Abstract: A stimulation device notably for testing radio reception devices is provided. It includes a signal generator delivering an amplitude-phase law for beam-forming purposes, transmitted in the form of a composite laser beam which illuminates a matrix of photodiodes of an emission subassembly with active modules separate from the generator, each wavelength of the beam carrying one of the signals defining the amplitude-phase law, intended for an active module. The device comprises means for measuring the orientation of the composite laser beam relative to the matrix of photodiodes of the emission subassembly and the distance traveled by the beam thereto, and correcting the phase law generated by the signal generator so as to neutralize the stray phase-shifts induced by these parameters on the signals transmitted to the emission subassembly.
