Abstract
A signal analysis apparatus includes a frequency conversion unitthat includes a first local oscillatorwhich outputs a first local oscillation signal Sof a frequency f, a first mixerwhich generates a first spurious signal of a frequency f, a first BPFof a passed center frequency f, a second local oscillatorwhich outputs a second local oscillation signal Sof a frequency f, and a second BPFof a passed bandwidth W, and that performs frequency conversion of a measured signal Sof a frequency f(center frequency fc), in which the frequency fand the frequency fare shifted using a frequency shift amount Δf that does not establish a relationship of −W/2≤|f−f±f−Δf|−f≤+W/2.
