Setting Offsets
The power meter can be configured to compensate for a signal loss or gain
in your test setup. The power meter allows you to apply offsets at three
different points in the measurement path.
Figure 2-24
Simplified measurement path
Figure 2- 24
shows that how you can apply a
Channel Offset
or a
Frequency Dependent Offset
prior to any mathematical functions. These
allow you to compensate each channel individually. An overall offset can
be applied if required using the
Display Offset
.
Setting Channel Offsets
This gain or loss is applied to the measured power before any
mathematical functions, display offsets or relative functions are included.
Offsets are entered in dB and the range is –100 dB to +100 dB.
A positive value compensates for a loss and a negative value compensates
for a gain.
