2.5.3 Switching Off Precorrector
1. Select Exciter A ATSC > Precorrection > Linear.
The Linear window opens.
2. Set Linear Correction to Off.
The linear precorrector path is deactivated.
3. Select Exciter A ATSC > Precorrection > Nonlinear.
The Nonlinear window opens.
On Input Loss For setting the behavior in the event of a defective input signal (synchro-
nization error)
– No Mute: The output signal is not suppressed (only effective with
MFN)
– Mute: The output signal is suppressed if the data rate is incorrect (rec-
ommended for SFN)
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.
