Procedure and the AC Flatness Adjustment Procedure in this chapter.

A DC adjustment is performed on the AFG by reading a series of voltages
output by the AFG, then entering those values back into the AFG. After all
measurements have been completed, new calibration constants are
calculated and stored in non-volatile memory. To ensure accuracy, perform
the DC calibration procedure at one-year intervals.
This procedure uses a firmware routine to adjust the AFG's DC calibration
constants. The

routine.
If an error occurs at any time during the procedure, abort (

command to find out which firmware revision you are using.
