Abstract
The invention relates to an apparatus and method to determine contact dynamics between conductive surfaces, and more particularly to determine the dynamics of contact closure in mechanical switches and analysis of the dynamics of other mechanical systems, in general. A log amp is in electrical communication with the RF synthesizer via a transmission line. The log amp outputs a voltage converted from an envelope of an RF waveform to determine a capacitance between at least two conductive surfaces.
