Threshold Triggering Using DAQ Assistant

[milkyptros]

Hi to all

I am using pressure transducers to acquire pressure signal using the DAQ assistant. Is there any way that I can trigger the acquisition of signals after the pressure is more than a certain value?

Thanks in advance

What sort of device? You need to look at the specs to see the types of triggering that are available for it.

The device that I am using is NI USB-6531

Do you actually mean the 6351? That's a multi-function device with analog triggers. I'm unsure about the DAQ a Assistant. With Help> Find Examples, you can find code that uses the DAQmx functions to setup a triggered acquisition.

Yes, you are right its NI USB-6531.

Thank you Dennis, I will try this
