IF Gain Offset
Sets the IF Gain offset for the 40 MHz, 140 MHz IF Paths in 2 dB step from –6 dB to +6 dB. Increasing
the gain can increase the amplitude of small signals as long as you don't overdrive the hardware.
Wideband gain should usually be adjusted after setting the input attenuation.
The IF Gain key is enabled for all IF Path selection but the IF Gain Offset is not activated when IF Path
Selection is Narrow and IF Path Selection Narrow is either 10 MHz or 25 MHz.
Internally, the IF Gain value will change based on the current configuration of the HW. If the user
chooses to offset this value, they may do so with this parameter. Hence the value specified is not an
absolute value but relative to the current internal IF Gain setting.
For example:

This only applies to the RF input. It does not apply to baseband I/Q input.
You must be in the IQ Analyzer (Basic) mode to use this command. Use
INSTrument:SELect to set the mode.
