Abstract
A system has a first RF generator and a second RF generator. The first RF generator controls the frequency of the second RF generator. The first RF generator includes a power source, a sensor, and a sensor signal processing unit. The sensor signal processing unit is coupled to the power source and to the sensor. The sensor signal processing unit scales the frequency of the first RF generator to control the frequency of the second RF generator.
