5.1
DIAGRAMS
The
schematic diagrams within this
manual
are,
wherever
possible,
arranged
in
the sequence followed
in
the circuit
description.
Whenever assembly drawings
are included,
they
are positioned adjacent to the schematics for
maximum
information presentation and
minimum
page flipping.
Additional voltage or
waveform
information,
beyond
that
given
in
the
circuit
description,
may
be
shown on
the
schematic
diagrams, at test
points and key locations
throughout
the instrument.
5.2
ADDENDUMS
Under
WAVETEK's
product
improvement
program, the
latest
electronic designs and
circuits
are incorporated into
each
WAVETEK
instrument
as
quickly
as
development and
testing
permit. Because of the time needed to compose and
print instruction manuals,
it is
not always
possible to in-
clude the
most
recent changes
in
the
initial
printing.
When-
ever
this
occurs,
addendum
pages are prepared to summarize
the
changes made under
a
WAVETEK
Engineering Change
Notice
(ECN) and
these
ECN
pages are inserted
immediately
inside the rear cover.
If
no such pages exist, the
manual
should be correct
as prfhted.
