Oscilloscope Reference Measurement algorithms

Rise Time

RMS

Amplitude (voltage) measurement. The true Root Mean Square voltage.

If Start = End then RMS = the (interpolated) value at Waveform[Start].

Otherwise,

For details of the integration algorithm, see below.

Integration Algorithm

The integration algorithm used by the instrument is as follows:

W(t) is the sampled waveform

Ŵ(t) is the continuous function obtained by linear interpolation of W(t)
