Is it possible to generate a single pulse in a counter output channel with NI-DAQmx?

Hi,

I want to generate a single pulse in a counter output channel with NI-DAQmx:

everything works fine for a continuous pulse with a given duration and also for a 2 scan generation:

start(dqPulseOut,"NumScans",2);

However, "NumScans" cannot be set equal to 1 and when I try:

write(dqPulseOut,1)

I get the error message: "Use start to initiate operations when counter output channels are configured".

Looking at the NI-DAQmx documentation, I found:

"When generating pulses, you can generate either a single pulse, a finite pulse train, or a continuous pulse train"

i.e., it looks possible from the NI-DAQmx point of view.

So, does anyone know if it is possible to perform a single pulse generation using a counter?

Thank you very much for your time!

"You can accomplish this same behavior with a single counter is by setting up a continuous pulse output task with a start trigger and a pause trigger."
