AFANalyzer subsystem
:NOTCh:GAIN <string>
:NOTCh:GAIN?
These commands set/query the gain of the AF analyzer’s notch filter 
amplifier. 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:NOTC:GAIN 
command, the value you send will be overridden by the autoranging 
function.
