Metallic communication cable test methods – Part 4-4: Electromagnetic compatibility (EMC) – Shielded screening attenuation@ test method for measuring of the screening attenuation as up to and above 3 GHz (Edition 1.0)
This part of IEC 62153 determines the screening attenuation as of metallic communication cable screens. Due to the concentric outer tube@ measurements are independent of irregularities on the circumference and outer electromagnetic field. A wide dynamic and frequency range can be applied to test even super-screened cables with normal instrumentation from low frequencies up to the limit of defined transversal waves in the outer circuit at approximately 4 GHz.
