Using Frequency Dependent Offset Tables
This section describes how to use frequency dependent offset tables.
Frequency dependent offset tables give you the ability to compensate for
frequency effects in your test setup.

Overview

If the [SENSe[1]]|SENSe2:CORRection:CSET2:STATe command is
OFF, the frequency dependent offset tables are not used. When
[SENSe[1]]|SENSe2:CORRection:CSET2:STATe is ON, the frequency
dependent offset tables are used, providing you with a quick and
convenient method of compensating for your external test setup over a
range of frequencies. Note that when selected, frequency dependent offset
correction is IN ADDITION to any correction applied for sensor frequency
response. The power meter is capable of storing 10 frequency dependent
offset tables of 80 frequency points each.
To use frequency dependent offset tables you:
1. Edit a frequency dependent offset table if necessary.
2. Select the frequency dependent offset table.
3. Enable the frequency dependent offset table.
4. Zero and calibrate the power meter. The reference calibration
factor used during the calibration will be automatically set by the
power meter from a sensor calibration table, if enabled; otherwise
it should be entered manually.
5. Specify the frequency of the signal you want to measure. The
required offset is automatically set by the power meter from the
frequency dependent offset table.
6. Make the measurement.
