    Abstract - (Show below) - (Hide below)

    Applicable to any cable network having a coaxial cable output and primarily intended for television and sound signals operating between about 30 MHz to 2 150 MHz. Describes basic methods for measuring the operational characteristics of cable networks having coaxial cable outputs in order to assess the performance of those networks and their performance limits.
