Greetings,
The PCI-6031E can handle single or double buffered acquisitions. The two best sources for examples and instructions are LabVIEW itself and our web site. Go to the "Help -> Find Examples" pull-down menu in LabVIEW to search for shipping examples. Look in the folder "Hardware Input and Output -> DAQ -> Analog Input -> General." Here you will find many analog input examples. Specifically, you should pay attention to the ones with "buffered" in the title.
In addition to LabVIEW itself you will find our web site's Developer Zone extremely useful.
