FM Scale DAC Offset Calibration
Description
This calibration is used to remove the offset associated with the FM SCALE DAC operational amplifier
located on the A17 Synthesizer (Option 501, 502, 503, 504). 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.
Required Test Equipment
• Agilent 53132A Option 050 frequency counter
