Abstract: In a complex electromagnetic environment, how to test electronic information equipment is a complex system problem. Meta-synthesis is an effective method to analyze and solve this problem. This method integrates the advantages of reductionism and holism, and gradually develops into a mature system engineering methodology. On the basis of the summary of the method, the generalized problem of electronic equipment test is researched. The complexity of electronic information equipment test in complex electromagnetic environment is studied. The shortage and drawback of the traditional testing method are pointed out. Finally, this paper discusses the implementation process of electronic equipment test by using meta-synthesis method, which provides a new and effective approach for testing electronic information equipment.
