Research on Network Virtual Laboratory System

The virtual instrument’s gradually developing into the direction to network make Network Virtual Laboratory(NVL) becomes an important mode of laboratory construction. Starting from analysis on characteristics of virtual laboratory system, the paper carries through overall design on network virtual laboratory system, and designed the structure of system website and constitutes in detail. Then, the main functions of the NVL were discussed. The frequency characteristic measurement experiment based on NVL was designed to lay foundation for practical application of NVL.
