A measurement apparatus for FET characteristics comprises a divider connected to a pulse generator for dividing pulses from the pulse generator into first and second pulses; a first SMU; a first switch for selecting pulses from the divider or voltage from the first SMU; a terminal resistor for applying signals from the first switch and supplying the signals to the first terminal of the device under test; a second and a third SMU; a bias-T connected to the third SMU; a second switch for selecting to connect the second terminal of the device under test to the second SMU or to connect the second terminal to signals of the bias-T obtained by multiplexing the voltage from the third SMU; and voltage measurement unit connected to the divider and the bias-T.
