Description
X-Y area
Method :
Trapezoidal
approximation
Calculates an area (unit: V
2
) enclosed by an XY composite curve using the trapezoidal
approximation method. 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).

Time to level
Searches a calculation range from the beginning
for the time when a signal crossed the specified
level and calculates a period of time from a
trigger point to a point searched for.

Level
Level at time
Calculates a level when the specified time has
elapsed from a trigger point.
You can also specify a time based on previously
calculated results.

Pulse width
Calculates a pulse width based on a time lag
between the time when a waveform crossed
the specified level in the positive (or negative)
direction and the time when it next crossed the
specified level in the opposite direction.
