Performance Tests and Calibration
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 with another calibration standard of equivalent accuracy.
A suggested alternative method would be to use the Keysight 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.
