Continuous Buffered Implicit Pulse Train Generation

This function generates a continuous train of pulses with variable idle and active times. Instead
of generating a set number of data samples and stopping, a continuous generation continues until
you stop the operation. Each point you write generates a single pulse. All points are generated
back to back to create a user defined pulse train.

Finite Buffered Sample Clocked Pulse Train Generation

This function generates a predetermined number of pulse train updates. Each point you write
defines pulse specifications that are updated with each sample clock. When a sample clock
occurs, the current pulse (idle followed by active) finishes generation and the next pulse updates
with the next sample specifications.
When the last sample is generated, the pulse train continues to generate with
Note
these specifications until the task is stopped.
Table 5-7 and Figure 5-33 detail a finite sample clocked generation of three samples where the
pulse specifications from the create channel are two ticks idle, two ticks active, and three ticks
initial delay.
