Setting Offsets

Channel Offsets

The power meter can be configured to compensate for signal loss or gain in your
test setup (for example, to compensate for the loss of a 10 dB attenuator). You use
the SENSe command subsystem to configure the power meter. Gain and loss
correction are a coupled system. This means that a gain set by
[SENSe[1]]|SENSe2:CORRection:GAIN2 is represented in the
[SENSe[1]]|SENSe2:CORRection:LOSS2? command. If you enter an offset value
the state is automatically enabled. However it can be enabled and disabled using
either the [SENSe[1]]|SENSe2:CORRection:GAIN2:STATe or
[SENSe[1]]|SENSe2:CORRection:LOSS2:STATe commands.
LOSS2 is coupled to GAIN2 by the equation
linear, and
You can only use LOSS2 and GAIN2 for external losses and gains. LOSS1 and GAIN1
NOTE
are specifically for calibration factors.

Display Offsets

Display offset values can be entered using the CALCulate[1|2]:GAIN[:MAGNitude]
command. CALCulate[1|2]:GAIN:STATe must be set to ON to enable the offset
value. If you enter an offset value the state is automatically enabled. This offset is
applied after any math calculations (refer to
