Abstract

Spectrum analyzers for communication systems are traditionally modeled by a bank of narrowband filters with equally spaced frequency centers and bandwidths. This matches the structure of communication system channelized bandwidth frequency assignments that in turn influenced the design of early swept frequency spectrum analyzers. They were designed around a fixed bandwidth intermediate frequency filter through which spectral regions are probed by shifting them to the filter with a linear time-frequency swept heterodyne.
