Overload Detector DAC Adjustment

The overload detector is in the first IF in the A20 Low Band. It is used as a warning when a high input level outside the viewing span is compressing the first mixer. It can also be used as a diagnostic tool.

This adjustment should be performed after replacing the A20 assembly.

This adjustment saves an output file which lists the corrections that were stored in the instrument. The output file is saved at this location:
