Full Description

IEC60728-12:2017(E) 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 0,15MHz to 3,5GHz.This second edition cancels and replaces the first edition published in 2001. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:
a) IEC60728-12 with its methods of measurement and EMC performance requirements is explicitly dedicated to under operating conditions (in situ) to ensure the ongoing EMC integrity of cable networks.
b) The first intermediate frequency range (1st IF range) for satellite signal transmission was extended to cover now frequencies from 950MHz up to 3 500MHz.
c) The method of measurement and the requirements for in-band immunity were extended taking into account the new EMC environment due to the allocation of broadband wireless services in the frequency band 694MHz to 862MHz. As a consequence, the limits of in-band immunity were specified for analogue and additionally for digital signals in this frequency range.
d) The substitution method of measurement (power method) was deleted.
e) EMC measurements below 30MHz were deleted.
f) New Annex D Measurements at other distances than the standard distance of 3m.
g) New Annex E GPS based leakage detection system for cable networks.
