Table 7-6 and Figure 7-34 detail a finite implicit generation of three samples.
Figure 7-34. Finite Implicit Buffered Pulse Train Generation
Continuous Buffered Implicit Pulse Train Generation
Continuous buffered implicit pulse train generation creates 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
Finite buffered sample clocked pulse train generation creates 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.
Note When the last sample is generated, the pulse train continues to generate with
these specifications until the task is stopped.
