Making Measurements using Sensor Calibration 
Tables
This section applies to all Agilent 8480 series power sensors. It does not 
apply to the Agilent E-series power sensors. 
For the Agilent 8480 series power sensors there are two methods of 
providing correction data to the power meter:
A inputting the individual calibration factor for a frequency prior to 
making the measurement, or
B using 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 2-21 for further information. If you 
require to edit the table refer to “Editing Sensor Calibration 
Tables”, on page 2-23 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. 
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 2-22 for further information.
4. Make the measurement.
