Appendix B 
Verification and Calibration 
Verification ......................................................................................................... 99 
Calibration ........................................................................................................ 128 
 
 
The verification procedures described in this appendix verify that the 
power supply is operating normally and is within published 
specifications. 
This appendix also includes calibration procedures for the Keysight 
N8700 power supplies. Instructions are given for performing the 
procedures from a controller over the GPIB. 
NOTE 
Perform the verification tests before calibrating your power supply. If the power 
supply passes the verification tests, the unit is operating within its calibration 
limits and does not need to be re-calibrated. 
The recommended calibration interval for Keysight N8700 power 
supplies is one year. 
 
Verification 
Verification procedures are of two types: 
Performance  These procedures verify that the power supply is operating normaly and 
meets all of the published specifications listed in Appendix A. These tests 
also verify the power supply is properly calibrated. 
Calibration  These procedures calibrate the power supply and set operation within the 
published specifications. Calibration is recommended annually. 
If the power supply fails any of the verification tests, perform the 
calibration procedures. If calibration is unsuccessful, return the unit 
to a Keysight Technologies repair facility (see Appendix D).
