Calculation type
Calculates the A%-to-B% rise time (or the
B%-to-A% fall time) (unit: s) based on the
0% and 100% levels, which are calculated
based on the histogram (frequency
distribution), of the acquired waveform
data.
The rise time (or fall time) of the first rising
(or falling) slope in the acquired waveform
data is calculated.
When the range is specified with section
Rise time cursors, calculates the rise time (or fall
Fall time
time) of the first rising (or falling) slope
appearing between the cursors.
The values of A and B can be specified
(unit: %). The values of A and B varies
along with each other. When the value of
A is 5%, the value of B is specified to 95%;
when the value of A is 30%, the value of B
is specified to 70%.
Settings:
Calculates the standard deviation of the waveform data.
σ = √
Standard deviation
Calculates the area by subtracting the area (unit:
V·s) enclosed by the zero-level (zero-potential)
line and the part where the amplitude of the
signal waveform is negative from the area (unit:
V·s) enclosed by the zero-level (zero-potential)
line and the part where the amplitude of the
signal waveform is positive.
Area
When the range is specified with section cursors,
Method: Total
calculates the area between the cursors.
S =
Calculates the area value (unit: V·s) enclosed by
the zero-level (zero-potential) line and the signal
waveform.
When the range is specified with section cursors,
Area
calculates the area between the cursors.
