Selecting a Frequency Dependent Offset Table

Power Meter Operation

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 2-27 for further information. If you require to edit the table refer to “Editing Frequency Dependent Offset Tables”, on page 2-29 for further information.

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 2-28 for further information.

4.Make the measurement.
