Installing the Calibration Factors
Cal factors can be entered and stored in an internal table (Automatic Cal Factors)
in the PSA's non-volatile memory. The table is automatically accessed during RF
power measurements (after the measuring receiver has tuned to the frequency) to
correct for the non-linear response of the power sensor. If no entry in the table
directly corresponds to the frequency being measured, the measuring receiver
derives a cal factor through linear interpolation using the nearest calibration points
in the table.
Installing the Cal Factors in the N5530S
There are two methods of installing the sensor module calibration factors (cal
factors) in the N5530S Measuring Receiver System.
The first method loads and saves the cal factors using the PC. The second method
uses the PSA to load the data.

Both methods are accessed through the Utilities drop-down menu (See

Using the PC to Load and Save the Cal Factors
1. Insert the N5532A Sensor Module Data Disk in the PC A:\ drive.
If your PC does not have a floppy disc drive, use the PSA to save your cal data to
NOTE
your PC. Then use this procedure to load the sensor cal factors into the system.
2. Select Calibration Factors to bring up the Calibration View Edit dialog box.
3. Press Load Cal File in the Calibration View Edit dialog box. The Open
Calibration File dialog box appears.
4. Navigate to the PC A:\ drive if necessary and select the CFData.XML file.
NOTE
If you obtained the cal data from the PSA, go to the directory you specified in
2
of the next section to load the data.
