FM Scale DAC Offset Calibration
Description
This test is used to remove the offset associated with the FM SCALE DAC operational
amplifier located on the reference board. This calibration results in a DAC value for FM
OFFSET DAC 2. After this DAC value has been properly adjusted, the effects of the FM
SCALE DAC value on the offset will be minimized.
