scope:

This part of IEC 60728 lays down the measuring methods, performance requirements and da ta publication requirements for active wideband equipment of cable networks for television signals, sound signals and interactive services. This standard • applies to all amplifiers used in cable networks; • covers the frequency range 5 MHz to 3 000 MHz; NOTE - The upper limit of 3 000 MHz is an example, but not a strict value. The frequency range, or ranges, over which the equipment is specified, should be published. • applies to one-way and two-way equipment; • lays down the basic methods of measurement of the operational characteristics of the ac tive equipment in order to assess the performance of this equipment; • identifies the performance specifications to be published by the manufacturers; • states the minimum performance requirements of certain parameters.
