PARTS LIST A N D SCHEMATICS
Replacement parts are available from or through your local Tektronix Field Office.
Changes to Tektronix instruments are sometimes made to accommodate improved

improvements developed in our engineering department. It is therefore important, when
ordering parts, to include the following information in your order: Part number including
any suffix, instrument type, serial number, and modification number if applicable.
If a part you have ordered has been replaced with a new or improved part, your
local Tektronix Field Office will contact you concerning any change in part number.
