Abstract. The setup for research the phenomena of giant magnetoimpedance in thin films and microwires was developed. The proceses of measuring, processing and imaging of the results are automated.  The ranges and steps of the magnetic field, frequency and amplitude of current through the sample, a number of other parameters are specify in the experiment. The setup allows to research the magnetoimpedance material properties in the frequency range up to 1 GHz in the temperature range from -70 ° C to 180 ° C.
