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.
If the Option 521 Detector Calibration is inadvertently used, the PSG has the
NOTE
ability to recall the factory amplitude flatness calibration. Refer to
the Factory Flatness
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 >

Restoring the Factory Flatness Calibration
