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.
Procedure
First select and enter the reference calibration factor for the sensor you are using
as follows:
1 Ensure the power sensor is disconnected from any signal source.
2 Refer to the connection requirements in Table and ensure the sensor is ready
for connection to the Power Reference.
3 Check the current reference calibration factor setting by pressing ,
. The value is displayed under the channel softkey.
Does this setting match the value for the sensor? (The power sensor reference
calibration factor can normally be found above the calibration factors table on the
power sensor body.)
4 To change the settings, press the channel . The reference calibration
factor pop up window is displayed as shown in Figure 7-3. Use the numeric
keypad to enter the required value in the Ref Cal Factor pop-up menu.
TIP 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.
