Asynchronous Acquisition with High-Speed Digitizer
Print
This VI illustrates how to get started with an asynchronous acquisition using an NI high-speed digitizer card. In this context, "asynchronous" means that the data acquisition happens in the background and LabVIEW is free to perform other tasks while the digitizer hardware is busy acquiring data.
NIScope Initiate is used to start the acquisition. 10 times each second, the VI call niScope Check Acquisition Status to see if all the requested data has been obtained. If not, the loop continues. If it has, the data is sent to a graph.
Inside of the while loop is a comment prompting the user to enter some code to be executed as the scope acquires data -- you can put whatever sort of operation you would like here. Right now all the loop does is toggle the "Looping" light on and off to show that the acquisition is asynchronous.
