This
chapter
describes
the
calibration
of
the
mainframe
and
the
plug-in
modules
.
It
is
intended
to
give
you,
or
the
calibration
laboratory
personnel,
an
understanding
of
the
various
calibration
procedures
available
,
and
how
they
were
intended
to
be
used.
There
is
a
description
of
the
calibration
menu
included
in
the
manuals
provided
with
the
plug-in
modules
and
probes
.
Proper
calibration
is
critical
to
measurement
accuracy
and
repeatability
.
The
HP
54750A/83480A
and
their
associated
modules
and
accessories
require
that
both
factory
and
user
calibrations
be
implemented
at
the
recommended
intervals
in
order
to
perform
measurements
at
their
published
specications
.
This
chapter
is
divided
into
three
sections
.
The
rst
section
describes
factory
calibrations
.
A
factory
calibration
consists
of
verifying
instrument
performance
to
all
specications
.
If
an
instrument
fails
to
meet
specications
,
adjustment
or
repair
may
be
necessary
.
F
or
most
users
,
this
will
mean
shipping
the
instrument
back
to
an
authorized
service
center
.
Some
users
may
purchase
the
required
instrumentation
and
perform
the
factory
timebase
calibrations
themselves
using
the
optional
HP
83480A,
54750A
Service
Guide.
The
second
part
of
the
chapter
addresses
calibrations
that
are
routinely
performed
by
the
end
user
.
Subsections
in
each
of
the
two
main
sections
discuss
the
individual
calibrations
.
In
addition,
there
will
be
summary
tables
at
the
end
of
each
of
these
sections
summarizing
the
main
areas
addressed.
The
third
part
of
the
manual
consists
of
a
complete
calibration
summary
table
at
the
end
of
the
chapter
.
Both
factory
and
user
calibrations
must
be
3-2
