Timing measurement. The duration of a burst.
1. Find on the waveform. This is .
2. Find the last (begin the search at and search toward
). This is . This could be a different value from

3. Compute = –
Amplitude (voltage) measurement. The mean over one waveform cycle. For
non-cyclical data, you might prefer to use the Mean measurement.
