This paper deals with the approximate worst-case test method for testing the insertion loss of the EMI filters. The systems with 0.1 ohm and 100 ohms impedances are usually used for this testing. These measuring systems are required by the international CISPR 17 standard. The ain disadvantage of this system is the 0.1 ohm impedance transformer. The dynamic range for the transformation from the 50 ohms, which is most common matched impedance for the measurement setups, to 0.1 ohm is very large. It is no easy to produce such transformers with his high impedance transformation ratio. These transformers have usually very narrow bandwidth. This paper discusses the alternative system with 1 ohm and 100 ohms impedances. The performance of these systems was tested on several filters and the obtained data are epicted, too. The performance comparison of several filters in several systems is also included. The performance of alternate worst-case system is discussed in the conclusion.
