TPG20 Service v
Preface
This manual provides a limited set of service information for the TEKTRONIX
TPG20 Test Pattern Generator and is intended for use by personnel who are
qualified to work inside the instrument. There is a separate manual that is
included with the instrument which provides operating instructions for the
generator.
The preface describes the contents of this service manual, and includes a brief
description of each section within the manual.
The Table of Contents is a detailed list of the sections, and the major divisions
within them. There are also lists showing the locations of illustrations and of
tables.
Section 1 contains the Performance Check and Calibration procedures, along
with a list of equipment required to complete them. The Performance Check
procedure is used to determine whether the instrument is performing within its
specifications, while the Calibration procedure shows how to perform the
adjustments necessary to restore the TPG20 to its specified operation.
Section 2 contains the Replaceable Parts List. Unlike most of our Replaceable
Parts Lists, the TPG20 Parts List combines electrical and mechanical parts in one
list. Nomenclature and ordering processes are different than normal for
Tektronix products, as well. Contact your TEKTRONIX representative
regarding replacement parts.
Section 3 contains the schematic diagrams, and an illustration of the Test Pattern
Generator board showing the location of all the components.
At the end of the manual there may be a tabbed page titled Manual Change
Information. Any pages following this tabbed page will contain the latest
changes and corrections to the instrument.
