PARTS ORDERING INFORMATION
Replacement parts are available from or through your local
Tektronix, Inc. Field Office or representative.
Only the circuit number will appear on the diagrams and
circuit board illustrations. Each diagram and circuit board
illustration is clearly marked with the assembly number.
Assembly numbers are also marked on the mechanical exploded
views located i n the Mechanical Parts List. The component
number is obtained by adding the assembly number prefix t o the
circuit number.
Changes t o Tektronix instruments are sometimes made to
accommodate improved components as they become available,
and to give you the benefit of the latest circuit improvements
developed in our engineering department. It is therefore impor-
tant, when ordering parts, t o include the following information in
your order: Part number, instrument type or number, serial
number, and modification number if applicable.
The Electrical Parts List is divided and arranged by
assemblies i n numerical sequence (e.g., assembly A1 with its
subassemblies and parts, precedes assembly A2 with its sub-
assemblies and parts).
If a part you have ordered has been replaced with a new or
improved part, your local Tektronix, I nc. Field Office or represen-
tative will contact you concerning any change in part number.
Chassis-mounted parts have no assembly number prefix
and are located at the end of the Electrical Parts List.
Change information, if any, is located at the rear of this
manual.

Electrical Parts List)
LIST OF ASSEMBLIES
A list of assemblies can be found at the beginning of the
Electrical Parts List. The assemblies are listed i n numerical order.
When thecompletecomponent number of a part is known, this list
will identify the assembly i n which the part is located.
lndicates part number t o be used when ordering replace-
ment part from Tektronix.
CROSS INDEX-MFR. CODE NUMBER TO
MANUFACTURER
SERIAL/MODEL NO. (columns three and four
of the Electrical Parts List)
The Mfr. Code Number to Manufacturer index for the
Electrical Parts List is located immediately after this page. The
Cross Index provides codes, names and addresses of manufac-
turers of components listed i n the Electrical Parts List.
Column three (3) indicates the serial number at which the
part was first used. Column four (4) indicatestheserial number at
which the part was removed. No serial number entered indicates
part is good for all serial numbers.
ABBREVIATIONS
Abbreviations conform to American National Standard Y1 .l. NAME 8a DESCRIPTION (column five ~f the
Electrical Parts List)
I n the Parts List, an ltem Name is separated from the
description by a colon (:). Because of space limitations, an ltem
Name may sometimes appear as incomplete. For further ltem
Name identification, the U.S. Federal Cataloging Handbook H6-1
can be utilized where possible.
COMPONENT NUMBER (column one of the
Electrical Parts List)
A numbering method has been used t o identify assemblies,
subassemblies and parts. Examples of this numbering method
and typical expansions are illustrated by the following:
Example a. component number
-
A23R 1 234 A23 R1234
