Abstract: An apparatus for determining a response of a device under test to an electrical pulse generated by a pulse generator. The apparatus can include a conductor for coupling the electrical pulse generator to the device under test and at least two sensing probes connected to the conductor. Each of the at least two sensing probes can be positioned at one of at least two measurement points and can be 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. A determination device can be 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 nd the transit times of the electrical pulse between these different measurement points.

Abstract: Method for determining relevant circuit parts in a circuit in the event of loading with a temporally variable signal comprises providing a computer-implemented model of the circuit, in which the circuit components are represented at least partly by equivalent DC signal models, the parameters of which take account of at least one parameter of the temporally variable signal, carrying out a DC signal analysis for the circuit on the basis of the model provided, and taking account of a DC signal which is present at at least two connections for coupling in the temporally variable signal and is dependent on at least one of the parameters of the temporally variable signal.

Abstract: Method for determining relevant circuit parts in a circuit in the event of loading with a temporally variable signal, the circuit having a number of circuit components which are connected up to one another and are in each case connected up by means of connections between at least two circuit nodes, at least one relevance criterion in each case being assigned to at least some of the circuit parts, and the circuit having at least one first and one second connection for coupling in the temporally variable signal, the method comprising the following method steps of: providing a computer-implemented model of the circuit, in which the circuit components are represented at least partly by equivalent DC signal models, the parameters of which take account of at least one of the following parameters of the temporally variable signal: gradient of a rising edge, duration of a pulsed signal component, gradient of a falling edge, carrying out a DC signal analysis for the circuit on the basis of the model provided, taking a
