Spectrum
Normal
or
Invert
, (used to counteract frequency converters that invert the
spectrum)
IMPORTANT
When entering an IF frequency, the M&C will check the occupied
bandwidth calculated from the data rate, modulation type, code rate
and overhead, and will not allow an IF frequency to be entered if the
occupied bandwidth falls outside of the minimum or maximum IF
frequencies.
