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.
If  =  then return the (interpolated) value at .
