Description
Rise time
Fall time
Calculates a A%-to-B% rise time (or a B%-
to-A% fall time; unit: s) based on the 0%
and 100% levels based on a histogram
(frequency distribution) of acquired
waveform data.
The instrument calculates a rise time (or
fall time) of the first rising (or falling) slope
that appears in acquired waveform data.
When a range is specified with section
cursors, the instrument calculates a
rise time (or fall time) of the first rising
(or falling) slope that appears between
cursors.
You can specify values of A and B in
percent. The values of A and B varies
along with each other. When the value of
A is 5%, the value of B is specified at 95%;
when the value of A is 30%, the value of B
is specified at 70%.
Settings: Rise time (A% to B%) and
Fall time (B% to A%) values in

Area
Method : Total
Calculates an area by subtracting an area (unit:
V·s) enclosed by the zero-level (zero-potential)
line and the negative-amplitude part of a signal
waveform from an area (unit: V·s) enclosed
by the zero-level (zero-potential) line and the
positive-amplitude part of the signal waveform.
When a calculation range is specified with
section cursors, the instrument calculates an
area between the cursors.

Area
Method :
Absolute value
Calculates an area value (unit: V·s) enclosed by
the zero-level (zero-potential) line and a signal
waveform.
When a calculation range is specified with
section cursors, the instrument calculates an
area between the cursors.
