Measurement Algorithms
The automated measurements are defined and calculated as follows:
Amplitude = High Low
The arithmetic area for one waveform. Remember that one waveform is not
necessarily equal to one cycle. For cyclical data you may prefer to use the cycle
area rather than the arithmetic area.
if Start = End then return the (interpolated) value at Start.
Otherwise,
Area=
ŕ
End
Start
Waveform(t)dt
For details of the integration algorithm, see page B–15.
Amplitude (voltage) measurement. The area over one waveform cycle. For data
not cyclical, you might prefer to use the Area measurement.
If StartCycle = EndCycle then return the (interpolated) value at StartCycle.
