Introduction to OperationR&S®Tx924Operating Manual 2109.9110.02 ─ 07Tip: To cancel an inadvertently selected action, slide your finger to the side awayfrom the button highlighted orange and then lift your finger off the touchscreen.3.2 Operation via BrowserThe graphical user interface (GUI) of the Tx9 transmitter series has been implementedin 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 versionTroubleshootingYou can ensure trouble‑free operation of the GUI in a browser by installing the browserand the Java VM with their default settings on a computer configured with its factorysettings.The following solutions are available if the computer settings differ from the standardinstallation 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 loginpage. Operation via Browser
Introduction to OperationR&S®Tx925Operating Manual 2109.9110.02 ─ 07Set 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 securityIn order to ensure the optimum protection against malicious software (malware), theuser 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 yourbrowser. Java offers numerous security functions:●Java security settingsThe 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 fromuntrusted websites from being started unintentionally.●Detecting a secure browserThe Java version installed on the computer should be displayed at the bottom leftcorner of the login page only after the security notice for running Java code hasbeen confirmed. If the Java version is displayed without confirming the securitynotice, then you are using an unsecured browser or an outdated version of Java onyour computer.●Detecting the right web serverThe 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 thisis not technically feasible, take additional measures to secure communicationsbetween the transmitter and browser (e.g. via a VPN).Operation via Browser

Operation System Overview
Device View DescriptionR&S®Tx941Operating Manual 2109.9110.02 ─ 07ProgramThe currently active program 1 can be switched off using the "Program 1 – ON/OFF"button.4.1.4 N+1 RedundancyThe task of the N+1 automatic function is to provide a B standby transmitter for up toeight A transmitters. This B transmitter takes over the program of an A transmitter if anA transmitter signals a fault. The output of the B transmitter is normally connected to adummy antenna. The B transmitter is connected to an antenna by the N+1 automaticfunction as soon as the B transmitter takes over the program of the A transmitter.4.1.4.1 Manual SwitchoverManual switchover of a program from an A transmitter to the B transmitter is performedby connecting the A transmitter concerned to the dummy antenna (button: To Load onthe corresponding A transmitter). As a result of this switchover, a) the A transmitterbecomes the standby transmitter for the B transmitter and b) the B transmitter is nowno longer available as the standby transmitter for other A transmitters (exception: prior-ity control).4.1.4.2 Automatic SwitchoverIf the N+1 automatic function is active and ready for operation and the A transmitter isavailable 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 theswitchover by changing its status to "changed". The user can now either acknowledgethe 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 automaticfunction to the original state and to delete the fault which caused the switchover.4.1.4.3 Configuring N+1 Automatic FunctionThe switching behavior of the N+1 automatic function with regard to checkout timesand 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 theprogram settings are to be adopted when the B transmitter operates as a standbytransmitter.Configuring Program‑Specific SettingsThe B transmitter must store all program‑specific settings of all A transmitters internallyso 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 theoutput power. The program‑specific settings are made at the A transmitters and storedusing the menu item "Save Preset" in the Task View of the A transmitter. The settings System Overview
Device View DescriptionR&S®Tx942Operating Manual 2109.9110.02 ─ 07stored for the A transmitters are synchronized with the B transmitter automatically evenif 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 SettingsAll settings which have been stored on an A transmitter as presets and synchronizedwith the B transmitter can be overwritten individually in the B transmitter. This can beused to calibrate the power test points of the B transmitter to the frequency and outputpower 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") andthen 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 istherefore recommended to overwrite the preset settings of the A transmitters at theB transmitter only for purposes of calibrating the power test points, and never to makeprogram‑specific settings directly at the B transmitter.If a setting has been inadvertently changed on the B transmitter and stored for anA transmitter, automatic synchronization can be reactivated for this setting value in thefollowing 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 functionThis setting value is now synchronized again together with all program‑specific settingvalues of the A transmitter."N+1 Automatic" parameters●Path: "Device View (Home)" > "Automatic" > "n+1 Automatic"Name Description Value range Access rightAutomatic (AutoSwitch)Used to activate the n+1 automatic function.

Before a failure occurs, the preselected input is active. The way in which thisautomatic switchover function operates is determined by the following factors:Automatic input switchover ON/OFFIf automatic switchover is OFF, the preselected input remains active even if the inputsignal 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 inputand 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 priorityremains active until the input signal fails on this input also. The automatic systemswitches 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 forthe set delay times. Transmitter

The"Switch Mode" switch is used to select whether automatic switchover to a standbyexciter is to take place once only (Single Switch) or whether a switchback is also to beperformed if the standby exciter signals a fault, but the preselected exciter is no longerfaulty (Multiple Switch).It is also possible to set a guard time which must always expire before a switchovercan take place. This prevents unwanted switchover operations resulting from brief faultevents.OperationOne 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 ontogether 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 formeasuring and monitoring purposes by pressing the "Reserve Path (on)" switch (in the"Transmitter" menu). A switchover operation causes the standby exciter to become themain exciter and vice versa.

Up to two of these inputs can be used parallel to each otherfor 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. Allavailable 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 settingsrelevant for the logical inputs can be made directly in the Device View. The two logicalinputs are available for automatic input switchover in the event of a fault along the feedpath.4.6.3.1 Configuring Physical InputsThe 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 inputsused for the redundancy of the input signal. For each logical input, you can optionallyassign a name for the fed program multiplex. This name is displayed in the transmitterand system overview screens.TS FeedEvery 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) canbe set separately for both inputs. The gross data rate and the packet length are alsodisplayed.IP FeedDepending 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 beassigned an IP address in the menu "Device View" > "Tx<n>" > "Exciter A | B" > "TaskView" > "Configure TS LAN". The two Ethernet sockets are linked to two logical IPstreams which contain additional configuration parameters. Both IP streams supportunicast and multicast streams. For multicast streams, the IP address of the multiplexerwhich makes the stream available in the network must also be specified. It is possibleto assign both logical IP streams to the same physical socket, but to specify differentmulticast 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.

Before a failure occurs, the preselected input is active. The way in which thisautomatic switchover function operates is determined by the following factors:Automatic input switchover ON/OFFIf automatic switchover is OFF, the preselected input remains active even if the inputsignal 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 inputand 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 priorityremains active until the input signal fails on this input also. The automatic systemswitches 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 forthe set delay times.Selecting this operating mode minimizes the number of switchover operations and, incertain 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. toand from the standby input, depending on which of the two logical inputs is currentlyfaulty.The "reserve" switch position ensures that switchover takes place once only. Followingswitchover, 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 overby pressing the input selector switch (Selector) and then selecting the preselectedinput.If the switch is set to "reserve", the switchback to the preselected input is suppressed.

Device View DescriptionR&S®Tx9153Operating Manual 2109.9110.02 ─ 07To operate the transmitter with an integrated GPS receiver, an appropriate softwareoption 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 highlyprecise PPS internally.To do so, the exciter only needs to be able to synchronize with aPPS once for a few seconds after it has started.If the time and frequency reference fail at the same time, Holdover Mode becomesactive. In this operating mode, the accuracy of "time of transmission" control dependson 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 increasinglyinaccurate over time, the output signal of the exciter can be switched off after a config-urable Guard Time.Special featuresWith 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 MobileIf mobile content is transmitted and a Rohde & Schwarz AEM100 EmissionMux/SFN inserter is used, the "RSMobile" synchronization type must be selected.●R&S A53If normal content is transmitted and a Rohde & Schwarz AEM100 EmissionMux/SFN inserter is used, the "RSA53" synchronization type must be selected.●A/110In the case of the standard‑conforming SFN synchronization corresponding toATSC A/110B, the "A/110" synchronization type must be selected. It contains acompatible expansion to allow use of Mobile DTV.With the synchronization types "R&S Mobile" and "A/110", a distinction is also made asto whether the time of transmission is to be synchronized primarily using data from theTCP information or using data from the dummy bytes.Setting and display of time of transmissionIn 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 staticdelay.Exciter ATSC

If several reference signals are available at the same time, automaticselection 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 crystaloscillator (OXCO).Since, in Holdover Mode, frequency control becomes increasingly inaccurate overtime, the output signal of the exciter can be switched off after a configurable GuardTime.In the case of reference signals with major fluctuations (jitter), e.g. with non‑controlledexternal 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)."Frequency Regulation" parameters●Path:"Device View (Home)" > "Tx<n>" > "Exciter" > "Frequency Regulation" > Tab"Frequency Regulation"Name Description Value range Access rightExt. 10 MHz (Input) Indicates whether an external 10 MHz reference ispresent at the REF_IN (X64) socket on the R&STCE900.No Signal,Inaccurate,OKRead onlySource (Input) The suitable signal source for the frequency referencecan be either detected automatically or preselected inthis list.

The precorrector will calculate a new precorrection curve as soon as ashoulder 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 undistortedsignal at its RF output.The precorrector can be restarted manually (Reset), making it possible to calculate abetter precorrection curve, even if the shoulder distance has not yet been undershot.The current precorrection curve is lost as a result.Adaptive linear precorrectionWith adaptive linear precorrection, limit values for amplitude (Amplitude Ripple) andgroup delay (Group Delay Ripple) must be set. The precorrector will calculate a newprecorrection curve as soon as the limit values are exceeded.The adaptive precorrection can be stopped if necessary (Adaptive Predistortion =Stop).

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 thanthat of onset point 2. The sharpness of the two onset points is determined by the slopeof 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. Thesign 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 twoonset points.No phase shift takes place for modulation of the picture signal in the area between thetwo 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 isgreater than the position of onset point 1. The characteristic in this area begins with acorrection 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 thisarea 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."Non Linear" parameters●Path:Device View (Home) > Transmitter > Exciter > Pre-Correction > Non LinearExciter ATSC

If a rack has a power drop, the switchless combiner ensuresmaximum output power at the antenna by a continuous shift of the phase angle.Operating principleThe 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 atan input, the power of the other input can be fed to the antenna without loss. If there isa partial power drop at one of the two inputs, the power dissipation in the absorber isminimized by adjusting the phase angle.CommissioningDuring commissioning, the position of the trombone has to be calibrated for differentphase angles. To do so, connect an external power meter to the absorber of theswitchless 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 thatthe 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 thatthe power dissipation at the absorber is minimal.

A description of the device must be loaded in the centralunit ("manager"; management information base (MIB)), from which the transmitters aremonitored. A monitored device contains a program ("agent") that can answer queriesfrom the manager and execute commands. Furthermore, it is possible that the agent ofits own accord generates a message (called a notification, alarm or trap) and sends itto the manager. In this way, the central unit can be informed of a fault. The MIBsrequired for monitoring and controlling a transmitter are stored as a ZIP archive inevery 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 themanager must be configured. Additional steps may be necessary if the transmitter isconnected via routers, firewalls or similar devices, as they may block data packets.5.3.1.2 Settings on Transmitter EndYou can make settings yourself via the local R&S TDU900 display (if available), via theweb 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.

Alarms canbe 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 theremote Ethernet interface (X2 – 1000 BaseT). The system or transmitter has to be setto remote to execute SET commands.5.3.1.3 Settings on Manager EndThe basic SNMP settings (port, community) on the manager end and transmitter endhave 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 transmitterthen detects this automatically. Subsequently, SNMP communications should alreadybe functioning at a basic level. System Control

Information is displayed together there.5.3.1.7 Testing the SNMP CommunicationsIn the following example, a transmitter with the IP address 172.29.12.43 queries theOID sendTestNotification (1.3.6.1.4.1.2566.127.1.2.216.2.1.3.1). The response fromthe agent is "idle(1)". Using a further test, you can check whether the transmitter sendsan alarm message in the event of an error and whether this message reaches thealarm 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). Thisalarm is sent to all receivers that have been entered for the alarms (trapsinks, seeabove). This type of error message functions in a slightly different way than that usedfor querying and setting values (default: UDP Port 161 for SET/GET and UDP Port 162for alarms).The following image shows that the testTrap has been received correctly by thetce900-100100 device (serial number 100100).
