Making Measurements using Frequency Dependent Offset
Tabl es
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 54 for further information. If you are
required to edit the table, refer to “Editing Frequency Dependent Offset
Tables” on page 56 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 or 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 45 for further information.
4 Make the measurement.
