simultaneous aquire ch0-4 w/ 9237

[dennisa]

I could not find an example could to simultaneously aquire data from this device. I have written a .vi that will aquire data from one channel at a time which works great but I now need to read all 4 channels at once could someone provide me with a simple sample code to do something like this.

Thanks in advance

The 9237 is designed for simultaneous sampling. Is it possible for you to post your code?

Here's my code to read and capture 1Ch.

You need to change the Physical Channel control to Dev1/ai0:3 and select Analog -> Multiple Channels -> Multiple Samples -> 1D Waveform for DAQmx Read. Have a look at some of the examples in the Example Finder as well (Help -> Find Examples)

I'll give it a try. Thanks for the quick response.

I was aware of the need to change the DAQmx Read to "Analog -> Multiple Channels -> Multiple Samples -> 1D Waveform" but did not know you could specifyPhysical Channels in such a manner
