Making Measurements using Frequency Dependent Offset Tables
This section describes how to use frequency dependent offset tables.
Frequency dependent offset tables provide 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.Select the table to work on a channel. Refer to “Selecting a Frequency Dependent Offset Table”, on page
2.Zero and calibrate the power meter. The reference calibration factor used during the calibration is automatically set by the power meter from the sensor calibration table (if selected).
3.Specify the frequency of the signal you want to measure. The calibration factor/offset is automatically set by the power meter from the sensor calibration table (if selected) and the frequency dependent offset table. Refer to “Making the Measurement”, on page
4.Make the measurement.
Selecting a Frequency Dependent Offset Table
You can select a frequency dependent offset table for use by pressing
