The AI Start Trigger is configurable as retriggerable. When the AI Start Trigger is configured as
retriggerable, the timing engine generates the sample and convert clocks for the configured
acquisition in response to each pulse on an AI Start Trigger signal.
The timing engine ignores the AI Start Trigger signal while the clock generation is in progress.
After the clock generation is finished, the counter waits for another Start Trigger to begin another
clock generation. Figure 4-31 shows a retriggerable analog input with three AI channels and four
samples per trigger.

Note Waveform information from LabVIEW does not reflect the delay between
triggers. They are treated as a continuous acquisition with constant t0 and t1
information.
