Abstract:

The Goetech analog spectrum analyzer and the manner in which it operates are discussed in general terms. The fundamentals of Fourier analysis, as they relate to the operation of the system, are outlined. Sufficient detail is provided to give a working comprehension of the analyzer and the spectrograms it produces. The results of various tests on the electronic characteristics of the system are presented. These include frequency and phase response, noise level, and linearity. An assessment is made of the overall accuracy of the spectrograms. The spectra of simple repetitive waveshapes and transients are discussed and examples given. Author
