KPCI-3101 — KPCI-3104 Series User’s Manual
The period of the output pulse is determined by the clock input signal. In repetitive one-shot
mode, the internal C/T clock source is more useful than an external C/T clock source; refer to
for more information on the internal C/T clock source.
Using DriverLINX, specify the counter/timer mode as repetitive one-shot, the clock source as
internal, the polarity of the output pulses (high-to-low transitions or low-to-high transitions), the
duty cycle of the output pulses, and the gate type to trigger the operation. Refer to
more information on pulse output types; refer to
for more information on gate types.
NOTE
In the case of a repetitive one-shot operation, use a duty cycle as close
to 100% as possible to output each pulse immediately after the trigger
occurs. Using a duty cycle closer to 0% acts as a pulse output delay.
Ensure that the signals are wired appropriately. Refer to
example.
NOTE
Triggers that occur while the pulse is being output are not detected by
the board.
shows an example of a repetitive one-shot operation using an external gate (rising
edge); a clock output frequency of 1kHz (pulse period of 1 ms), a low-to-high pulse type, and a
duty cycle of 99.99%.
shows the same example using a duty cycle of 50%.
