Making Measurements with the Agilent 8480 Series Power Sensors

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.
1. Ensure that no power is applied to the power sensor.

wait symbol is displayed.
4. Connect the power sensor to the POWER REF output.
5. The current setting of the reference calibration factor is displayed under the
softkey. To change this setting press
