In this paper. a theoretical calculation of a radio-photon mixer is performed using spectral analysis of signals and the results of an experimental study of the spectral composition of optical signals in a radio-photon mixer. An experimental setup consisting of a source of optical radiation. two Mach - Zehnder modulators. https://www.jmannino.com/mega-pick-Royal-Nomadic-5413-Rug-Ivory-Black-limited-super/
