摘　　要：GJB 5186.7-2005是数据总线部件的通用测试方法,是数据总线部件设计验证和生产测试的主要依据。但实际应用中发现在对数据耦合器进行共模抑制项性能测试时,该标准给出的测试结构连接图可能存在错误,故作出讨论和更正。The GJB 5186.7-2005 is the universal test method of the data bus components. And it is the important resort to validate the design of the data bus components and to test during the manufacture. However, during the practical application, the authors find that there may be an error in its diagram for the test of the common mode rejection ratio. So,the error is discussed and corrected in this paper.
