continuous data acquisition from 2 channels

[Ninjatovitch]

Hi,

I wonder how I could acquire signals from 2 channels continuously. I have tried to find a vi example but could not find one. In the vi below, I have copied the same functions that work for a single channel but this does not work.

Best regards,

Try it this way. In your DAQmx Physical Channel control, enter Dev1/ai0:1 for channels 0 and 1.

Hi Adnan,

Thank you very much for your quick help. Sorry if I am asking you this question, did I enter the right channels in the Physical Channel Control of the vi below? Because I can only see the signal from one channel.

Best,

It should be Dev1/ai0:1 as mentioned above where ai0 is channel 0 and ai1 is channel one. They are seperated by a ':' which specifies the range. Have a look at the following:
