Adjustments
30 34450A Service Guide
Valid gain and frequency compensation input values.
Gain adjustment can be accomplished using the preset calibration points.
DC voltage gain adjustment procedure
Review the “Test Considerations” on page 5 and “Gain adjustment
considerations” on page 29 sections before beginning this procedure.
CAUTION
Never turn off the instrument during a gain adjustment. This may cause calibration
memory for the present function to be lost.
