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.
If you are using an 8480 Series sensors or N8480 Series sensor with
Option CFT, the reference calibration factor used during the calibration
must 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.
Figure 1- 1 illustrates how frequency dependent offset tables operate.
