Verification
Introduction
This chapter contains test procedures that check the operation and calibration of the Agilent 60501B/60502B Electronic Load Modules. The tests are performed from the front panel of an Agilent 6050A/6051A Electronic Load Mainframe with the module installed in slot 1. The tests can also be used to determine which circuits are faulty when troubleshooting. There are some transient, trigger, and pulse functions that require an GPIB controller and will not be verified with manual testing from the front panel. The following tests will verify, with a high level of confidence, that the module is operating properly without testing all of its capabilities.
At the end of this chapter are performance record tables where actual measured values can be recorded.
