Service and Utility Menus
Utility Service Menu
Ref Oscillator Tune
This adjustment is intended for use by the user to make any fine tuning they
would like to the frequency output of the instrument. This adjustment is not the
same as the Reference Internal Standard Calibration provided with the
Performance Verification and Adjustment software for servicing the instrument.
The value entered for this setting is used in addition to the factory tune setting.
Setting this value to 0 will make the instrument use only the factory setting.
Execute ALC Modulator Bias Adjustment
This runs the Open Loop Power Calibration, which is the same as one of the
adjustments in the Performance Verification and Adjustment software provided
for servicing the instrument. Since there is no equipment required for this
adjustment the user can execute it to compensate for open loop power drift
due to temperature and humidity.
Save/Recall UI Flexible Naming
This is for user preference of the save and recall system for user state files.
