"Hi, how to separate 3 signals getting from DAQ Assistant? I used the split signal but it looks as the signals are mixed.. Any help please?I appreciate your help, since it is an urgent .

I attached my VI

Could you attach a pic block diagram and front panel of your VI??

Could not open your VI as your version of LabVIEW must be higher than 7.1

Also, see if this recent post helps you

Thanks!

Here you go.

You can see that the SYNC signal is right , but the another 2 signals got from 2 sensors different are mixed.

Thanks in advance.

They might still be right.

Just observe the Y axis scale on all teh graphs. what do you see??

on the common graph, they are all on a scale of 0 to 5

where as on individual graphs, they are on a scale of 0 to 0.8 and o to 1.2

Remove auto scale y axis option and set all graphs  to a common Y axis and observe

Hope this helps

Thanks for your quick reply.

But I already changed the Y axis scale and It looks with the same problem. Could you see the attached file please? In the graphs "acceleration signal sensor 1 and 2", you can see the there is a peak when  at the same point  when labview is represented the SYNC signal. So, the signal provenient from the 2 acceleration sensor are bad signals from the very beginning, it means , the first waveform graph, represent the data acquisition am doing through DAQ assistant.BUt when I moved the acceleration sensor, it showed as a noise...

Could you please, check the attached file please? thanks

Marieta,

From your pic of block diagram, I cannot derieve a better solution.

I cannot open your vi, see and suggest better ( coz I am currently working on LabVIEW 7.1)

Sorry bout that

But definitely, someone else will come up with a better answer.

Hold on
