In order to meet the testing requirements of dynamic signals, the design and realization of dynamic parameter testing and processing system based on Virtual Instrument (Ⅵ) are discussed in this paper. First, several kinds of Ⅵ architectures were compared, and the scheme of programmable conditioning and distant sampling was proposed according to the practical requirements; then,the system's software and hardware realization as well as the channel trigger and calibration was presented. The system realizes automatic testing and processing of multi-channel non-electric dynamic signal, decreases the haman error, and improves the testing efficiency and precision effectively.
