Using Frequency Dependent Offset Tables

This section describes how to use frequency dependent offset tables. These 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.
5 Specify the frequency of the signal you want to measure. The required offset is
6 Make the measurement.

CFT, the reference calibration factor used during the calibration must be
entered manually.
