Spectrum Analyzer Fundamentals: Theory and Operation of Modern Spectrum Analyzers
This primer examines the theory of state-of-the-art spectrum analysis and describes how modern spectrum analyzers are designed and how they function. From the basics of FFT Analyzers to frequency selection and intermediate frequency signal processing to signal generators and their use, this white paper shows how the effects on the spectrum caused by the non-linearity of real devices under test are derived mathematically.
