Recommended Test Equipment
The test equipment recommended for the performance
verification and adjustment procedures are listed below
(
Table 1- 1 ). If the exact instrument is not available,
substitute with another calibration standard of equivalent
accuracy.
A suggested alternative method is to use the Agilent 3458A
8½ Digit Digital Multimeter to measure less accurate but
stable sources. The output value measured from the source
can be entered into the instrument as the target calibration
value.
