Spectral Inversion
This function allows inversion of the spectrum generated in IF and RF. As the IF
spectrum is by itself inverted compared to the RF output, the inversion applied is
related to the RF output. The possible options are:
OFF Carriers with lower indices occupy the lower frequencies of the RF
channel.
ON Carriers with higher indices occupy the lower frequencies of the RF
channel.
PRBS bits
Selection of the length in bits of the internally generated pseudorandom sequences:
23 PRBS sequences of length 2
15 PRBS sequences of length 2
TS sync mode
In MFN mode, this selects the mode of operation of the modulator with respect
to the incoming TS (see Section 1.2 for further details):
Master The bit rate of the input TS must be lower than the useful bit rate for the
choice of DVB-T parameters in use.
Slave The input bit rate must equal the useful bit rate.
Slave mode TS lock
In slave MFN mode, this selects the TS input to which the modulator locks its
internal clock. Options are:
HP The modulator is synchronised with the HP TS.
LP The modulator is synchronised with the LP TS (hierarchical modes only).
Cell ID
This number from 0 to 65535 serves to identify the cell from which the DVB-T/H
signal comes from. Its main application is in DVB-H though its use is optional in DVB-T.
