Selecting
the
Input
The
analyzer
uses
three
inputs
for
network
measurements
(R,
A,
and
B).
Usually
,
the
R
input
accepts
the
RF
OUT
signal
directly
,
the
A
input
receives
the
re ection
signal
from
the
DUT
,
and
the
B
input
receives
the
transmission
signal
through
the
DUT
.
This
example
assumes
you
are
using
the
T/R
test
set.
Therefore
,
because
you
are
going
to
measure
the
transmission
characteristics
of
the
DUT
,
select
B/R
to
measure
the
ratio
of
B
and
R
inputs
.
When
you
use
the
S-parameter
test
set,
you
can
measure
the
forward
and
reverse
characteristics
of
a
2-port
device
without
reconnecting
the
inputs
.
In
that
case
,
select
S
21
for
a
transmission
measurement
in
the
forward
direction.
In
the
MEASUREMENT
block,
