Replacement parts are available from or through your local Tektronix
Field Office.
Changes to Tektronix instruments are sometimes made to accommo
date improved components as they become available, and to give you
the benefit of the latest circuit improvements developed in our engineer
ing 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 im
proved part, your local Field Office will contact you concerning any
change in part number.
