Methodologies and systems are described herein whereby performance parameters of a power converter may be tested. In one or more embodiments, a system for testing the performance parameters comprises a multi-channel monitoring device including a first channel for monitoring a switch voltage of a power converter and a second channel for concurrently monitoring an output voltage of the power converter. The system further comprises a set of one or more processors for generating, as a function of the switch voltage and the output voltage, and displaying an inductor current waveform approximating current through an inductor of the power converter. Additionally or alternatively, other waveforms such as output current waveforms and inductor voltage waveforms, may be generated during testing of the power converter. An arbitrary wave generator may inject different signals during testing of the power converter.
