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)
A and B are numbers between 0.0 and RecordLength – 1.0 
If A and B are integers, then:
 
 
where s is the sample interval.
Similarly,
 
 
W(t) is the sampled waveform
Ŵ(t) is the continuous function obtained by linear interpolation of W(t)
A and B are numbers between 0.0 and RecordLength – 1.0 
If A and B are integers, then:
 
 
where s is the sample interval.
