Abstract:To effectively solve the problems which are large numbers of test components, physical large, high cost of special test component and poor compatibility of the military test equipment in the field of wireless communications test, Synthetic Instrument technology are provided. This paper puts forward that the Synthetic Instrument technology applied to general wireless data transmission test equipment. It discussed the detailed analysis of the functional requirements and the architecture of the software and hardware platform of Synthetic Instrument, the combination and sharing scheme of each function module. It introduced the Synthetic Instrument’s key technology which are applied, and the optimization and promotion in the hardware resource utility, test index and compatibility which provided by the key technology. It helps to achieve the goal of booting the general testing equipment for the development of miniaturization, generalization and low cost.
