM100 Emission
Mux/SFN inserter is used, the "RSA53" synchronization type must be selected.
●A/110
In the case of the standard‑conforming SFN synchronization corresponding to
ATSC A/110B, the "A/110" synchronization type must be selected. It contains a
compatible expansion to allow use of Mobile DTV.
With the synchronization types "R&S Mobile" and "A/110", a distinction is also made as
to whether the time of transmission is to be synchronized primarily using data from the
TCP information or using data from the dummy bytes.
Setting and display of time of transmission
In the "Device View (Home)" > "Transmitter" > "Exciter" > "SFN Regulation" menu
("SFN Delay" tab), the time of transmission is displayed relative to the reference time.
The time of transmission can be adapted individually by setting an additional static
delay.
Exciter ATSC
Device View Description
R&S®Tx9
154Operating Manual 2109.9110.02 ─ 07
The following delays occur:
●Maximum Delay
Time taken for the signal to travel from the playout center (MIP inserter) to the
transmit antenna for regular transmission. This delay is set in the SFN adapter and
is the default for all transmitters of the SFN.
●Network Delay
Time taken for the signal to travel from the playout center (SFN adapter) to the
input of the exciter. With IP feed, the time for forward error correction (FEC) and
packet reordering is added to the Network Delay. This delay depends on the used
transmission path.
●Processing Delay
Minimum transit time of the signal through the exciter. This delay depends on the
set transmission parameters.
●Dynamic Delay
Period of time by which signal processing is delayed artificially in order to achieve
the desired time of transmission.
●Total Delay
Actual transit time of the signal through the exciter. This time is the sum of Pro-
cessing Delay plus Dynamic Delay.
●Static SFN Delay
Positive or negative offset (set manually for the individual transmitter location) of
the time of transmission relative to the regular time of transmission preset under
Maximum Delay. The Static SFN Delay is used to compensate for differences
between transmission systems from different manufacturers.
●Dispatch Time
This is the actual time of transmission. It is the network‑wide Maximum Delay plus
the transmitter‑specific Static SFN Delay.

4.6.5 Using Frequency Control
The R&S TCE900 in the R&S TCE900 exciter configuration has a transmit frequency
control function.
Depending on the accuracy and stability requirements, one of two operating modes
can be selected for the transmitter.
To operate the transmitter with an integrated GPS receiver, an appropriate software
option must be activated using an option code.
●Free‑wheeling mode
Here the transmit frequency is formed from a temperature‑stabilized 10 MHz crys-
tal oscillator (TCXO).
The frequency stability is sufficient for continuous operation in multiple frequency
networks (MFN).
Exciter ATSC
Device View Description
R&S®Tx9
158Operating Manual 2109.9110.02 ─ 07
●Operation with reference frequency
Here the transit frequency is stabilized by means of a reference frequency. The fol-
lowing options are available:
–External 10 MHz reference frequency
– External PPS (pulse per second)
– Built-in GPS receiver.
The frequency stability and frequency accuracy which can be achieved in this way
fulfill the increased requirements for operation of the transmitter in single‑frequency
networks. If several reference signals are available at the same time, automatic
selection of the most suitable reference frequency is possible.
If the reference signal fails, the transmitter switches over to Holdover Mode and fre-
quency control operates with the accuracy of the temperature‑stabilized 10 MHz crystal
oscillator (OXCO).
Since, in Holdover Mode, frequency control becomes increasingly inaccurate over
time, the output signal of the exciter can be switched off after a configurable Guard
Time.
In the case of reference signals with major fluctuations (jitter), e.g. with non‑controlled
external GPS receivers, a jitter correction function can be activated.
For measuring purposes, the used reference signal or one of the reference signals pro-
cessed internally in the exciter can be output via the Monitor-Out socket (X24).

4.6.6 Precorrection
Each R&S®TCE900 Exciter is equipped with an adaptive precorrector, which continu-
ously compensates for nonlinear distortions of the amplifiers and linear distortions of
the output filter so that, in both cases, a high‑quality signal is present at the output of
the transmitter.
Adaptive nonlinear precorrection
For adaptive nonlinear precorrection, enter a minimum shoulder distance that must not
be undershot. The precorrector will calculate a new precorrection curve as soon as a
shoulder distance below the set value is measured.
The adaptive precorrection can be stopped if necessary (Adaptive Predistortion =
Stop). The current precorrection curve remains in effect.
For measuring purposes, the adaptive nonlinear precorrector can be bypassed (Adap-
tive Predistortion = Bypass) so that the R&S®TCE900 Exciter returns an undistorted
signal at its RF output.
The precorrector can be restarted manually (Reset), making it possible to calculate a
better precorrection curve, even if the shoulder distance has not yet been undershot.
The current precorrection curve is lost as a result.
Adaptive linear precorrection
With adaptive linear precorrection, limit values for amplitude (Amplitude Ripple) and
group delay (Group Delay Ripple) must be set. The precorrector will calculate a new
precorrection curve as soon as the limit values are exceeded.
The adaptive precorrection can be stopped if necessary (Adaptive Predistortion =
Stop). The current precorrection curve remains in effect.
For measuring purposes, the adaptive linear precorrector can be bypassed (Adaptive
Predistortion = Bypass) so that the R&S®TCE900 Exciter returns an undistorted signal
at its RF output.
The precorrector can be restarted manually (Reset), making it possible to calculate a
better precorrection curve, even if the shoulder distance has not yet been undershot.
The current precorrection curve is lost as a result.
The adaptive adjustment of nonlinear precorrection is not available for analog TV
standards.
Crest factor reduction
Available as an option for all COFDM standards
The crest factor feature provides the possibility of improving the signal parameters
"MER" and "Shoulder Distance" separately. Additionally, the signal can be improved
and the DC supply voltage reduced at the amplifier to increase efficiency; this simulta-
neously reduces the crest factor of the transmitter.

Sound phase shifter
Only available for analog TV standards
The sound phase shifter modifies the phase of the sound subcarrier as a function of
the low-frequency modulation of the picture signal.
When the sound phase shifter is switched on, its characteristic is determined using two
onset points.
The reference for setting the position is initially a value of 37.5 % for the back porch.
Smaller values are in the range of the sync pulse, whereby a value of 15 % corre-
sponds to a sync‑pulse amplitude of 300 mV. Larger values are in the picture range,
whereby a value of 90 % corresponds to a picture amplitude of 700 mV.
An additional condition is that the setting for onset point 1 must always be greater than
that of onset point 2. The sharpness of the two onset points is determined by the slope
of the characteristic at these points. The magnitude of the setting determines the mag-
nitude of the phase shift, whereby a setting of 50 % specifies the maximum value. The
sign of the setting value determines whether the phase is shifted in the positive or neg-
ative direction.
When the characteristic is calculated, it is divided into three linear areas by the two
onset points.
No phase shift takes place for modulation of the picture signal in the area between the
two onset points, i.e. a correction phase of 0° is set.
A correction phase unequal to 0° is set in the case of picture signal modulation which is
greater than the position of onset point 1. The characteristic in this area begins with a
correction phase of 0°, with modulation corresponding to the position of onset point 1,
and increases linearly up to the maximum phase set with slope 1, with 100 % modula-
tion of the picture signal.
Similarly, a correction phase unequal to 0° is also set in the case of picture signal mod-
ulation which is smaller than the position of onset point 2. The characteristic in this
area begins with a correction phase of 0°, with modulation corresponding to the posi-
tion of onset point 2, and increases linearly up to the maximum phase set with slope 2,
with 0 % modulation of the picture signal.

4.11 Switchless Combiner
The switchless combiner couples the RF output signals of two racks and feeds the total
power to the antenna. If a rack has a power drop, the switchless combiner ensures
maximum output power at the antenna by a continuous shift of the phase angle.
Operating principle
The switchless combiner consists of two 90-degree couplers and an RF tube of varia-
ble length (referred to as a trombone). Changing the length makes it possible to gener-
ate a variable phase shift between the two inputs. If there is a complete power drop at
an input, the power of the other input can be fed to the antenna without loss. If there is
a partial power drop at one of the two inputs, the power dissipation in the absorber is
minimized by adjusting the phase angle.
Commissioning
During commissioning, the position of the trombone has to be calibrated for different
phase angles. To do so, connect an external power meter to the absorber of the
switchless combiner.
The calibration process consists of the following work steps:
●Start the calibration process.
●Set the switchless combiner to "local".
●Switch the signal of input 1 off.
●Press the up/down buttons on the switchless combiner to set the trombone so that
the power dissipation at the absorber is minimal.
●Press "Save Position".
●Switch the signal of input 1 on and of input 2 off.
●Press the up/down buttons on the switchless combiner to set the trombone so that
the power dissipation at the absorber is minimal.

●Press "Save Position" again.
●Switch the signal of input 2 back on.
●End the calibration process and set the switchless combiner to "remote".
Finally, use the phase shifter in rack 2 to set a power maximum at the antenna.
The calibration process has to be carried out again after changing the frequency. In
addition, the switchless combiner has to be reprogrammed beforehand according to
the manufacturer's instructions.
Operation
In "Automatic" mode, the switchless combiner responds to power losses at its inputs
independently. In "Manual" mode, one of three fixed positions of the trombone can be
moved to, for example, to switch off a rack.

Antifreeze Used to define whether or not the fans at the heat exchanger
are to switch off if the temperature drops well below the speci-
fied temperature. Off: The fans switch off. This setting is recom-
mended in order to reduce the energy consumption of the cool-
ing system. On: The fans continue to run even at low outside
temperatures. This setting is recommended if the risk of fan
seizure due to freezing is to be reduced. Note: Even if anti-
freeze mode is active, the condensation protection function of
the transmitter will still switch off the fans at an inlet tempera-
ture below approx. +10 °C. The fans are designed in such a
way that they are not damaged if they seize up due to freezing.

5.3 System Control
5.3.1 Simple Network Management Protocol (SNMP)
To operate the transmitter in SNMP mode, an appropriate software option must be
activated using an option key.
5.3.1.1 General
Simple network management protocol (SNMP) is used for monitoring and controlling
different devices in a network. A description of the device must be loaded in the central
unit ("manager"; management information base (MIB)), from which the transmitters are
monitored. A monitored device contains a program ("agent") that can answer queries
from the manager and execute commands. Furthermore, it is possible that the agent of
its own accord generates a message (called a notification, alarm or trap) and sends it
to the manager. In this way, the central unit can be informed of a fault. The MIBs
required for monitoring and controlling a transmitter are stored as a ZIP archive in
every R&S TCE900. From there, they can be downloaded with any web browser.
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.
5.3.1.2 Settings on Transmitter End
You can make settings yourself via the local R&S TDU900 display (if available), via the
web server or in part via SNMP. The Task View > System Control > SNMP menu con-
tains all the settings that are required for accessing a transmitter.
Changes to these settings are adopted immediately. The device does not need to be
restarted.

230Operating Manual 2109.9110.02 ─ 07
Fig. 5-1: SNMP menu
The XX9 transmitter family supports the versions SNMPv1 and SNMPv2c. Alarms can
be sent as v1Traps, v2Traps or v2Informs. Several destinations for error messages
(trapsinks) and several communities can be set with read only authorization and read/
write authorization. SNMP is a protocol for remote control and is offered only at the
remote Ethernet interface (X2 – 1000 BaseT). The system or transmitter has to be set
to remote to execute SET commands.
5.3.1.3 Settings on Manager End
The basic SNMP settings (port, community) on the manager end and transmitter end
have must match. You typically define these settings for each IP address in your pro-
gram (e.g. MIB browser). The SNMP version is also set in the manager; the transmitter
then detects this automatically. Subsequently, SNMP communications should already
be functioning at a basic level.

Fig. 5-2: SNMP manager settings
Being able to monitor and control a transmitter with SNMP requires the device's MIB
on the manager end and a program that can interpret the MIB. You can load all availa-
ble MIBs from any device using a web browser.
●Log in using the WebGUI and select the menu Task View > System Control >

–RS-COMMON-MIB
– RS-XX9-SMI-MIB and RS-XX9-TC-MIB
– RS-XX9-COMMON-MIB
– MIB of the standby concept, standard or option
A detailed description of the MIBs, the information that they contain and the associated
options is given below.
MIBs from Rohde & Schwarz and the Munich-based Broadcast Technology Institute
(IRT) are available. MIBs from IRT allow transmitters to be linked using SNMP irre-
spective of the manufacturer. They are, however, limited with respect to their function-
ality. Some particular features to keep in mind when using IRT MIBs are listed in the
document "SoftwareMiniSpecification – SNMP for XX9".
The MIBs have the naming convention RS-XX9-<TV/radio standard>-<function/
option>-MIB. Examples include: RS-XX9-DVBT2-MIB for DVB-T2 and RS-XX9-AIR-
COOLING-MIB for air cooling.

The device can be queried by SNMP in order to find out which MIBs have been imple-
mented. This information is contained in the table "sysORTable"
(OID .iso(1).org(3).dod(6).internet(1).mgmt(2).mib-2(1).system(1).sysORTable(9) of
the SNMPv2 MIB). There is a corresponding MIB for each type of modulation.

with internal Rohde & Schwarz cooling or with (external) station cool-
ing.
RS-XX9-MTX-MIB This MIB contains parameters independent of the type of modulation

RS-XX9-FM-MIB This MIB contains parameters for FM signal processing.
RS-XX9-ISDBT-MIB This MIB contains parameters for ISDBT signal processing.
5.3.1.5 Which OIDs from a MIB Must Be Used?
Different parameters are available depending on the system being queried. For exam-
ple, txExcAutoOperationMode (in RS-XX9-TX-MIB) returns the response NoSuch-
Name when you query a single transmitter, since it has no automatic exciter switch-
over. It is easy to find out which parameters are valid by checking the conformance
statements. In the example for automatic exciter switchover above, the OID txExcAu-
toOperationMode is contained in the txObjsExciterAutomatic object group.

For N+1 systems this also means that unavailable parameters may receive the
response NoSuchName, e.g. parameters from the transmitter A8 if only a 4+1 system
is present.

5.3.1.6 Setting Alarms
Parameters that allow configuration of the transmitter alarms can be found under the
OID "commonSnmpConfiguration". For example, it is possible to switch off the IRT
alarms (factory default setting: on) and to switch on Rohde & Schwarz alarms (factory
default setting: off). The transmitter-specific alarms offer an extensive range of configu-
ration possibilities. In addition, it is also possible to assign a user-selectable priority
and to check the current status. Since the Rohde & Schwarz MIBs contain a large
number of alarms, three predefined groups for faults, warnings and information exist, to
System Control
Task View Description
R&S®Tx9
235Operating Manual 2109.9110.02 ─ 07
which all alarms are assigned. For each alarm, the respective alarm class is given in
the binding AlarmClass.
A possible and recommended configuration would therefore be to disable the IRT
alarms and to enable the Rohde & Schwarz alarms of the fault class:
●irtNotificationsAllOff: OID 1.3.6.1.4.1.2566.127.1.2.216.2.1.3.3.0
●rsNotificationsAllFaultsOn; OID 1.3.6.1.4.1.2566.127.1.2.216.2.1.3.6.0
The example shows alarm class fault (1) for the alarm "txSummaryFault" (transmitter
sum fault).
Alarms are always collected in the Notifications branch in the MIBs. They always have
at least three bindings.
●Alarm Class: Predefined, fixed alarm class
●Priority: User-selectable priority
●State: Current state of the alarm
"State" is defined in NotificationState in the MIB RS-XX9-TC-MIB:
undefined(1) State is not available
off(2) Alarm is inactive or not available
fault(3) Alarm corresponds to an error
warning(4) Alarm corresponds to a warning
ok(5) Alarm does not correspond to either an error or a warning or alarm is OK
Matching the alarms, there are one or more notification tables in the MIBs on the
Objects branch. Information is displayed together there.
5.3.1.7 Testing the SNMP Communications
In the following example, a transmitter with the IP address 172.29.12.43 queries the
OID sendTestNotification (1.3.6.1.4.1.2566.127.1.2.216.2.1.3.1). The response from
the agent is "idle(1)". 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 sendTestNotification to the value of 2 (trig-
ger), which triggers a commonTest trap (1.3.6.1.4.1.2566.127.1.2.216.2.0.1000). This
alarm is sent to all receivers that have been entered for the alarms (trapsinks, see
above). This type of error 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 image shows that the testTrap has been received correctly by the
tce900-100100 device (serial number 100100).

●Integration of the R&S TCE900 in the transmitter system
Depending on their function, some R&S TCE900 units require additional informa-
tion regarding:
–system variant (MultiTX, N+1)
– transmitter variant (Redundancy, Modulation, Amplifier Type)
– assignment to a transmitter (TX Number, Exciter A/B)
●Physical structure of the transmitter system
Depending on their function, some R&S TCE900 units require additional informa-
tion regarding:
– total number of transmitter racks
– number of racks per transmitter
●Physical installation location of the R&S TCE900 units
Each R&S TCE900 must be assigned the following:
– number of the rack in which the R&S TCE900 is installed
– number of the installation slot within a rack
●Assignment of transmitters to racks ("Racks" menu tab)
