PARTS ORDERING IN F O R M A T IO N
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 developed in our engineering department. It is therefore important, when
ordering parts, to include the following information in your order: Part number, instru­
ment type or number, serial or model number, and 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.
