Omfang

This standard is applicable to any cabled distribution system (including individual receiving systems) having a coaxial cable output and primarily intended for television and sound signals operating between about 30 MHz and 1750 MHz. This standard lays down the basic methods of measurement of the operational characteristics of cabled distribution 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 susbcriber's end of the susbcriber's feeder. NOTE 1: Methods of measurement described in this standard are considered as basic. However, any equivalent method that ensures at least the same accuracy may be used. NOTE 2: If the system operator wishes to subdivide the system into a number of parts, the accumulation of degradations should not exceed the figures given below. NOTE 3: An extension of the frequency range to that from 5 MHz to 2050 MHz(3000 MHz) will be considered for future work
