TEST
(NA)
Description
This test
applies the
RF OUT
signal to
the 4395A
R
input
and
either
the
A
or
B
input
through
a
p
o
w
er
splitter.
It
then
measures
the
magnitude
ratio
and
phase
of
the A/R
and
B/R
measuremen
ts.
The magnitude
ratio frequency
response
is measured
as
the
deviation
from the
ideal
magnitude
ratio
v
alue
of
0
dB.
The
phase
frequency
resp
onse
is
measured
as
the
deviation
from
linear
phase.
