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.
