FIELD: electric measurement technology, development of methods and means for nondestructive testing. SUBSTANCE: technical objective lies in elimination of disadvantages of known methods and in possibility of determination of value of level of nonlinearity of volt-ampere characteristic of passive non-polar inertia-free two- terminal network with the aid of power function with real exponent of power of current. Method includes transmission of periodic sequence of pairs of rectangular video pulses of current through passive non-polar inertia-free two-terminal network Value of constant component of current of periodic sequence of pairs of video pulses is negligible. EFFECT: improved efficiency of method. 2 cl, 1 tbl
