The invention discloses a new method for testing the clamp effect in a dual-port-removed network. According to the method, a whole clamp system is measured through a vector network analysis instrument, the chain shape scattering parameter of a tested piece is obtained by converting the S parameter into the chain shape scattering parameter and through network cascading and matrix operation, the chain shape scattering parameter is converted into the S parameter, and then the true value of the tested piece can be obtained. The measurement process of a non-standard connector device is effectively simplified, the S parameter of the de-embedded tested piece can be rapidly obtained in real time, and therefore the implementation difficulty and complex steps in a traditional method are avoided. In addition, when the method is adopted, no calibration piece of a non-standard connector needs to be manufactured, no complex and time-consuming modeling and simulation needs to be conducted, the method can be programmed to and embedded in the vector network analysis instrument, and therefore the measurement result can be rapidly displayed in real time, and large-scale production and testing are facilitated.
