1. An apparatus for determining a response of a device under test to an electrical pulse generated by a pulse generator, comprising:
a conductor for coupling the electrical pulse generator to the device under test, wherein the conductor has a predetermined electrical impedance and a predetermined pulse propagation velocity;
at least two sensing probes connected to the conductor, wherein each of the at least two sensing probes is positioned at one of at least two measurement points on the conductor and is configured to generate a signal in direct proportion to a current flowing in or a voltage applied to the conductor at the corresponding measurement point; and
a determination device configured to determine the response of the device under test to the electrical pulse based on the signals generated by the at least two sensing probes;
and wherein at least two of the at least two sensing probes are positioned at different measurement points of the at least two measurement points, a distance between two of these different measurement points on the conductor is respectively defined in such a way that a transit time of the electrical pulse between these two different measurement points is determinable by the determination device and the determine device is configured to determine the response of the device under test based on the signals generated by the at least two sensing probes and the transit time of the electrical pulse between these different measurement points.
