ABSTRACT:
A method for measuring a resistance and a capacitance of an electronic component utilizes electron beam measuring technology to impress a current I.sub.A by means of a pulsed electron beam on the component. A potential curve U(t) which arises during the pulse on the electronic component as a result of the impressed current is utilized together with the known current to determine the resistance R and the capacitance C by means of an appropriate selection of two measuring points U(t.sub.1) and U(t.sub.2) on the potential curve.
