Multi Channel Data Acquisition using PXI-6143

Morover the physical channel is set to "PXI1Slot2/ai0", instead of "PXI1Slot2/ai0:1"

Sorry my expranation is not enough.

I want to display the signals of ai0 and ai1 on different graph at same time.

And later, I want the two signal to trigger and acquire.

Your explanation was enough. You've been told what you did incorrectly. Please make the corrections and repost if necessary.

I want to multi-channel DAQ with analog triggering.

As the previous step, I had been able to acquire one channel data, trigger to one channel data.

So as the next step, I want to acquire two channel data at the same time.

 

The attached code can sample two physical channel at the same time and display on same graph.

But I think it is necessary to separately get the two data for triggering.

 

How can I get two sampled data separately?

Your board only supports digital triggering. 

 

In order to separate the data into channels, you just use the Index Array function.

Hi Dennis_Knutson!

Thank you for the advice.

 

Using Index Array VI, I could acquire and save two sampled data separately (as attached code).

I think multi-channel DAQ with analog triggering is realized by connecting the wire from Index Array to analog triggering SubVI.

The SubVI for one-channel data I had alread made.

I will try it.

 

Thank you very much!

Dear Dennis_Knutson!

 

I have a trouble about multi channel DAQ treated in this thread and posted the new thread(http://forums.ni.com/t5/LabVIEW/Multi-Channel-Data-Acquisition-using-PXI-6143/m-p/2675463).

 

I'm glad if you give advices.
