Noise Figure Measurements On Distribution Systems (1984)
By Donald E. Groff, General Instrument Jerrold Division
A technique for measuring the noise figure of a CATV distribution system is discussed, as an alternative to conventional methods of determining carrier to noise ratio. The advantages and disadvantages of both types of measurement are discussed. Suitable instrumentation for noise figure measurement is considered, as well as calibration techniques. Some possible sources of error are identified and analyzed.
