Software Development Environment
NI LabVIEW
NI LabVIEW is a graphical development environment for creating flexible and scalable test, measurement, and control applications rapidly and at minimal cost. With LabVIEW, engineers and scientists interface with real-world signals, analyze data for meaningful information, and share results and applications. Regardless of experience, LabVIEW makes development fast and easy for all users.
Data Acquisition Platform
NI Educational Laboratory Virtual Instrumentation Suite (NI ELVIS)
The NI Educational Laboratory Virtual Instrumentation Suite (NI ELVIS), based on LabVIEW, is a design and prototype environment for university science and engineering laboratories. NI ELVIS consists of virtual instruments (VIs) based on LabVIEW, a multifunction data acquisition device, and a custom-designed benchtop workstation and prototype board. This combination provides a ready-to-use suite of instruments for all educational laboratories.
