Because
both
Channel
1
and
Channel
2
can
measure
B/R
magnitude
ratio,
you
may
measure
B/R
simultaneously
on
both
channels
at
different
scale/division settings.
Calibrate
both
channels as described
above
for insertion loss
or
gain.
To
measure
magnitude
and
phase simultaneously, use
Channell
for
magnitude
and
Channel
2 for phase.
If
you decide
to
use
Channel
2 for
both
magnitude
and
phase
measurements, switching between
B/R
and
PHASE
B/R,
calibrate
magnitude
first as described above then
do
not
change
Channel
2
OFFSET
during phase calibration.
