It is therefore an object of the present invention to provide an apparatus and method for calibrating voltage spike waveforms that are used to test the survivability and compatibility characteristics of electrical equipment including military and commercial off-the-shelf electrical devices. It is another object of the present invention that the aforesaid apparatus and method be relatively inexpensive to implement. Thus, the present invention is directed to, in one aspect, an apparatus for calibrating voltage spikes used in testing an electrical device, comprising an input for receiving a voltage spike, and power supply inputs for receiving power for energizing an electrical device under test. The power supply inputs comprise a high voltage input, a common input and a ground input. The apparatus further comprises a plurality of outputs comprising a high voltage output, a common output, and a ground output. The plurality of outputs are configured for connection to corresponding high voltage, common and ground inputs of the electrical device under test. The power supply common and ground inputs are connected to the common and ground outputs, respectively. The apparatus further comprises a circuit for connecting and disconnecting the power supply high voltage input to and from, respectively, the high voltage output, selecting a pair of the plurality of outputs, transforming the voltage spike into a predetermined voltage spike waveform, and applying the predetermined voltage spike waveform to the selected pair of outputs.
