Preface
This manual contains service information for Tektronix MPEG Test Systems that
use the Compaq Prosignia 500 platform. Please read this introduction before
doing any repair or service work on the instrument.
This MPEG Test System is composed of a personal computer (hereafter called
the Server) that contains customized hardware and software. The software
applications are documented in the user manuals that arrived with your Server.
The information included in this manual explains how to verify, service,
troubleshoot, and repair the test system to the module level:
H Specifications describes functional characteristics and performance require-
ments for the MPEG Test System.
H Operating Information tells you how to install and operate the instrument.
H Theory of Operation provides descriptions of the test system modules.
H Performance Verification describes how to verify the functional performance
of the test system.
H Adjustment Procedures describes how to adjust the oscillator frequency.
H Maintenance contains the following information:
H How to safely handle static sensitive modules and components
H How to remove and replace modules
H Diagnostic and Troubleshooting information and procedures
H Options.
H Replaceable Parts List gives all module and mechanical parts that comprise
the test system. Parts are identified on an indexed illustration to make them
easier to identify.
H The appendices consist of the following items:
H Software Repair to help you replace damaged software.
H MTS100 Test System Application Software is the list of directories and
files that make up the applications.
