This testing system is based on LabVIEW. This study covers signal generation, signal analysis and processing, and case studies. First, the structural frame of this system and the design procedure of main programs are simply summarized; then the installation steps of the PCI-9111HR DAQ card and virtual signal generator are ex- plained in detail, and the functions of signal analysis and processing are described. Finally, two examples about the virtual instrument is given, and the design process and the results are analyzed. It is shown that this system can low- er the experimental cost and improve utilization ratio.
