EN 50083-8 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. It should be noted that measurements below 30 MHz are not generally considered useful in the context of cable networks and are difficult to perform in practice. Application of the harmonized standard EN 50529-2 provides presumption of conformance to the EMC Directive. Therefore, to fulfil the requirements of EN 50529-2, it is necessary to use cable network equipment that satisfies the requirements of EN 50083-2 regarding limits of radiation and of immunity to external fields. This European Standard 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) which begin at the system outlet and end at the input to the subscriber's terminal equipment are not covered by the standard EN 50083-8. Requirements for the electromagnetic compatibility of receiver leads are laid down in EN 60966-2-4, EN 60966-2-5 and EN 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.
