4.14.4 IRD Demod Menu
Frequency Option
To access the Frequency option, press the Frequency softkey in the IRD
Demod Menu.
This value is either the L-Band frequency for the demodulator to tune to if
the LNB option is set to ‘Direct RF’, or it is the satellite frequency to tune
to if the LNB option is set to ‘Active’.
If the demodulator is M2/EOM2/QPSKDEMOD, and the IF input is selected,
then this value is the IF frequency to tune to.
Symbol Rate Option
To access the Symbol Rate option, press the Symbol Rate softkey in the
IRD Demod Menu. If the IRD is in tracking mode then this value is tied to
that set for the satellite modulator, and cannot be altered.
Table 4.134: Symbol Rate Options

Stepsize 0.0001 Msym/s
FEC Rate Option
To access the FEC Rate option, press the FEC Rate softkey in the IRD
Demod Menu. If the IRD is in tracking mode this value is tied to that set for
the satellite modulator, and cannot be altered.

1/2 IRD uses 1/2 FEC Rate
2/3 IRD uses 2/3 FEC Rate
3/4 IRD uses 3/4 FEC Rate
5/6 IRD uses 5/6 FEC Rate
7/8 IRD uses 7/8 FEC Rate
8/9 IRD uses 8/9 FEC Rate - only applicable if the modulation type is 8PSK
