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 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.
Application
[a]
[a] In addition to the internal DMM, these applications require an input multiplexer module. The Keysight DAQM901A
multiplexer module is recommended.
