The procedures in this chapter show how to electronically adjust the AFG
for DC accuracy and AC flatness.
The DC adjustment should be performed before the AC flatness adjustment.
A digital multimeter (DMM), a power meter, and a power sensor are
required for the procedures in this chapter. The HP 3458A is the
recommended DMM. The HP 8902A Measuring Receiver with an
HP 11722A sensor module is recommended for the AC flatness adjustment.
Before performing these procedures, allow the AFG to warm up for at least
one hour. The temperature should be within
most recent calibration and between 18
This section provides a brief description of commands that relate to
calibration of the AFG. More information on these commands can be found
in the Command Reference section of the HP E1340A User's Manual.

the appropriate calibration constant(s) can be calculated. The AFG
returns two numbers: (1) the current calibration point, and (2) an
error code. Any non-zero error code indicates a failure. This
command also sets up the AFG for the next calibration point.
