© National Instruments | 5-25NI cDAQ-9138/9139 User ManualYou can specify a pulse width. The pulse width is also measured in terms of a number of activeedges of the Source input. You also can specify the active edge of the Source input (rising orfalling).Figure 5-26 shows a generation of a pulse with a pulse delay of four and a pulse width of three(using the rising edge of Source).Figure 5-26. Single Pulse GenerationSingle Pulse Generation with Start TriggerThe counter can output a single pulse in response to one pulse on a hardware Start Trigger signal.The pulse appears on the Counter n Internal Output signal of the counter.You can specify a delay from the Start Trigger to the beginning of the pulse. You also can specifythe pulse width. The delay is measured in terms of a number of active edges of the Source input.You can specify a pulse width. The pulse width is also measured in terms of a number of activeedges of the Source input. You can also specify the active edge of the Source input (rising andfalling).Figure 5-27 shows a generation of a pulse with a pulse delay of four and a pulse width of three(using the rising edge of Source).Figure 5-27.
