MOD CF
50.000,000 Hz
to 175,000,000
70000000
Hz
Used to set the modulator carrier frequency. The
acceptable range of options is implemented with a
pass band filter that filters out all frequencies below
and above the range. When selecting a carrier
frequency, you must take into account the satellite
bandwidth required for transmission. If you select a
carrier frequency that is too close to either end of
the valid range, data may be clipped by the pass
band filter. For information on calculating the
satellite bandwidth, see the MOD SR command.
MOD POW

SYMBOL_
RATE
Sets the “master rate setting mechanism for the
modulator
SYMBOL_RATE = symbol rate is settable – data
rate is calculated and read only
DATA_RATE = Data rate is settable – symbol rate
is calculated and read only
AUTO = Both data rate and symbol rate are
settable and the other is calculated
