AFANalyzer subsystem
:DEMPhasis:GAIN <string>
:DEMPhasis:GAIN?
These commands set/query the AF analyzer’s amplifier gain. This
command is only effective when autoranging is turned off using the
AFAN:RANG ‘Hold’ command.
Gain is automatically set when the AFAN:RANG ‘Auto’ command is
used. If autoranging is enabled (AFAN:RANG ‘Auto’) and you attempt
to change the gain setting by sending the AFAN:DEMP:GAIN
command, the value you send will be overridden by the autoranging
function.
