Claim One:
1. In a plasma processing system, a method of creating a simplified equivalent circuit model of a plasma processing system, including an electrical measuring device, a lower electrode, an upper electrode, and a signal generator device comprising: creating a simplified equivalent circuit equation, including a set of variables, of said plasma processing system, wherein said electrical measuring device comprises a first subset of variables, said lower electrode comprises a second subset of variables, said upper electrode comprises a third subset of variables, and said signal generator device comprises a forth subset of variables; generating a first set of signals, each of said first set of signals being generated at a different frequency, wherein said signal generator device is coupled to said electrical measuring device, said lower electrode, and said upper electrode; measuring said first set of signals with said electrical measuring device, wherein at least one measured signal is generated for each of said set of variables; creating a simplified equivalent circuit model from said first set of signals.
