FIELD: radio engineering, communication.
SUBSTANCE: two-terminal device is subjected to a test voltage video pulse; current through the two-terminal device ij and voltage across the two-terminal device uj at discrete moments in time tj is measured; the time derivative of voltage across the two-terminal device u'j at time tj is calculated; results of interpolating tabulated functions are used to obtain the relationship between current through the two-terminal device ir(u) and if(u) and voltage across the two-terminal device at the front and trailing edge of the video pulse, respectively, as well as the relationship between the time derivative of voltage across the two-terminal device u'r(u) and u'r(u) and voltage across the two-terminal device at the front and trailing edge of the video pulse, respectively, wherein the argument of the tabulated functions is the measured voltage across the two-terminal device uj at the front of the video pulse for functions ir(u) and u'r(u) and the measured voltage across the two-terminal device uj at the trailing edge of the video pulse for functions uf(u) and u'f(u), and values of the tabulated functions are the measured values of current through the two-terminal device ij at the front of the video pulse for the function ir(u), the measured values of current through the two-terminal device ij at the trailing edge of the video pulse for the function ir(u), the calculated values of the time derivative of voltage across the two-terminal device u'r(u) at the front of the video pulse for the function u'r(u) and the calculated values of the time derivative of voltage across the two-terminal device u'j at the trailing edge of the video pulse for the function u'r(u), the voltage-current characteristic iIV(u) is calculated using the formula 
EFFECT: method which enables to simultaneously measure voltage-current and voltage-capacitance characteristics of a two-terminal device using measurements of current through the two-terminal device and voltage across the two-terminal device at discrete moments in time under continuing charge-discharge conditions of the capacitor of the two-terminal device.
