Difference (Difference from
previous sample value)
(14) XY-Area
Obtains the area [V2] of an X-Y synthesized waveform.
Calculates the areas enclosed in lines of the waveform on the X-Y screen.
Specifying a range obtains the areas of sections between the range-
specifying cursors.
(15) Integration
Adds all data from the start of
the calculation range. A
negative value is added with
its sign.
<Formula>
SUM: Integration
n: Total number of data
di: "i"th data of the channel
(16) Difference
Obtains the difference
between the current data and
previous data.
Obtains the difference of the
waveform within the range for
calculation and selects the
maximum values.
