removes
directivity
errors
of
the
test
setup
in
forward
and

directions
removes
source

errors
of
the
test
setup
in
forward and

removes
load
match
errors
of
the
test
setup
in
forward and

removes

errors
of
the
test
setup
in

removes
frequency
response
of
the
test
setup
in
forward
and

Note
This
is the
most accurate
error-correction procedure
.
Since
the
analyzer
takes
both
forward and
reverse
sweeps
,
this
procedure
takes
more
time
than
the
other
correction procedures
.
