description The invention relates to a source impedance stable network, which is used as a standard load for transmitting electromagnetic interference measurement. Compared with the conventional source impedance stable network, the source impedance stable network is characterized in that a 50-ohm standard load is removed from the source impedance stable network and is replaced by a coupling circuit of which the equivalent input impedance is 50 ohms. The improved source impedance stable network does not measure the electromagnetic interference of a live wire or a zero line independently, but proceeds fromthe definitions of common-mode interference and differential mode interference, uses the coupling circuit to obtain the common-mode interference and the differential mode interference at the same timeon the basis of detecting interference signals of the live wire and the zero line at the same time. The source impedance stable network can be widely applied to measurements of various conduction electromagnetic interferences
