Electrical characteristics of the sample can be analyzed through impedance measurement analysis. This device is designed to increase user convenience by automatically measuring multiple samples in sequence and to acquire reliable data while measuring multiple samples in a short period of time. This device can analyze the resistance elements constituting the sample through C-F measurement while sweeping the frequency at a fixed bias voltage, or measure charge injection and mobility through C-V measurement while sweeping the bias voltage at a fixed frequency. In addition, by adding ThermoStation as an option, users can designate independent temperature conditions and cycles for each sample to analyze characteristics under various temperature conditions.
