Description
Area
Method
:
Positive
(Only the
positive-
amplitude part)
Calculates an area enclosed by the zero-level
(zero-potential) line and the positive-amplitude
part of a signal waveform.
When a range is specified with section cursors,
the instrument calculates an area between the
cursors.

X-Y area
Method :
Coordinate
method
Calculates an area (unit: V
2
) enclosed by an XY composite curve. The instrument
calculates an area enclosed by the lines as illustrated below. An area can be calculated
even when no XY composite curve is displayed.
You can specify a calculation range on a horizontal-axis (time-axis) waveform of each
channel using section cursors. The instrument calculates an area of an XY composite
curve within the specified range (you cannot directly specify a range on an XY waveform
using section cursors).
See “2.1 Reading Measured Values (Trace Cursors, Horizontal Cursors)” (p. 30).
