IEC 60728-2:2018(E) 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 IEC 60728-3, IEC 60728-4, IEC 60728-5 and IEC 60728-6. This document 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; - screening effectiveness of passive equipment: 5 MHz to 3,5 GHz. This document specifies requirements for maximum allowed radiation, minimum immunity and minimum screening effectiveness and describes test methods for conformance testing. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Frequency extensions: a.1) The upper frequency limit of conventional cable network equipment was extended from 862 MHz to 1 000 MHz due to market demands. a.2) The first intermediate frequency range (1st IF range) for satellite signal transmission was extended to cover now frequencies from 950 MHz up to 3 500 MHz. a.3) The methods of measurement and the EMC requirements in the overlapping frequency range from 950 MHz to 1 000 MHz were allocated in relation to the upper frequency limit, 1 000 MHz, and the lower frequency limit, 950 MHz, of the relevant equipment under test. b) New EMC environment in the 800 MHz band: b.1) The European Commission has requested CENELEC and ETSI to draft immunity requirements for equipment, to protect against disturbance from the new wireless service in the 790 MHz to 862 MHz band. b.2) A CENELEC/ETSI Joint Working Group "Digital Divide ...
