The invention relates to a device for digitally processing signals which is integrated within a software-hardware operating system of an automatic station which measures the laser-irradiated optical components destruction threshold. According to the invention, the device for digital signal processing, DSP (12), is employed in digital signal processing, being used as an interface between the peripheral execution elements associated to the installation and a personal computer PC (13) and consists of functional blocks dedicated to the control of the peripheral units of the station: laser pulse counter, beam obturating controller, variable attenuator controller, beam collecting controller, site destruction monitor, translation table controller.
