Frequency Specific Calibration Factors

This section shows you how to make a measurement using the calibration
factor for the frequency of the signal you want to measure.
Tip
Procedure
First, select and enter the reference calibration factor for the desired
sensor as follows:
1 Ensure the power sensor is disconnected from any signal source.
2 Refer to the connection requirements in
3 Check the current reference calibration factor setting by pressing
Does this setting match the value for the sensor? (The power sensor reference calibration
N O T E
factor can normally be found above the calibration factors table on the power sensor body.)
4 To change the settings, press the channel
132
This method is best suited to making several measurements at one
frequency as you need only enter a small amount of data.
Using this method requires the following steps:
1 Zero and calibrate the power meter/sensor combination.
2 Set the calibration factor value for the frequency of the signal you
want to measure.
3 Make the measurement.
