SYSTEM, METHOD AND APPARATUS FOR MONITORING CHARACTERISTICS OF RF POWER

摘要

A system and method for monitoring RF power is described. In one embodiment the system samples RP power that is generated by an RP generator to obtain RF signals that include information indicative of electrical characteristics at a plurality of particular frequencies that fall within a frequency range. The RF signals are digitized to obtain a stream of digital RF signals that include information indicative of electrical characteristics at the plurality of particular frequencies, and the information indicative of electrical characteristics is successively transformed, for each of the plurality of particular frequencies, from a time domain into a frequency domain.
