Metallic communication cable test methods-Electromagnetic compatibility (EMC). Transfer impedance and screening attenuation of feed-throughs and electromagnetic gaskets. Double coaxial test method
金属通信电缆试验方法
This part of IEC 62153 details a coaxial method suitable for determining the transfer impedance and/or screening attenuation of feed-throughs and electromagnetic gaskets.
The shielded screening attenuation test set-up according to IEC 62153-4-4 (triaxial method) has been modified to take into account the particularities of feed-throughs and gaskets.
A wide dynamic and frequency range can be applied to test even super screened feed-throughs and gaskets with normal instrumentation from low frequencies up to the limit of defined transversal waves in the coaxial circuits at approximately 4 GHz.Incorporates the following:BS IEC 62153-4-10:2015
