C.5 Carrier RTS
Modulator output is turned off before reprogramming modulator functions that may alter the
output spectrum through the front panel, and the user is required to enter “Yes” to re-enable
output after the change. When using the terminal, the modulator is turned off while re-
programming modulator functions that may alter the output spectrum, and the user is required to
manually turn on the output after the reprogramming (same as “Carrier On”). Additionally “RTS”
(Request To Send) mode enables the modulator’s output based on the RTS lead of the data
interface. When RTS is enabled on the data interface, the modulator turns on the carrier, when
the RTS is disabled the modulator turns off the carrier.
