Introduction

Before You Begin

This short introduction emphasizes a few safety precautions that you need to
keep in mind when servicing the MTS200 Series MPEG Test System, describes
a service strategy for repairing the test system, and lists Tektronix service options
available for this product.

To prevent injury to yourself or damage to the test system, fulfill the following
requirements before you service your test system:

H Be sure you are a qualified service person.
H Read the Safety Summary found at the beginning of this manual.
H Read Service Strategy, below.

Be sure to heed all warnings, cautions, and notes in this manual when servicing
your test system.

Service Strategy

This manual contains the following service procedures:

H Performance verification procedures
H Adjustment procedures for the Data Store and synchronous serial interface

boards

H Periodic maintenance
H Module removal and replacement
H Module-level fault diagnosis

Use the module-level fault diagnosis section (in the Maintenance section) to
isolate problems to a specific module. Once you isolate a problem with a
module, use the Replaceable Parts List in this manual to determine the correct
module part number to order from Tektronix. Use the remove and replacement
procedures to remove and replace defective modules. Use the performance
verification and adjustment procedures to verify the accuracy of your test system
after installing a new module (or for periodic maintenance).

requirement column; it may include typical performance characteristics for the
instrument. Statements in this column are not considered to be guaranteed
performance and are not ordinarily supported by a Performance Verification
procedure.

Performance Conditions

The specifications are valid for test systems under the following conditions:

H The test system is operating within the environmental limits listed in

H The test system has been adjusted at 25_ C ±5_ C.
