Chapter 3Adjustments
Introduction The procedures in this chapter show how to perform the follow ing
electronic adjustments for the AFG:
•DC Accuracy
•AC Flatness (250 kHz and 10MHz filters)
•Skew
NOTE The DC adjustment procedure should be performed before the AC flatness
adjustment procedures.

Required

Equipment See Table 1-1 for test equipment required for the pr oc e dur e s desc ri be d in
this chapter.

Recommended

Environment Before performing these procedures, allow the AFG t o warm up for at least
one hour. The temperature should be within ±5oC of Tcal (the temperature
of the most recent calibrati on), and between 18oC and 28oC.

Calibration Commands

This section provides a brief description of command s tha t r elat e to
calibration of the AFG. More informat ion on these commands can be found
in the Command Reference section of the Agilent E1445A User’s Manual.
•CALibration:COUNt? returns the number of times that the AFG
has been calibrated. Each adju stment procedure in this chapter
increments the calibration number by 1.
•CALibration:SECure:CODE <code> sets the code that disables
calibration security. The code is set at the factor y to "E1445A".
Calibration security must be disabled before changing the code.
