Data acquisition

Hi there,

I have many sensors to communicate with using labview, and one of which is an audio sensor. for the audio sensor i intend to use the sampling frequency of 44100Hz and for the other sensors a sampling frequncy of 1000Hz. is it poosible to use the same DAQ assistant? if not, how can i go about it.

Regards,

tjuy

For different sampling rates, you will need different devices.  Put all of the channels at 1kHz on one DAQ and the channels at 44.1kHz on a second DAQ.  You will then also need two use multiple DAQmx tasks, one per DAQ.  Each task uses a different DAQ Assistant.

Hi everyone!

I was wondering if somebody could help with this one. I have got audio signal from four sensors that I want to save at the of a while loop, I tried using build array vi then to write to spreadsheet vi, but whenever I opened the file I could only see two rows one column of the data. And I expected to see four columns of numerous rows. Please advice on such a problem. Thanks.
