<P>PROBLEM TO BE SOLVED: To provide a heterodyne beat probe scanning probe tunnel microscope capable of easily and unfailingly detecting a weak RF signal, and a method of specifying a heterodyne beat signal by the scanning probe tunnel microscope. Ž<P>SOLUTION: The scanning probe tunnel microscope includes a scanning tunnel microscope analyzing section for superimposing a given known externally superimposed reference high-frequency signal or externally superimposed reference electromagnetic signal on an unknown high-frequency signal or electromagnetic signal and causing quantum interference, wherein the externally superimposed reference high-frequency signal or externally superimposed reference electromagnetic signal is gradually approximated to the unknown high-frequency signal or the electromagnetic signal and is subjected to frequency sweeping to cause quantum interference, a tunnel current modulated by generating a heterodyne beat signal is generated from the quantum interference, and the unknown high-frequency signal or electromagnetic signal is detected.
