The paper describes a simple and effective measurement technique for conducted Electromagnetic Interference. This technique is based on the employment of the Hybrid Coupler for measurements of the common mode and differential mode current components. The measurements are accomplished at the input of the apparatus to be tested, in presence of a dummy load. The whole study is completed by an analysis of the Hybrid Coupler, which is accomplished by means the flowgraph method. This procedure has been used since it is particularly tailored in dealing with a complex network. Several experimental tests have been performed which confirm the validity of the proposed technique.
