| Abstract: | This paper introduced a virtual measurement system which was designed to test volt-ampere characteristics curve and conduction resistance of LED. The system collected data by a data collection card, then realize data processing and operation by the Labview, and display the result in the screen at last. It realizes the function of tradition hardware by software, reduces the instrument cost, and has the advantage of convenient use and flexible links. |
