The Spectrum Analyzer (1966)
By Allen Ross, Nelson Ross Electronics
The spectrum analyzer is an instrument that is probably unheard of in this particular industry. It is a useful instrument which has been around for a long time, originating with the esoteric military requirements. The state of the art in spectrum analysis has gradually improved to the point where it is possible to build spectrum analyzers which cover very wide frequency bands. There are now a few people making analyzers which permit observation of the entire CATV spectrum -- channels 2 to 13 (including all the FM in between) in one sweep. These analyzers will permit very useful advances in the systems for testing CATV transmission.
