Chapter 5 Operating2098.0594.72 - 5.41 - E-13.5.2.1 Checking the Measured Data RateThe procedures are the same as for the high priority stream.3.5.3 Input > Input AutomaticSetting item DescriptionPreselect Input For preselecting the inputs– INPUT 1: The operating input is TS 1 IN. In the case of hierarchical coding, TS 2 IN is used as a second operating input for the low prior-ity stream.– INPUT 2: The operating input is TS 3 IN. In the case of hierarchical coding, TS 4 IN is used as a second operating input for the low prior-ity stream.Autoswitch Switches the automatic input switchover on or off.In the event of a failure on the active operating input, automatic switcho-ver to the standby input takes place. The automatic switchover mode is defined by the following parameter settings.Seaml. Switching Switches seamless input switchover on or off.– ON: In the event of a failure, input switchover takes place without a break in transmission, provided the data streams are synchronized at the operating and standby inputs.– OFF: For the purpose of testing the automatic input switchover, the Seaml. Switching function can be deactivated.The function has no effect when automatic input switchover is deacti-vated.Priority Selection of the priority mode.– EQUAL: The preselected operating input and standby input have the same priority. Once a switchover has taken place there is normally no return switchover to the operating input which previously failed.– PRIOR: The preselected operating input is the priority input. Once a switchover has taken place the system switches back to the prese-lected operating input as soon as the signal reappears.
Chapter 5 Operating2098.0594.72 - 5.42 - E-13.5.3.1 Automatic Input SwitchoverThe exciter comprises a circuit for automatic switchover from one input to the other, provid-ed that a valid signal is present at the second input. Before a failure occurs, the preselectedinput 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 or Check Time Back)– Priority mode: Inputs have equal priority or the preselected input has priority (Priority)– Operating and standby inputs synchronized or not synchronized (in conjunction withSeamless Switching)Automatic input switchover ON/OFFIf automatic switchover is OFF, the preselected input remains active even if the input signalfails.If automatic switchover is ON and there is a failure at the preselected input, switchover tothe associated standby input takes place.Priority mode PRIOR (input priority)Following a switchover of the preselected input, the automatic system switches back to thispriority input as soon as a signal reappears. Switchover is delayed for the set delay times.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 operating input after switching over from the standby input (which is no longer active).The function has no effect if the priority mode is set to EQUAL.On Input Fail For setting the behavior in the event of a defective input signal (synchro-nization error)– No Mute: The output signal is not suppressed– Mute: The output signal is suppressed if the data rate is incorrect or the MIP is faulty (recommended for SFN)Display DescriptionSeamless Switching Status display for indicating whether the input streams are synchronized on the operating and standby inputs (precondition for seamless input switchover).Setting item Description
Chapter 5 Operating2098.0594.72 - 5.43 - E-1If the signal fails at both the operating input and the standby input, the priority input remainsactive.Priority mode EQUAL (equal input priority)Following a switchover of the preselected input, the standby input with the same priority re-mains active until the input signal fails on this input also. The automatic system switchesback to the preselected input, but only if a signal is present on it once again. Switchover isdelayed for the set delay times.Note Selecting this operating mode keeps to a minimum the number of switchover operationsand in certain cases the number of breaks in transmission (in the case of unsynchronizedinput streams).3.5.3.2 Behavior in the Event of a Defective Input SignalSFN modeIn the event of a defective input signal (due for example to an incorrect data rate, defectiveor missing MIP, missing or unsynchronized signal) the output signal is in effect suppressed.In this case the switch setting On Input Fail is meaningless.MFN modeThe behavior in the event of a defective input signal can be influenced by the On Input Failswitch as follows:–Mute: The output signal from the exciter is suppressed as soon as it can no longer besynchronized with the input signal (from the operating and standby inputs).–No Mute: The output signal from the exciter is not suppressed, despite a defective inputsignal. However, when this happens only null packets are transmitted.3.6 DVB Parameters MenuThe menu windows in the DVB Parameters menu can be used not only to set (and/or pre-set) the DVB transmission parameters needed for encoding and modulation, but also tocheck the settings used as well as the TPS settings signaled during transmission (TPS =Transmission Parameter Signaling).Note Providing there is a MIP (Megaframe Initialization Packet) in the transport stream, TPS in-formation can also be read out and used for configuring the DVB transmission parameters.In this case the signaled parameters may not be the same as the manually preset param-eters.The menu windowsThe DVB Parameters menu leads to the following menu windows:

Theuser interface is the means of ensuring compliance with these conditions.The available settings and the conditions they fulfill (Ö via software) are shown in the fol-lowing table:HP stream LP streamDVB bandwidth Manual: 5, 6, 7 or 8 MHz Ö via software: LP = HPIFFT length Manual: 2 k or 8 k (also 4k in the case of DVB-H)Ö via software: LP = HPGuard interval Manual: 1/4, 1/8, 1/16 or 1/32 Ö via software: LP = HPCode rate Manual: 1/2, 2/3, 3/4, 5/6 or 7/8 Manual: 1/2, 2/3, 3/4, 5/6 or 7/8Modulation mode(constellation)manual for HP + LP: 16QAM or 64QAMÖ via software: QPSK or 16QAMHierarchy Manual: α = 1, 2 or 4 Ö LP = HP
Chapter 5 Operating2098.0594.72 - 5.48 - E-1The hierarchy parameter AlphaWith hierarchical modulation, the entire information of a frequency subcarrier is interpretedas a 2-bit modulation and an additional 2-bit or 4-bit modulation. Since the 2-bit modulationmerely contains the information on the relevant quadrant in the constellation diagram, it isvery "robust" and is used for the high-priority stream. The second modulation representsthe position specification within the quadrant. With 2-bit or 4-bit (= 4 or 16 constellationpoints), it contains more precise information but is also proportionately more "sensitive" tofaults. It is therefore used for the low-priority stream.In principle: The more constellation points there are and the closer together they are, themore sensitive the modulation. This basic rule can be used to further increase the robust-ness of the HP modulation at the expense of the LP modulation. The hierarchy parameterα is used for this purpose. It is defined as the quotient of two different distances betweenadjacent constellation points. The denominator is the distance between points from differentquadrants, the numerator the distance between points from one and the same quadrant. Ahigh α value therefore always signifies a more robust modulation on the HP channel at theexpense of a more sensitive modulation on the LP channel.3.6.2 DVB Parameters > SFN DelayAll transmitters in a single-frequency network (SFN) must transmit the same information atthe same time and at the same frequency (single-frequency condition). A number of delaytimes occur prior to transmission at the antenna, defining the individual time of transmissionat the transmitter station.The SFN Delay menu window can be used to check the individual delay times. This makesit possible to check whether the single-frequency condition is met.Display DescriptionMaximum Delay Period of time between the signal leaving the play-out center (MIP inserter) and its regular transmission at the transmitting antenna. This delay is set in the MIP inserter and serves as a basis for all the transmit-ters in the SFN.Network Delay Signal propagation time between the play-out center (MIP inserter) and the exciter input. This delay depends on the transmission path used.
Chapter 5 Operating2098.0594.72 - 5.49 - E-1Processing Delay Minimum signal transit time through the exciter. This delay depends on the DVB transmission parameters.Dynamic Delay Period of time by which signal processing is artificially delayed so that the desired time of transmission is obtained.Total Delay Actual signal transit time through the exciter. This is derived from the sum of the processing delay and the dynamic delay.Tx Offset Delay The offset in time of transmission (positive or negative) sent to the MIP for the individual transmitter site, relative to the regular time of transmis-sion specified by the maximum delay. For the purpose of display and activation, the Tx Automatic must be enabled and the Tx address of the transmitter must agree (see section "Setup > DVB").If Tx offset delay and static delay are both present at the same time, their effects combine.Setting item DescriptionStatic Delay The offset in time of transmission (positive or negative) set manually for the individual transmitter site, relative to the regular time of transmission specified by the maximum delay. The static delay can be used to com-pensate for manufacturing differences between transmitter systems.If static delay and Tx offset delay are both present at the same time, their effect combines.Max Leap in Time In relation to the computed time of transmission, this is the maximum leap in time that can be corrected without a break in transmission.Default setting: 10 µsDisplay Description

The following settings are possi-ble:– Internal: Operation without an external reference frequency source.– External 5 MHz: Operation with an external 5 MHz reference.– External 10 MHz: Operation with an external 10 MHz reference.– External 1pps: Operation with an external time reference (1 pps)The same setting options can be found in the RF > Reference menu window.OCXO adjust Setting for adjusting the internal OCXO frequency (for "Internal" mode).The same setting options can be found in the RF > Reference menu window.
Chapter 5 Operating2098.0594.72 - 5.55 - E-13.8.1.1 Reference Frequency SourceThe basis for frequency generation in the exciter is a 10 MHz oven controlled crystal oscil-lator (OCXO). This OCXO can be operated in two different modes:"Internal" modeThe OCXO runs in uncontrolled mode.It obtains its control voltage via a D/A converter which can be set using the OCXO adjustitem. The frequency of the OCXO present at the 10 MHz MONITORING test output (on thefront panel of the exciter) can be adjusted to 10 MHz if necessary."External" modeThe OCXO runs in controlled mode.Due to the control, the control voltage generated by the D/A converter is adapted on an on-going basis so that the 10 MHz frequency of the OCXO is synchronized to the externallysupplied 5 MHz or 10 MHz reference frequency, or to the external 1-pps signal.3.8.1.2 Holdover Mode (In Case of Failure of the Reference Frequency)As soon as a failure of the external reference frequency is detected, the control voltage forthe OCXO is no longer modified. The result of this is that the RF generation is now basedon the stability of the OCXO.As soon as the external reference frequency is restored, the control voltage on the OCXOwill be controlled again with the externally supplied reference frequency.Display DescriptionFrequency offset Any frequency offset is added straight to the channel center frequency.The frequency offset transferred in the MIP is addressed to a particular transmitter in the network and is evaluated only if the Tx address set in the Setup > DVB menu window is the correct recipient. For the purpose of display and activation the Tx Automatic also needs to be enabled (see section "Setup > DVB").

During trans-mission operation, control must be enabled.The current status of the related level adjuster is displayed as a percent-age under RF > RF Monitor > AGC Exciter.Manual RF Level Manual setting of the output level; the setting has an effect only if output level control is deactivated.The current status of the related level adjuster is displayed as a percent-age under RF > RF Monitor > AGC Exciter.Output Attenuation For level adaptation purposes, an integrated attenuator with a value of 3 dB, 6 dB or 9 dB can be connected. This has no influence on the level control.RF Slope Correction of a slope of the amplitude frequency response in the spec-trum for equalizing subsequent components (output stage, filter).Modulation Slope Correction of a curvature of the amplitude frequency response in the spectrum for equalizing subsequent components (output stage, filter).Display DescriptionAGC Regulation Displays the level of the output level control
Chapter 5 Operating2098.0594.72 - 5.57 - E-1For test purposes this controller can be deactivated. The output level is then set via theManual RF Level control element.Note If Manual RF Level is set too low, the RF FAIL error will be generated.3.8.3 RF > IQ AdjustWhen it is delivered from the factory, the I/Q modulator is preadjusted so that no customerintervention is normally required.If you need a new I/Q adjustment at a later point in time, this will involve the use of the ac-tuators in the RF > IQ Adjust menu window. The I/Q adjustment is dependent on the automatically selected intermediate frequencyLO1. Accordingly, it applies only for the intermediate frequency displayed under LO1 Fre-quency.Note The following table shows the relationship between the set vision carrier frequency and in-termediate frequency LO1:Note For information on how to carry out a manual I/Q adjustment, see the section "Manual Ad-justment of the I/Q Modulator".Vision carrier frequency Intermediate frequency47 MHz ≤ fV < 510 MHz ⇒LO1 = 2160 MHz510 MHz ≤ fV < 580 MHz ⇒LO1 = 1920 MHz580 MHz ≤ fV < 680 MHz ⇒LO1 = 2160 MHz680 MHz ≤ fV < 860 MHz ⇒LO1 = 1920 MHzSetting item DescriptionAuto I/Q Adjust An option for automatic I/Q adjustment will be implemented in a later software release.I/Q Test Signal Switches a test signal on or off for use in performing manual I/Q adjust-ment.

Chapter 5 Operating2098.0594.72 - 5.62 - E-14 Manual Adjustment of the I/Q ModulatorNote Before performing the adjustment, make sure that the exciter has been in operation for atleast 15 minutes.ObjectiveIf quadrature modulation were optimal (theoretically possible), the residual carrier would becompletely suppressed. In actual practice however, residual carriers arise (e.g. due tocrosstalk). They must be suppressed using suitable correction carriers.The objective of I/Q adjustment is to suppress the undesired center carrier and undesiredcarrier in the sideband with respect to a test carrier by better than 70 dB.Preparation and test carrier measurement1. Call up the exciter menu with RF > IQ Adjust.2. Use the I/Q Test Signal switch to turn on the test signal.3.
