Conguring the Numerical Calculation Settings
4
Click the [Area] box, and then choose an option for a calculation range.
You can specify a calculation range for each calculation.
Whole
Makes calculations using whole waveforms.
A_B Makes calculations using waveforms between trace cursors A and B.
C_D Makes calculations using waveforms between trace cursors C and D.
Choosing [A_B] or [C_D] allows you to specify the calculation range with the trace cursors on the waveform
screen. When the instrument does not acquire any waveforms, perform another measurement and specify a
range. Doing so allows you to make calculations using data acquired within the specied range from the next
measurement.
5
Click a calculation target channel.
The channel selection screen appears.
Refer to “Calculation target channels and setting contents of calculation conditions for each calculation type”
(p. 139).
6
Set calculation conditions.
Refer to “Calculation target channels and setting contents of calculation conditions for each calculation type”
(p. 139).
7
Execute calculation.
(To calculate existing data)
Click [Execute].
(To automatically make calculation after measurement)
Click the start icon.

[Accumulation] setting,
set [Method].

Target channel
(Analog, logic, waveform
calculation)
Allows you to specify
calculation target
channels.
Level*
The instrument makes
calculations using
values based on a
period of time when a
waveform crossed the
level specied here. No
setting is available for
logic channels.
Slope
No slope can
be specied for
calculating the
duty ratio.
Makes calculations
using values based on
a period of time when a
waveform crossed the
specied level in the
positive direction.
Makes calculations
using values based on
a period of time when a
waveform crossed the
specied 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
specied level.
Only if a waveform does
not cross the level again
within the specied 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
specied range.
Average Calculates the
average, maximum, or
minimum value for each
parameter within the
specied 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 signicant gures can be set (a value to 10 signicant gures can be set for a
time of the level at time setting).
