For automation tunnel spectroscopy experiment provision the not expensive modern information-measuring system is designed. Due to the realization just current scanning it became possible to simplify the hardware component of system and to achieve full automation of voltage-ampere characteristic measurement as well. The features of hardware and possibilities of the software of system are described. The work is carried out within the framework of the Program of scientific instrument making of NAS of Ukraine, grant П2/09-40.
