MTX100 MPEG Recorder & Player Service Manual xiii
Preface
This is the service manual for the MTX100 MPEG Recorder & Player. This
manual contains information needed to service an MTX100 to the module level.
Manual Structure
This manual is divided into sections, such as Specifications and Theory of
Operation. Further, some sections are divided into subsections, such as Product
Description and Removal and Installation Procedures.
Sections containing procedures also contain introductions to those procedures.
Be sure to read these introductions because they provide information needed to
do the service correctly and efficiently. The following are brief descriptions of
each manual section.
HSpecifications contains a description of the MTX100 and the characteristics
that apply to it.
HOperating Information includes general information and operating
instructions.
HTheory of Operation contains circuit descriptions that support service to the
module level.
HPerformance Verification contains procedures for confirming that an
MTX100 functions properly and meets warranted characteristics.
HAdjustment Procedures contains a statement explaining that no adjustment is
needed for the MTX100.
HMaintenance contains information and procedures for performing preventive
and corrective maintenance on an MTX100. These instructions include
cleaning, module removal and installation, and fault isolation to the module
level.
HOptions contains descriptions of available options for the MTX100.
HElectrical Parts List contains a statement referring you to the Mechanical
Parts List section, where both the electrical and mechanical modules are
listed.
HDiagrams contains block diagrams and interconnection diagrams of the
MTX100 and the optional interface modules.
HMechanical Parts List includes a table of all replaceable modules, their
descriptions, and their Tektronix part numbers.

Preface
xiv MTX100 MPEG Recorder & Player Service Manual
Manual Conventions
This manual uses certain conventions that you should become familiar with.
Some sections of the manual contain procedures for you to perform. To keep
those instructions clear and consistent, this manual uses the following
conventions:
HNames of front panel controls and menus appear in the same case (initial
capitals, all uppercase, etc.) in the manual as is used on the MTX100 front
panel and menus.
HInstruction steps are numbered unless there is only one step.
HBold text refers to specific interface elements that you are instructed to
select, click, or clear.
Example: To power on the MTX100, press the ON/STBY switch.
HItalic text refers to document names or sections. Italics are also used in
NOTES, CAUTIONS, and WARNINGS.
Example: The Diagrams section, beginning on page 9-1, includes a block
diagram and an interconnect diagram.
Throughout this manual, any replaceable component, assembly, or part of the
MTX100 is referred to generically as a module. In general, a module is an
assembly (like a circuit board), rather than a component (like a resistor or an
integrated circuit). Sometimes a single component is a module. For example, the
chassis of the MTX100 is a module.
Symbols and terms related to safety appear in the Safety Summary near the
beginning of this manual.
Finding Other Information
Other documentation for the MTX100 includes:
HThe MTX100 MPEG Recorder & Player User Manual contains a tutorial to
quickly describe how to operate the MTX100. It also includes an in-depth
discussion on how to more completely use the MTX100 features.
