generating 2 different pulses from one channel

[Thomas2601]

I'm trying to use DAQmx to generate 2 pulses. I need each pulse to have a different duration. I have tried using two different channels to do this, but when I connect them together the signals interfere with each other. I think I need to use one channel therefore to generate a pulse of a set time, and then another pulse of a different time. Does anybody know if this is possible or how to do it?

Hi Thomas,

this should be possible - but you need to supply more information!

Which hardware?

Do you need the pulse on one digital output or do you need two different DO channels?

Which timing resolution we are talking about? Which timing precision?

Thanks for the response.

I'm using an NI PCI 6071E card. The pulses need to be on one channel, ideally one counter output channel. Each pulse will be around 1ms. Hope that helps.

Hi Thomas, 

You could try this example from the community for generating single pulses, and generate the two individual pulses seperately.
