procedure
eectively removes
the same
frequency response
errors
as the
response
calibration.
In
addition,
it
eectively
removes
the isolation
(crosstalk)
error
in
transmission
measurements
or the
directivity
error
in
reection
measurements
.As
well
as
the
devices
required
for
a
simple
response
calibration, an
isolation
standard
is
required.
The
standard
normally
used
to
correct
for
isolation
is
an
impedance-matched
load
(usually
50
or
75
ohms).
Response
and
directivity
calibration
procedures
for
reection
and
transmission
measurements
are
provided
in
the
following
pages
.
