4 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 calibration 
standards of equivalent accuracy.
A suggested alternate method would be to use the Agilent 
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.
