scope:

This standard is applicable to any cabled distribution system (including individual receiving systems) having coaxial cable outputs in order to assess the performance of those systems and their performance limits. All requirements refer to the performance limits which shall be obtained between the input(s) to the headend or headends and any system outlet when terminated in a resistance equal to the nominal load impedance of the system, unless otherwise specified, Where system outlets are not used, the above applies at the subscriber's end of the subscriber' s feeder.
