Counter Output Applications
The following sections list the various counter output applications available on the cDAQ
chassis:
• Simple Pulse Generation
• Pulse Train Generation
• Frequency Generation
• Frequency Division
• Pulse Generation for ETS
Simple Pulse Generation
Refer to the following sections for more information about the cDAQ chassis simple pulse
generation options:
• Single Pulse Generation
• Single Pulse Generation with Start Trigger
Single Pulse Generation
The counter can output a single pulse. The pulse appears on the Counter n Internal Output signal
of the counter.
You can specify a delay from when the counter is armed to the beginning of the pulse. 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 active
edges of the Source input. You also can specify the active edge of the Source input (rising or
falling).
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).
