Research on the triaxial measurement method to evaluate the shielding attenuation of a coaxial connector

In order to achieve the accurate and efficient measurement of shielding attenuation of coaxial connector, the test principle of shielding attenuation of coaxial connector is expounded, and the discrete frequencies method and the sweeping frequency method stipulated by standard MIL-PRF39012E and IEC62153-4-7 are compared and analyzed with self-developed test device. Based on the detailed analysis of the test results, the improvement suggestions for the shielding attenuation test method of the coaxial connector of the triaxial method are put forward.
