An experimental setup for quality assurance of the BM@N experiment tracking modules based on pulsed diode lasers is described. The main idea of the setup is to simulate an ionizing particle traversing a silicon sensor of the module. The tracking modules are based on silicon microstrip sensors and readout electronics STS-XYTER ASICs. Diode lasers with wavelengths of 635 and 1064 nm are used in the setup. The lasers are powered by a pulse oscillator which can generate rectangular pulses with high frequency. Laser radiation is transmitted through a single-mode optical fiber and an attenuator to a focuser and then is focused on a tracking module sensor. After that, the module is moved along with a positioning table in order to measure signals from all strips and readout channels.
