Fiber optic oscilloscope probe

Summary form only given, as follows. In the recent development of high voltage solid state pulsed power systems the ability to analyze low voltage signals in a high voltage environment has been a problem. The amplitude of any ground bounce from the high voltage pulse can make the interpretation of low voltage diagnostic signals difficult with industry standard probes. The paper explains the development of a fiber optic voltage probe for the oscilloscope. Included are explanations of the probes design, function, limitations, and comparisons with standard probes in a high voltage pulsed power environment.
