Generate pulse train 40kHz

[Wallberg]

Hey!

I want to generate 8 pulses in 40kHz. After the 8 pulses are generated there should be a wait period of 15 ms and then repeat the same process again.  I'm using a myDaq to both generate and aquare the signal. I have accomplished this using the DaqAssistant, but only at 125 ms. Therefore I have tried using the Daqmx blocks,but the loop sending the signal can't get any faster than 20ms, why? 

Best regards.

I'm not an expert at Pulse Generation. (yet)

But I found a post on here the other day about Buffered Generation that might lead you in the right direction.

I'm thinking you might need to "build" your entire pulse train, including the 15ms wait time, into the buffer. 

Good luck.

Thanks! I'll check that out 🙂
