Optimizing Performance
Using the Option 521 Detector Calibration (Option 521)
Using the Option 521 Detector Calibration (Option 521)
CAUTION
Using the Option 521 Detector Calibration softkey changes the factory
calibration. Avoid using this feature unless following a service center’s
recommendations.
This calibration should be done whenever the instrument temperature
changes beyond specified parameters or and when greater amplitude
flatness is required around the 500 MHz frequency transition. Refer to the
Data Sheet
.
NOTE
If the Option 521 Detector Calibration is inadvertently used, the PSG has the
ability to recall the factory amplitude flatness calibration. Refer to
the Factory Flatness Calibration”
The purpose of this calibration is to improve the 500 MHz frequency transition
to compensate for changes in temperature. The 500 MHz frequency transition
can degrade as the temperature changes. By using the detector calibration,
when the instrument temperature change occurs, the PSG’s flatness
performance can be optimized. Refer to the
Data Sheet
.
Running the Option 521 Detector Calibration
Following the following steps to run the Detector calibration:
— Press
Amplitude > More > More > Option 521 Detector Calibration >
Execute
Restoring the Factory Flatness Calibration
The instrument’s original factory calibration settings can be restored by the
following steps:
— Press
Utility > Power On/Preset > Restore System Defaults
