In this paper,based on the research of the working principle of RF cable,a set of RF cable electromagnetic shielding efficiency measurement device with frequency range from DC to 30 MHz is designed by using triaxial method.Through the simulation software,the smooth transition and connection between the port,transmission line and transfer interface of the device are optimized,and the remote reflection coefficient of the device reaches more than 0.95.The finished device is tested,and the test results are compared with the simulation results,and the agreement is good.
