OFFSET
DELAY
is
used to
specify the
one-way electrical
delay from
the
measurement
(reference) plane
to the
standard, in
seconds (s).
(In
a transmission
standard, oset
delay is
the
delay
from
plane
to
plane.)
Delay can
be calculated
from
the
precise
physical
length
of the
oset, the
permittivity constant
of
the
medium,
and
the speed
of light.

OFFSET
LOSS
is
used
to
specify
energy
loss
, due
to skin
eect, along
a
one-way
length
of
coax
oset.
The
value of
loss is
entered as
ohms/nanosecond
(or
Giga ohms/second)
at 1
GHz. (Such
losses
are
negligible
in waveguide
,so
enter 0
as the
loss
oset.)

Z0
is

(Note:
This is

itself.)
(F

the oset
impedance should
always be
assigned
a value
equal to

ONE-PATH

leads
to
the
series
of
menus
used
to
perform
a
high-accuracy
two-port
calibration
without
an
S-parameter
test
set.
This
calibration
procedure
eectively
removes
directivity
,
source
match,
load
match,
isolation,
reection
tracking,
and
transmission
tracking
errors
in
one
direction
only
.
Isolation
correction
can
be
omitted
for
measurements
of
devices
with
limited
dynamic
range
.
(The
device
under
test
must
be
manually
reversed
between
sweeps
to
accomplish
measurement
of
both
input
and
output
responses
.)
The
required
standards
are
a
short,
an
open,
a
thru,
and
an
impedance-matched
load.

OPEN
denes the standard type as an open, used for calibrating
reection measurements
. Opens are assigned a terminal
impedance of innite ohms
, but delay and loss osets may still
be added. Pressing this key also brings up a menu for dening
the open, including its capacitance
.
