Digitizers Verification Tests

Introduction

Types of Tests

This appendix provides information on functional and performance verification of the E1563A 2-Channel Digitizer and E1564A 4-Channel Digitizer.

You can perform performance verification tests at two different levels depending on need:

Functional Verification Test - A series of internal verification tests (self-tests) that give a high confidence that the digitzer is operational. The self-tests take less than 20 seconds to complete.

Performance Verification Test - A complete set of tests that are recommended as an acceptance test when the instrument is first received or after performing calibration of the digitizer.

WARNING Do not perform any of the following verification tests unless you are a qualified, service-trained technician and have read the WARNINGS and CAUTIONS in Chapter 1 and the Warnings and Safety information in the front matter.

Recommended Test Equipment

Test equipment recommended for the performance verification and calibration procedures are listed in Table D-1. Use a source with accuracy requirements indicated in the table for any substitute calibration standard. You should complete the Performance Verification tests at one year intervals. For heavy use or severe operating environments, perform the tests more often.

Special care must be taken to ensure that the calibration standards and test procedures used do not introduce additional errors. Ideally, the standards used to test and calibrate the digitizer should be an order of magnitude more accurate than each digitizer range full scale error specification.
