Showing 2 or more AInputs

[vedran]

Hi people,

what i want to do is to simultaneously show 2 analog input signals, each in separate chart or wave, and the cross-correlation of the both signals in one other chart. (3 charts in loop)

so i do it on this way: for each signal one DAQ-Assist. 'data' from DAQ-assist to their chart/wave. problem: with one DAQ-Assist in loop there is no any problem. but if i put the second DAQ-assist, then the first DAQ-assist shows nothing in their chart. i mean, i see just chart is working, the second is inactive.

thanx

Hello Vedran,

You won't be able to use two analog input DAQ Assistant VIs at the same time. This is because each DAQ Assistant is going to be competing for the same resource. That is why it looks like you're only getting data from one of the DAQ Assistants.

You will want to use one DAQ Assistant, but configure that DAQ Assistant to acquire from two channels. You can then split the individual signals coming from the single DAQ Assistant and plot both on individual waveform graphs.

This should work for you.
