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 when the default unit is
linear, and when the default is logarithmic.
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
Figure 1-6 on page 99).
Example
The following example program, in HP Basic, details how to use the channel and
display offsets on an N8262A making a Channel A/B ratio measurement.
The final result is:
You can only use LOSS2 and GAIN2 for external losses and gains. LOSS1 and GAIN1
are specifically for calibration factors.
