REPLACEABLE ELECTRICAL PARTS
This section contains a list of the components that are
replaceable for the TSG 200. Use this list to identify and
order replacement parts. There is a separate Replaceable
Electrical Parts list for each instrument.
Parts Ordering Information
Replacement parts are available from or through your local
Tektronix, Inc., Field Office or representative.
Changes to Tektronix instruments are sometimes made to
accommodate improved components as they become
available and to give you the benefit of the latest circuit
improvements. Therefore, when ordering parts, it is
important to include the following information in your order.
Part number
Instrument type or model number
Instrument serial number
Instrument modification number, if applicable
If a part you have ordered has been replaced with a new or
improved part, your local Tektronix, Inc., Field Office or
representative will contact you concerning any change in
part number.
Change information, if any, is located at the rear of this
manual.
Using the Replaceable Electrical
Parts List
The tabular information in the Replaceable Electrical Parts
list is arranged for quick retrieval. Understanding the
structure and features of the list will help you find all of the
information you need for ordering replaceable parts.
Cross Index–Mfr. Code Number to Manufacturer
The Mfg. Code Number to Manufacturer Cross Index for the
electrical parts list is located immediately after this page.
The cross index provides codes, names, and addresses of
manufacturers of components listed in the 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 in numerical
order. When the complete component number of a part is
known, this list will identify the assembly in which the part is
located.
Component No. (Column 1)
The component circuit number appears on the diagrams
and circuit board illustrations, located in the diagrams
section. Assembly numbers are also marked on each
diagram and circuit board illustration, in the Diagram section
and on the mechanical exploded views, in the mechanical
parts list. The component number is obtained by adding the
assembly number prefix to the circuit number.

The electrical parts list is arranged by assemblies in
numerical sequence (A1, with its subassemblies and parts,
precedes A2, with its subassemblies and parts).
Mechanical subparts to the circuit boards are listed in the
electrical parts list. These mechanical subparts are listed
