SCOPE OF
THIS
MANUAL
This
manual
provides descriptive material
and
instructions for the
installation,
operation,
maintenance,
and
repair
of
this
instrument.
Wavetek's product improvement program
ensures that
the
latest
electronic
developments
are
incorporated
in
all
Wavetek
instruments by the addition
of
circuit
and component
changes as rapidly as
development and
testing permit.
Due
to the time
required to
document
and
print instruction manuals,
it
is
not always
possible to incorporate
the
more
recent changes
in
the
released
manual.
In this case,
data
will
be
found on
engineering
change
sheets at the
rear
of the manual.
If
no change
sheets are included, the
manual
is
correct
as printed.
