Simple Pulse Generation
Refer to the following sections for more information about the X Series 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 can also specify the active edge of the Source input (rising or
falling).
Figure 7-27 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 7-27. Single Pulse Generation
Single Pulse Generation with Start Trigger
The 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 route the Start Trigger signal to the Gate input of the counter. You can specify a delay
from the Start Trigger to the beginning of the pulse. You can also specify the pulse width. The
delay and pulse width are measured in terms of a number of active edges of the Source input.
After the Start Trigger signal pulses once, the counter ignores the Gate input.
