Dening
a Custom
Fixture Compensation
Kit
This
section explains
how to
dene
a
custom
xture
compensation
kit.
The
4395A incorporates
a database
of
Agilent's
genuine
test
xtures
and
their
specic
compensation
coecients.
Therefore,
as
long
as
you
use
an
Agilent's
genuine
test
xture
,
you
can
use the
xture without
dening
an
associated
compensation
kit.
If
you
use
your
custom
test
xture
to
meet
your
actual
needs
,
however
,
you
must
dene
the
compensation
kit
associated
with
the
xture
before
you
can
use
your
custom
test
xture
.
Once
you
have
dened
a
xture
compensation
kit,
the
4395A
preserves
the
denitions
so
you
can
select
the
compensation
kit
whenever
you
need
to
use
it.
The
4395A
uses
the
following
equivalent
circuit
to
perform
xture
compensation
for
each
of
the
OPEN,
SHORT
,
and
LO
AD
circuit
