DTG5078 & DTG5274 Data Timing Generator Service Manual xv
Preface
This manual provides information necessary for service technicians to service the
DTG5000 Series Data Timing Generator 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 contains a brief description
of each manual section.
HSpecifications contains a description of the data timing generator 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 the data
timing generator functions properly and meets warranted limits.
HAdjustment Procedures contains information that you need to manually
adjust the data timing generator so that it meets specifications.
HMaintenance contains information and procedures for performing preventive
and corrective maintenance of the data timing generator. These instructions
include cleaning, module removal and installation, and fault isolation to the
module.
HReplaceable Electrical Parts contains a statement referring you to Replace-
able Mechanical Parts, where both electrical and mechanical modules are
listed.
HDiagrams contains block diagrams and an interconnection diagram.
HReplaceable Mechanical Parts includes a table of all replaceable modules,
their descriptions, and their Tektronix part numbers.

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 conven-
tions:
HName of front panel controls and menus appears in the same case (initial
capitals, all uppercase, and so on) in the manual as is used on the data timing
generator front--panel and menus. Front --panel names are all upper case
letters (for example, MENU, SELECT, PULSE GEN, and so on).
HInstruction steps are numbered unless there is only one step.
Throughout this manual, any replaceable component, assembly, or part of the
data timing generator 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 data timing generator is a module.
Symbols and terms related to safety appear in the Safety Summary near the
beginning of this manual.
Finding Other Information
This manual mainly focuses on the performance verification, troubleshooting and
maintenance of the data timing generator. See the following list for other
documents supporting the data timing generator operation.
