Setting Channel Offsets

The power meter can be configured to compensate for a signal loss or gain in your test
setup (for example, to compensate for the loss of a 10 dB attenuator). This gain or
loss, referred to as a channel offset, is added to the measured power before the result
is displayed.
Offsets are entered in dB. The allowable range of values is -100 dB to +100 dB. A
positive value compensates for a loss, and a negative value compensates for a gain.
If either a channel or a display offset is set then "Ofs" is displayed.
