Abstract
A spectrum analyser that includes means ( ) for converting, at each of a series of frequency settings, a received radio frequency signal into an intermediate frequency signal, each intermediate frequency signal being derivable from more than one nominal received radio frequency signal. The spectrum analyser carries out a frequency analysis ( ) of each intermediate frequency signal to produce a power spectrum thereof and constructs a composite received radio frequency signal power spectrum corresponding to each intermediate frequency signal power spectrum. The composite radio frequency signal power spectrums are then operated on by the spectrum analyser to provide the actual power spectrum of the received radio frequency signal.
