ZHANG Meng-lin, LI Nian-qiang, WANG Zheng-Sheng (Sch. of Info. Sci. and Eng., Jian Univ., Jinan 250022,China) Abstract :Develops a virtual instrument laboratory using virtual instrument and network technology based on LAN. It helps students to learn the function of various instruments , and be familiar with sorts of signal processing method ,in order to change the laboratory teaching mode based mainly on theory. Its topology , design principle,design outline,and involved key technology are described in detail .Also in this paper introduced the most complicated experiment module - arbitrary wave generating device in laboratory emphatically and described other experiments briefly. Low cost, flexible configuration, strong capability between individual and computer, high visual degree are testified in laboratory, it has learning practice value and engineering utility value. Key words : virtual- instrument laboratory ; LabWindows/CVI; topology ; arbitrary wave generating device
