How to implement DAQ

[data collection]

I am using national instrument card for data aqusition and I have following question. In my programm I need to collect dat each time I ask to get the latest dat. Here with this I am sensiting my current VI. What it does is collecting 1000 data points each time when I ask it to do so, but I am not sure is it is getting the lattest data. I need to get 1000 data points (lates data points) and average. In here I am not sure if I get the latest data or not?

Greetings,

Your application is continually starting a finite acquisition of 1000 samples and then reading the oldest 10 samples. I would suggest that you take a look at the example Acquire N Scans.vi. This example installs with LabVIEW and demonstrates the proper structure of a finite acquisition VI.

Good luck with your application.
