Gain Calibration Adjustment Overview
The ADC and zero calibration adjustment procedure must have been recently performed before beginning
gain calibration. Gain calibrations can be made using either the front or rear input (not available on the
34460A) terminals. On the 34461A/65A/70A, make sure the
Front/Rear
switch matches the terminals in
use.
Never turn off the instrument during a gain or flatness calibration. This may cause calibration memory for
the present function to be lost.
Valid Gain and Flatness Calibration Input Values
Gain calibration can be accomplished using the following input values.
