Seeing as the samples began being recorded at index 27 within the CSV output, that
value has to be added to the trigger cycle tag value as an offset to get the exact cycle
of where the trigger condition occurred, which would be at index 539.
Sample Rate is the number of samples in a single cycle at a nominal 60 Hertz. For
example, at a sample rate of 512, there are 512 samples in a single nominal (time
locked) cycle. Note that this means that there are 512 samples every 16.6~ms.
The sample rate also affects the duration of the capture. Since the capture records a
fixed number of samples, the number of cycles recorded is dynamic based off the
sampling rate. For example, at 512 samples per cycle, 4 cycles can be record. At 32
samples per cycle, 64 cycles can be recorded.
To calculate the duration of the capture, in milliseconds, the following formula must
be applied:
• number of samples is number of samples in the capture per channel (2048 sam-
ples)
For example, given a sample rate of 1024, the duration would be:
( (2048 * 1000) / (1024 * 60) ) = ( 2048000 / 61440 ) = 33.333 ms
