Performance Test 4
Keysight U3401A User’s and Service Guide 73
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 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.
