MANUAL CHANGE INFORMATION
At Tektronix, we continually strive to keep up with the latest
electronic developments by adding circuit and component im-
provements to our instruments as soon as they are developed and
tested.
Sometimes, due to printing and shipping requirements, we can't
get these changes immediately into printed manuals. Hence, your
manual may contain new change information on the following
pages.
A single change may effect several sections. Since the change
information sheets are carried in the manual until all changes are
permanently entered, some duplication may occur. If no such
change pages appear following this page, your manual is correct as
printed.
