A Comparison Study on Conducted Emission Test in International EMC Standards

This paper discusses about the need for conducted emission test (CE) which is a common electromagnetic compatibility (EMC) requirement for all the electronic products manufactured in military, civilian and automotive industries. International EMC standards in each of these industries impose CE requirement on the products to ensure their compatibility with other products which are sharing the common power source network. It is observed that the test specifications in each of these standards vary considerably. Various parameters of CE test in Mil-Std-461G, CISPR 11 and CISPR 25 standards are studied and compared to aid EMC engineers in conducting the test effectively.
