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
unit is linear, and
You can only use LOSS2 and GAIN2 for external losses and gains. LOSS1 and
NOTE
GAIN1 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. On the Keysight
EPM-442A this offset is applied after any math calculations (refer to
