user defined You can set the unit of measure for the upper, middle, and lower thresholds
to either % (percent) or Volts.Percent is calculated from the top-base values,
and you can set the percent values from 0 25 percent to +125 percent in
0.1 percent increments.Volts lets you set the thresholds to particular voltage
values regardless of the top-base values.You can set the voltage values from
0 1.00 GV to +1.00 GV in increments determined by the voltage range you
are in. For example, if the upper threshold is set to 110  V, you can change
the threshold in 1  V increments. However, if the threshold is set to 110 MV,
you can change the threshold in 1 MV increments.
The upper threshold value is always greater than the value of the middle
threshold, and the middle threshold value is always greater than the value of
the
lower
threshold.
The
instrument
will
not
allow
a
threshold
to
cross
over
the adjacent
threshold.
If
the
threshold you
are using
for
the
measurement
is
not
positioned
on
the
waveform,
then

The
result
is
that
the

of
the

is
increased,
because
