Making Measurements with the HP 8480 Series Power Sensors
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 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 ZerCalo .
3.Press Zero A. During zeroing, which takes approximately 10 seconds, the wait symbol is displayed.
4.Press Cal.
5.Connect the power sensor to the POWER REF output.
