SYSTEMS AND METHODS FOR TUNING A MHZ RF GENERATOR WITHIN A CYCLE OF OPERATION OF A KHZ RF GENERATOR

Abstract:

Systems and methods for tuning a megahertz radio frequency (RF) generator within a cycle of operation of a kilohertz (kHz) RF generator are described. In one of the methods, a predetermined periodic waveform is provided to a processor. The processor uses a computer-based model to determine plurality of frequency parameters for the predetermined periodic waveform. The frequency parameters are applied to the megahertz RF generator to generate an RF signal having the frequency parameters during one or more cycles of operation of the kilohertz RF generator.
