Claim 12:
13. A radio frequency (RF) generator comprising:
a first RF generator including a first power source generating a first RF signal applied to a load; and
a second RF generator including:
a second power source generating a second RF signal applied to the load; and
a power controller coupled to the second power source, the power controller configured to respond to a trigger signal and to generate a RF control signal and an actuator control signal, wherein the RF control signal adjusts an electrical parameter of the second RF signal and wherein the actuator control signal adjusts an actuator of a match network associated with the second RF signal,
wherein the trigger signal indicates a first portion of a negative voltage segment of the first RF signal, and

wherein the electrical parameter includes at least one of a power of the second RF signal or a frequency of the second RF signal.
