Gain Calibration and

Test Conditions

This chapter provides information on performance verification of the HP

E1563A 2-Channel and HP E1564A 4-Channel Digitizers. 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.

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 preceding chapter 1 on page 4).

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.

Table D-1. Recommended Test Equipment.

Application

Verification

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.

All test procedures should comply with the following test conditions:

•

Ambient temperature of the test area is between 18°C and 28°C and

stable to within ±1°C.
