| Abstract: | Aiming at the current mode of delivery inspection of lineside electronic unit and tran-sponder equipment in mass production,a scheme of automatic test system based on virtual in-strument technology is proposed,in which the virtual instrument is used in background program-ming to analyze and calculate the characteristics of the signals including eye map.Meanwhile,PX1 high speed bus test equipment is used to build a highly integrated test platform so that multi-ple calculations can be conducted to achieve analysis results based on once signal acquisition.This scheme is simple in operation and accurate in measurement can further eliminate human errors and improve efficiency. |
