The shielding effectiveness of data cables are tested under complex electromagnetic compatibility conditions in the test room for EMC. For balanced twisted-pair cables, the coupling attenuation (IEC 62153-4-9) performance and transfer impedance (IEC 62153-4-3) performance are tested. Meanwhile, the shielding attenuation (IEC 62153 -4-4) performance of the twisted-pair or coaxial cables can also be tested.
The test room for EMC will continue to develop new testing technologies and methods based on an in-depth understanding of IEC 62153 series standards, and continue to expand its testing capabilities.
