	Most spectrum analyzers are really scanning (sometimes called
panoramic) receivers and as such don't really measure measure spectra.
Doesn't mean they aren't useful of course.  There are some instruments
which actually convert blocks of waveform to digital form and do a real
spectrum analysis by a FFT algorithm, but they are in the minority.
