performance
Once
a
measurement calibration
has been
generated with
a user-dened
calibration kit,
its
performance should
be checked
before making
device measurements
.
T
o
check
the
accuracy
that
can
be obtained
using the
new calibration
kit,
a
device
with
a
well-dened
frequency
response
(preferably
unlike any
of the
standards used)
should
be
measured.
The
verication
device
must
not be
one of
the calibration
standards:
measurement
of
one
of
these
standards
is
merely
a
measure of
repeatability.
To
achieve more
complete verication
of
a
particular
measurement
calibration,
accurately
known verication
standards with
a diverse
magnitude
and
phase
response
should
be
used. National
standard traceable
or HP
standards
are
recommended
to
achieve
veriable
measurement accuracy
.
Note
The
published
specications
for
the
HP

network
analyzer
system
include
accuracy
enhancement
with
compatible
calibration
kits
.
Measurement
calibrations
made
with
user-dened
or
modied
calibration
kits
are
not
subject
to
the
HP
8753D
specications
,
although
a
procedure
similar to
the system
verication
procedure
may
be
used.
