Recommended Test Equipment
The test equipments recommended for the performance verification
procedures are 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.
