Setting Frequency Dependent Offsets
Frequency dependent offset tables provide a quick and convenient method of
compensating for frequency related changes in the response of your test system.
Note that when selected, frequency dependent offset corrections are applied IN
ADDITION to any correction for sensor frequency response.
The power meter is capable of storing 10 frequency dependent offset tables with a
maximum of 80 frequency points each.
To use frequency dependent offset tables:
1 Select the table to be applied to a channel. Refer to “Setting Frequency
Dependent Offsets” on page 65 for further information. If you require to edit
the table refer to “Editing Frequency Dependent Offset Tables” on page 68 for
further information.
2 If an 8480 Series, N8480 Series, an E-Series, or an U2000 Series sensor is
used, zero and calibrate the power sensor. 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 “Procedure” on page 66 for further information.
4 Make the measurement.
Selecting a Frequency Dependent Offset Table
You can select a frequency dependent offset table from the key menu
followed by , , and for Channel A or Channel B.
For Channel C, you can select the frequency dependent offset table from the
key menu followed by , , and .
For Channel D, you can select the frequency dependent offset table from the
key menu followed by , , and .
