The cables connecting avionics equipment are important coupling path for electromagnetic interference. When modeling a cable, the terminal common-mode impedance of the cable is a crucial input parameter. Because the quantity of cables in avionics system is very large, it is beneficial for quickly modeling cables' coupling through improving the test efficiency of cable terminal common-mode impedance. Therefore, a method to quickly test the terminal common-mode impedances of cables is proposed. First, according to the theory of multi-conductor transmission line, the multi-core cable can be equivalent to a single conductor when the common-mode current is analyzed. In addition, a cable bundle can be equivalent to a multi-conductor transmission line, and a vector network analyzer and a current probe can be used to measure the voltage reflection coefficients at two optional positions of each cable. Then, based on the established model of multi-conductor transmission line, the terminal impedance equations are constructed. Finally, the numerical iterative algorithm is used to solve the equations, and the terminal common-mode impedance of each cable is extracted. Compared with the existing methods, the testing efficiency and accuracy are improved.
