Finite Implicit Buffered Pulse Train GenerationContinuous Buffered Implicit Pulse Train GenerationThis function generates a continuous train of pulses with variable idle and active times. Insteadof generating a set number of data samples and stopping, a continuous generation continues untilyou stop the operation. Each point you write generates a single pulse. All points are generatedback to back to create a user defined pulse train.Finite Buffered Sample Clocked Pulse Train GenerationThis function generates a predetermined number of pulse train updates. Each point you writedefines pulse specifications that are updated with each sample clock. When a sample clockoccurs, the current pulse (idle followed by active) finishes generation and the next pulse updateswith the next sample specifications.Note When the last sample is generated, the pulse train continues to generate withthese specifications until the task is stopped.Table 5-7 and Figure 5-33 detail a finite sample clocked generation of three samples where thepulse specifications from the create channel are two ticks idle, two ticks active, and three ticksinitial delay.Table 5-6.
