20 Keysight U1281A/U1282A Service Guide
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 Keysight 3458A 8½-Digit Digital
Multimeter to measure less accurate but stable sources. The output value
measured from the source can be entered into the multimeter as the target
calibration value.
