Making Measurements using Sensor Calibration Tables
This section applies to all HP 8480 series power sensors. It does not apply to the HP
For the HP 8480 series power sensors there are two methods of providing correction data to the power meter:
Ainputting the individual calibration factor for a frequency prior to making the measurement, or
Busing sensor calibration tables.
This section describes how to use sensor calibration tables. Sensor calibration tables are used to store the measurement calibration factors, supplied with each power sensor, in the power meter. These calibration factors are used to correct measurement results.
Using sensor calibration tables provides you with a quick and convenient method for making power measurements over a range of frequencies using one or more power sensors. The power meter is capable of storing 20 sensor calibration tables of 80 frequency points each.
To use sensor calibration tables you:
1.Select the table to work on a channel. Refer to “Selecting a Sensor Calibration 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.
3.Specify the frequency of the signal you want to measure. The calibration factor is automatically set by the power meter from the sensor calibration table. Refer to “Making the Measurement”, on page
4.Make the measurement.
