MANUAL CHANGE INFORMATION
At Tektronix, we continually strive to keep up with latest
electronic developments by adding circuit and component
improvements to our instruments as soon as they are devel-
oped 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
following pages.
A single change may affect several sections. Sections of
the manual are often printed at different times, so some of
the information on the change pages may already be in
your manual. 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
in this section, your manual is correct as printed.
