A normal metal - superconductor hybrid single-electron trap with tunablebarrier is utilized as a tool for spectrum analysis at the extremely low signallevels, using only well filtered cryogenic microwave background as a photonsource in the frequency range from about 50 to 210 GHz. We probe millimeterwave propagation in two superconducting systems: a Josephson junction arrayaround its plasma frequency, and a superconducting titanium film in the limitwhen the photon energies are larger than the superconducting energy gap. Thisregime is relevant for improving the performance of cryogenic quantum devicesbut is hard to access with conventional techniques. We show that relativelysimple models can be used to describe the essential properties of the studiedcomponents.
