Y
ou
can
either
set
the
position
of
the
plates
directly
,
or
use
the
circle
application
to
set
the
2"
B
and
2
P
angles
that
dene
the
position
on
the
P
oincare
Sphere
.
In
addition,
using
the
sphere
application,
you
can
vary
the
angles
of
the
/4
and
the
/2
plates
continuously
.
By
varying
the
plate
positions
slowly
,
and
sampling
the
response
of
your
Device
Under
T
est,
you
can
nd
the
maximum
and
minimum
power
levels
,
and
thus
make
polarization
dependent
measurements
.
By
varying
the
plate
positions
quickly
,
and
averaging
over
all
the
states
of
polarization,
you
can
measure
the
response
of
your
DUT
to
a
\depolarized"
signal.
Using
the
P
olarization
Controller
for
P
olarization
Analysis
It
is
also
possible
to
use
the
polarization
controller
to
analyze
the
polarization
of
a
signal.
T
o
do
this
you
attach
your
incoming
signal
to
the
/2
connector
,
and
attach
your
power
meter
to
the
P
ol
connector
.
