REFERENCE
POSITION
sets
the
position
of the
reference line
on the
graticule of
a
Cartesian
display
,
with
0
the bottom
line of
the graticule
and 10
the
top
line
.
It
has no
eect on
a polar
or Smith
display.
The
reference
position is
indicated with
a small
triangle just
outside
the
graticule
,
on the
left side
for channel
1 and
the
right
side
for
channel
2.

RESPONSE leads
to the

response calibration.
This is
the simplest

fastest
accuracy
enhancement
procedure

but
should
be
used when extreme accuracy is not required. It eectively
removes the frequency response errors of the test setup for
reection or transmission measurements
