to save the current Sensor and Cal Factors information in the PSA and
will be loaded next time the PSA is powered on.
• To recall the power sensor calibration factors from the Flash memory of PSA.

to load the Cal Factors file saved in the PSA.
The format of the .XML File is shown in the following example:
<Calibration>
<ModelNumber>N5532A</ModelNumber>
<Options>518</Options>
<SerialNumber>US44330015</SerialNumber>
<DateCalibrated>20000101</DateCalibrated>
<ReferenceCF>98</ReferenceCF>
<CalFactor>
<Frequency Unit= “Mhz”>10</Frequency>
<CalFactor Unit= "Percent">99.2135310306974</CalFactor>
</CalFactor>
<CalFactor>
<Frequency Unit= “Mhz”>30</Frequency>
<CalFactor Unit= “Percent”>98.7875312060724</CalFactor>
</CalFactor>
</Calibration>
Most of the SCPI commands for the calibration factors file operations are
consistent with those in the MMEMory subsystem, for example, Catalog, Delete,
etc., except for Save and Load.
File Operations for Tuned RF Level Calibration Factors
TRFL measurements can support store and recall functions for the convenience of
repetitive TRFL measurements at many different frequencies. Because the cal
factors are dependent on the instrument setting and TRFL measurement setting, cal
factors are saved into a state file with instrument and measurement settings. When
you recall the cal factors, not only the cal factors are recalled, but all of the
instrument and measurement settings are recalled.
NOTE Cal factor values will become stale due to time and temperature drift, and
following the PSA align routines.
From the front panel
To start one set of cal factors at one frequency:
1. Press
