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.
