The invention provides a dual-port electrical appliance transmission parameter acquiring method and system. An impedance parameter of a dual-port electrical appliance in a low-frequency band is obtained by means of an impedance analyzer. A scattering parameter of the appliance in a high-frequency band is obtained by means of a network analyzer. A transmission parameter of the appliance is determined according to the impedance parameter and the scattering parameter. The method and the system can obtain the impedance parameter of the low-frequency band by means of the impedance analyzer and the scattering parameter of the high-frequency band by means of the network analyzer and can determine the transmission parameter according to the impedance parameter and the scattering parameter, thereby solving the problems that during the process of obtaining electrical appliance transmission parameters, for low frequency situations, instrument test frequency may not cover the low frequency or accurate transmission parameters in low-frequency bands may not be obtained. The method and the system can obtain accurate transmission parameters of the dual-port electrical appliance in the low-frequency and high-frequency bands.
