Abstract:
Based on the analysis of the mechanism of EMI noise generation in PCB circuit,the PCB differential and the common mode radiation interference model are established. This paper,by using the near field probe and the frequency spectrum instruments,presents the principles and operational methods that can determine the EMI radiation noise sources and roughly their corresponding positions.?After the rough position of radiation source is determined by the field probe,and the radiation source device,and the?circuit characteristics with the radiation model are combined,the thread of the radiation noise suppression program is developed. This paper with above ideas proceeds with the correctional analysis as regard to sputum aspirator,and subsequent radiation test by standard 3 m anechoic chamber built by German company R&S,proves the effectiveness of the correctional plans and approaches presented in this paper.
