Testing of Screening Effectiveness - of CATV Cables & TV Receiver Leads

摘要

Cables for cabled distribution systems and satellite service (CATV cables) are standardized in the IEC 61196 series. TV receiver leads are described in the IEC 60966 series. Besides electrical and mechanical characteristics, these standards specify the screening classes. For trouble-free TV reception and against unwanted radiation from cabled distribution systems, at least the screening class A is required. Regarding possible 4G/LTE problems, the screening class A+ is recommended (see Table 1).
