Recommended Test Equipment
The test equipment recommended for the performance verification
and adjustment procedures is listed below. If the exact instrument is
not available, substitute calibration standards of equivalent accuracy.
A suggested alternate method would be to use the Agilent 3458A 8

digit Digital Multimeter to measure less accurate yet stable sources.
The output value measured from the source can be entered into the
instrument as the target calibration value.
