Making Measurements with the Agilent 8480 Series 
Power Sensors
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 make measurements without using sensor 
calibration tables, that is, inputting the individual calibration factor for a 
frequency prior to making the measurement. This method is 
advantageous if you are only measuring at one frequency, as entering all 
the calibration data in this instance is not required.
To make measurements without sensor calibration tables perform the 
following steps:
1. Zero and calibrate the power meter. Before carrying out the 
calibration you must set the reference calibration factor of the 
power sensor.
2. Set the calibration factor value for the frequency of the signal you 
want to measure.
3. Take a reading.
Procedure 
The following procedure details how to make a measurement on 
channel A. To make a measurement on channel B use the same procedure 
using the equivalent channel B softkeys. 
1. Ensure that no power is applied to the power sensor.
2. Press . 
3. Press  . During zeroing, which takes approximately 10 
seconds, the wait symbol is displayed.
4. Press . 
5. Connect the power sensor to the POWER REF output.
