BASICS OF THE SPECTRUM ANALYZER
web.ece.ucsb.edufrequency, say fI, and we shall scan the signal spectrum across this filter by multiplying x(t) by a sinusoid of varying frequency f0. See Figure 1. The filter is a narrow bandpass filter at a fixed center frequency, fI, (called the intermediate frequency); in a spectrum analyzer, its bandwidth is selected by the user.
