using the Display Offset.
Setting Channel Offsets
This gain or loss is applied to the measured power before any mathematical
functions, display offsets or relative functions are included.
Offsets are entered in dB and the range is –100 dB to +100 dB.
The equivalent range in % is from 0.0000000001% to 10000000000%.

gain.
