For L-Band: Valid range is 950–2000 MHz (in 100 Hz steps).
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.

• When VSAT is selected, the output state of the modulator is controlled by the
demodulator carrier detect status. Modulator output will be enabled when the
demodulator is detected, and disabled otherwise.
This is reserved for future use.
