Wherein,
i
x
is the measurement result of the i
th
point being measured;
n
is
the total number of points being measured.
9. Vrms-1: the root mean square value of the voltage values of the waveform
points (relative to the GND) within a single period. The calculation formula is as
shown above.
10. Overshoot: the ratio of the difference of the maximum value and top value of
the waveform to the amplitude value.
11. Preshoot: the ratio of the difference of the minimum value and base value of
the waveform to the amplitude value.
Area Parameters
1. Area: the horizontal axis denotes time and the vertical axis denotes waveform
amplitude. The oscilloscope calculates the area of the waveform (namely the
integral of the time and amplitude). The unit is volt-second. The area of the
waveform above the zero reference (namely the vertical offset) is positive and
the area of the waveform below the zero reference is negative. The area
measured is the algebraic sum of the area of the waveform within the current
measurement range.
2. Per.Area: period area; the horizontal axis denotes time and the vertical axis
denotes waveform amplitude. The oscilloscope calculates the area of the
waveform (namely the integral of the time and amplitude) within a single period.
The unit is volt-second. The area of the waveform above the zero reference
(namely the vertical offset) is positive and the area of the waveform below the
zero reference is negative. The area measured is the algebraic sum of the area
of the waveform within a single period.
