Abstract
A signal analysis apparatus includes a first frequency conversion unitthat generates an intermediate frequency signal Sand a second spurious signal Sfrom a measured signal Sof a frequency f(center frequency f), and a second frequency conversion unitthat converts the intermediate frequency signal Sand the second spurious signal Sinto an intermediate frequency signal S' of a frequency f′ and a second spurious signal S′ of a frequency f′ by performing frequency shift of the intermediate frequency signal Sand the second spurious signal Sby a frequency shift amount Δf, in which the frequency shift amount Δf is a value that does not establish a relationship of −W/2≤f′−f′≤+W/2.
