For 70/140 MHz – the valid range is 52-88 or 104-176 MHz (in 100 Hz steps).
For L-Band – the 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.
Select Spectrum to counteract frequency converters that invert the spectrum. Use the  arrow
keys to select Normal or Invert. Press [ENT].
(CONFIG:) Tx  Power
Tx Power: State:On
Control:
Use the arrow keys to select State, Level, or Control. Press [ENT].

• RTS (Request to Send) is an interface signaling control. If enabled, RTS can be used to
control the output state of the modulator. Only available when using either the EIA-530 or
HSSI interface.
• 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.
