Research and Development of Dynamic Parameter Test System Based on Virtual Instrument

In order to meet the testing requirements of dynamic signals, the design and realization of dynamic parameter testing andprocessing system based on Virtual Instrument (VI) are discussed in this paper. First, several kinds of VI architectures were com-pared, 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 au-tomatic testing and processing of multi- channel non- electric dynamic signal, decreases the human error, and improves the testing ef-ficiency and precision effectively.
