Measuring the shielding effectiveness of coaxial cables using a reverberation chamber

The measurement of shielding effectiveness of coaxial cables is often limited by the dynamic range of the measurement system. This paper discusses the methods used to establish a dynamic range of 150 dB at 1 GHz, and 120 dB at 18 GHz, using a small reverberation chamber to measure the shielding effectiveness of coaxial cables. The chamber used had dimensions of 1.8/spl times/1.2/spl times/0.8 m.
