Abstract: 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) technology are discussed in this paper. First, several kinds of VI architectures were compared, and the scheme of programmable conditioning and distant sampling was proposed, which met the practical requirements; then, the system’s software and hardware realization was presented as well as the channel trigger and calibration. The system realizes the automatic testing and processing of multi-channel non-electronic dynamic signal, and the human error is decreased, meanwhile, the testing efficiency and testing precision are improved effectively.
Keywords: virtual instrument; dynamic signal; automatic testing system
