Parts Ordering Information

Replacement parts are available through your local Tektronix, Inc., Field Office
or representative. The parts list for the TPG20 is different than the normal
TEKTRONIX parts lists. The nomenclature used is not the typical Tektronix
nomenclature, and the processes used to order replacement parts is different, as
well. Make sure to contact your local Tektronix representative when ordering
parts.
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.
