Setting
the
Electrical
Length
of
the
T
est
Fixture
After
connecting
the
test
xture
,
you
need
to
enter
the extended
electrical length
of the
xture
.
This
is
required
to
eliminate a
phase shift
error caused
by the
extended electrical
length.
The
analyzer
has
electrical
length
data
for some
xtures as
preset data.
