Composite Triple Beat Measurements (1975)

By Bert Arnold, RCA Community Television Systems

This paper presents a set of curves which show the relative readings between a power meter signal level meter and spectrum analyzer, when measuring the composite (summation) triple beat on a particular channel. The curves allow the CATV operator to obtain a correct measurement (RMS) of .composite triple beat for system performance when using common instruments such as the spectrum analyzer or signal level meter.

A plot of a computer run made at RCA is also given showing the total equivalent triple beats on the worst case channel versus the number of channels.
