An apparatus for conditioning an output waveform delivered from a testing device produces an output voltage that is the sum of a control voltage and an input voltage. To that end, the apparatus includes an input for receiving the input voltage, and an output capable of producing the output voltage. The output is coupled with the testing device. The apparatus further includes a voltage element coupled between the input and the output, and a switching element to alternatively charge and discharge the voltage element. The switching element controls the voltage element to change the control voltage between a first voltage and a second voltage. Consequently, the output voltage is the sum of the control voltage and the input voltage.
