The Design of Teaching Experiment System Based on Virtual Instrument Technology

In the paper, a set of teaching experiment system based on virtual instrument technology is developed. Because the current experimental teaching system in technological college faces many important challenges, for example, the equipment gets obsolete, and the cost to construct or maintain the laboratories becomes higher, etc. Therefore, it is essential to improve the current teaching experimental system effectively. In the system, LabVIEW software serves as the development platform, and the external data acquisition is realized by DAQ card. This system can apply to the signal testing technology courses, so the researchers can simulate the signal system response, digital filters, signal generators, oscilloscopes and signal processing experiments, and the operation result can be stored, shown, or printed.
