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 &#x394;f that does not establish a relationship of &#x2212;W/2&#x2264;|f&#x2212;f&#xb1;f&#x2212;&#x394;f|&#x2212;f&#x2264;+W/2.
