RF Output Command
Response
Status
Response >add/RF_xxx’cr’’lf’]
>add/RF_xxx’cr’’lf’] Where xxx = ON, WRM, OFF, default = OFF
The OFF command will keep the RF output turned off under all
conditions. The WRM command is a conditional ON command
telling the RF output to come on after the unit is warmed up and
meets the stability requirements. The ON command is an override
instructing the output to be on and ignores the warm start.

Response
Status
Response >add/UCA_nn.n’cr’’lf’]
>add/UCA_nn.n’cr’’lf’] Where nn.n = 0.0 to 25.0 (in dB, variable in 1.0 dB steps)
Note: No decimal point is displayed when UAGC is OFF and the
UCA range is extended to 55 dB.

Where: n = 1, 2, or 3
nnnnn.n = 13750.0 to 14500.0 MHz (UC frequency)
nnnnn.n = 10950.0 to 12750.0 MHz (DC frequency)
nn.n = 0.0 to 25.0 dB (UC attenuation)
nn.n = 0.0 to 20.0 dB (DC attenuation)
or "None" if a configuration does not exist in that
particular preset location.
Allows the user to select any one of three “PreSet” configurations.
The users must first program (STORE) a configuration using the
PGM_n command. This command used without the “PreSet”
number (n) will provide the current programming of each of the
three “PreSet” configurations.
The PGM_ and SEL_ pair of remote commands are similar to a
"Save" and "Recall" pair of commands. UC and DC frequency and
attenuation data are "saved" at the user's discretion and "recalled" for
use at a later time.
