NOTE
(13) Area value
Calculates the area bordered by the signal waveform and the zero position
(potential 0 V).
If the A/B cursors (vertical, trace) are used, the area between the cursors is
calculated.
Equation
(14) X-Y area value
Calculates the area (V
2
) after X-Y plotting.
The waveform is plotted on the X-Y screen, and the area enclosed by the
plot lines is calculated.
In single, dual, or quad screen, the A/B cursors (vertical, trace) can be used
to specify the range (see Section 11.2.) for X-Y plotting and area calculation.
On the X-Y screen of the memory recorder function, it is not possible to
specify the range with the A/B cursors.
Depending on the signal waveform, values for parameters (8), (9), (10), and
(11) may not be displayed.
When the scaling function is used, scaling is first applied to waveform data,
and then the parameters are calculated. The parameter unit is determined by
the scaling unit ( see Section 9.7).
