Pertains to the radiation characteristics and immunity to electromagnetic disturbance of cable networks for television signals, sound signals and interactive services and covers the frequency range 0,15 MHz to 3,5 GHz.

This part of IEC 60728 applies to the radiation characteristics and immunity to electromagnetic disturbance of cable networks for television signals, sound signals and interactive services and covers the frequency range 0,15 MHz to 3,5 GHz.

NOTE 1 Measurements below 30 MHz are not generally considered useful in the context of cable networks and are difficult to perform in practice.

This document specifies methods of measurement and EMC performance requirements under operating conditions (in situ) to ensure the ongoing EMC integrity of cable networks.

Cable networks beyond the system outlets (e.g. the receiver lead, in simplest terms) that begin at the system outlet and end at the input to the subscriber\'s terminal equipment are not covered by this document. Requirements for the electromagnetic compatibility of receiver leads are specified in IEC 60966-2-4, IEC 60966-2-5 and IEC 60966-2-6.

Cable networks and a wide range of radio services have to coexist. These include, for example, the emergency services, safety of life, broadcasting, aeronautical, radio navigation services and also land, mobile, amateur and cellular radio services. Frequency ranges of typical safety of life services are listed in Annex B. Additional protection for certain services may be required by national regulations. Annex A gives information on legal requirements in certain countries.
