1+2 Gain
Curves
(optional)
The
variable
gain
curve
is
displayed
for
both
channels
for
the
acquisition
parameters
set. The
center
line
is
at inverse
gain
1.75
(e.g.
1.75
V/div
total
gain
for
fixed
gain
at 1
V/div)
and
vertical
units
are
0.25/div.
So
the
top
border
is
at 2.75
and
the
bottom
at
0.75.
Horizontally
the
curve
goes
from
DAC
-8
V
at
the
left
to
0 V
at
the
right.
The
curves
should
be
smooth
and
go veil
above
the
inverse
gain
2.5
and 1.0
limits
indicated
,
where
the
variable
gain
is
at .4 and
1.,
see
Figure 3.
