With the [Area] or
[Accumulation] setting,
set [Method].
(Total

Calculates an area or
accumulation according
to the method you
specify here.

Target channel
(Analog, logic, waveform

Allows you to specify

Level*
The instrument makes
calculations using
values based on a
period of time when a
waveform crossed the
level specied here. No
setting is available for
logic channels.
Slope
No slope can
be specied for
calculating the
duty ratio.
Makes calculations
using values based on
a period of time when a
waveform crossed the
specied level in the
positive direction.
Makes calculations
using values based on
a period of time when a
waveform crossed the
specied level in the
negative direction.
Filter(samples)
(Off
, 10 to 10,000)
Allows you to enter
duration used to
determine that a
waveform crosses the
specied level.
Only if a waveform does
not cross the level again
within the specied lter
duration after it has
crossed the level, the
waveform is considered
to have crossed the
level.
This is useful to
eliminate false level-
crossing events caused
by noise.
Stat. Top
Detects a value
obtained rst from the
beginning within the
specied range.
Average Calculates the
average, maximum, or
minimum value for each
parameter within the
specied range.
Max

*: The range you can specify are between −9.9999E+29 and −1.0000E-29, 0, and between +1.0000E-29 and
+9.9999E+29. A value to ve signicant gures can be set (a value to 10 signicant gures can be set for a
time of the level at time setting).

Target channel
(Analog, waveform
calculation)
Allows you to specify
calculation target
channels.
Time (%)
(5%→95%
to 30% →
70% or 95% → 5%
to
70%→30%)
Allows you to specify
which part of a
waveform between the
upper and lower limits is
used for calculating the
rise time (or fall time).
A rise time (or fall time)
is calculated based on
the percentage, which
is specied here, of
the range between the
upper and lower limit
values.
Stat. Top
Detects a value
obtained rst from the
beginning within the
specied range.
Average Calculates the
average, maximum, or
minimum value for each
parameter within the
specied range.
