Performance Tests and Calibration

Introduction

This appendix contains test procedures to verify that the dc source is operating normally and is within published specifications. There are three types of tests as follows:

Built-in Self Tests	These tests run automatically when the dc source is turned on. They
	check most of the digital circuits and the programming and readback
	DACs.
Turn on Checkout	These tests, described in chapter four, provide a high degree of
	confidence that your unit is operating properly.
Calibration Verification	These tests, documented in this appendix, verify that the dc source is
/Performance Tests	properly calibrated, and that the dc source meets all of the specifications
	listed in Appendix A

If the dc source fails any of the tests or if abnormal test results are obtained after performing a calibration, return the unit to an Agilent Technologies repair facility.

This appendix also includes calibration procedures for the Agilent N3280A. Instructions are given for performing the procedures from a controller over the GPIB.

IMPORTANT: Perform the Programming Accuracy and Readback Accuracy tests before calibrating your dc source. If the dc source passes the Programming Accuracy and Readback Accuracy tests, the unit is operating within its calibration limits and does not need to be re-calibrated.

Equipment Required

The equipment listed in the following table, or the equivalent to this equipment, is required for the calibration and performance tests. A test record sheet with specification limits (when test using the recommended test equipment) may be found at the back of this section.
