Selftest & Calibration Series 2040 Maintenance Manual V2.00 SELFTEST AND CALIBRATION OVERVIEW Calibration on the Series 2040 Functional Test System is completely automated. All calibration is based on high precision references built into the system Testhead and the Selftest Assembly. A high precision Temperature Compensated Crystal Oscillator (TCXO) on the Time Measurement System Board (TMS) is used as a frequency/time reference. A precision digital to analog converter (TDAC) contained within th

Series 2040 Maintenance Manual V2.00 Selftest & Calibration SELFTEST Selftest on the Series 2040 Test System is an automated procedure. The programs that comprise Selftest are organized under the Selftest Executive in a test menu called “Functional”. These programs exercise the hardware functions available to the user through the hardware functional calls. To perform Selftest, proceed as follows: 1) Install the Selftest unit on the Patchboard assembly as shown below: A) Pull the locking handle t

This box contains three separate ways of reporting the data collected during the tests. Data may be stored to a file, displayed on the screen and/or printed. In addition, each of these three reporting functions can report “All Data”, “Fail Data” or “No Data”. “All Data” includes all of the pass or fail sequences from the test. “Fail Data” includes only information on the tests

Select “Functional” from the Selftest Executive screen, and the Functional menu will appear as shown below. The Functional test menu has been organized so that tests closely related are blocked together in groups. If only one test is to be run, use the mouse to select that particular test. If a related group of tests is to be run, the

Selftest & Calibration Series 2040 Maintenance Manual V2.00 CALIBRATION Whenever a Testhead board is replaced, or any time that Selftest determines a failure, a calibration must be performed. If a unit passes the complete Functional Selftest routine, a calibration is not necessary. When Calibrate is selected from the Selftest Executive, the screen shown to the right is displayed. The Calibrate menu operates under the same basic rules as the Functional menu. For installation purposes, use the mou
