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 8½-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.
