"This part of IEC 60728: ? applies to the radiation characteristics and immunity to electromagnetic disturbance of EM-active equipment (active and passive equipment) for the reception@ processing and distribution of television@ sound and interactive multimedia signals as dealt with in the following parts of IEC 60728 series: ?C IEC 60728-3@ Active wideband equipment for cable networks; ?C IEC 60728-4@ Passive wideband equipment for coaxial cable networks; ?C IEC 60728-5@ Headend equipment; ?C IEC 60728-6@ Optical equipment; ? covers the following frequency ranges: disturbance voltage injected into the mains 150 kHz to 30 MHz; radiation from active equipment 5 MHz to 25 GHz; immunity of active equipment 150 kHz to 25 GHz 1); screening effectiveness of passive equipment 5 MHz to 3@5 GHz (25 GHz) 2); ? specifies requirements for maximum allowed radiation@ minimum immunity and minimum screening effectiveness; ? describes test methods for conformance testing. No measurement needs to be performed at frequencies where no requirement is specified. Due to the fact that cable networks@ the former cabled distribution systems for television and sound signals@ are more and more used for interactive services@ these networks also incorporate equipment that carries@ besides the cable network equipment ports@ also one or more telecom signal port(s). This equipment is called ""multimedia network equipment"". The EMC behaviour of cable network equipment@ telecommunication network equipment and multimedia network equipment can be described by the port structure given in Table 1:"
