In order to realize the efficient and accurate test of electronic tags, this thesis presents a new type of automatic test device for electronic tag based on nearfield RF communication technology. The system applies ARM7 mierocontroller as the main processor, includes data storage module, digital signal processing module, signal generator, signal acquisition module, communication interface module, the system also applies DDS components as sweep signal generator, thus achieve ultra -high precision frequency control. Meantime, the system is programmed and debugged through embedded software to realize testing automatization for quality parameters of electronic tag in the production process. Finally, through the laboratory test and the actual measurement by manufacturers, the auto- matic testing system can meet the test requirements of tag manufacturers in aspects such as function design, meas- urement accuracy and operation stability, and greatly improves the production efficiency of the enterprise and has certain practical value.
