PROBLEM TO BE SOLVED: To dispense with a terminal element for enhancing measuring precision, in an instrument for measuring a characteristic of an FET by imparting a pulse to a gate. SOLUTION: This instrument of generating the pulse imparted to the gate G of the FET 500, and for measuring the characteristic of the FET 500 by measuring a voltage dependent on a drain current flowing in the FET 500 in response to the pulse, is provided with a pulse generator 210 for generating the pulse, a directional element 230 arranged in a post stage of the pulse generator 210, and a voltage measuring means 250 for measuring the voltage.
