Abstract

Systems and methods for synchronization of radio frequency (RF) generators are described. One of the methods includes receiving, by a first RF generator, a first recipe set, which includes information regarding a first plurality of pulse blocks for operating the first RF generator. The method further includes receiving, by a second RF generator, a second recipe set, which includes information regarding a second plurality of pulse blocks for operating a second RF generator. Upon receiving a digital pulsed signal, the method includes executing the first recipe set and executing the second recipe set. The method further includes outputting a first one of the pulse blocks of the first plurality based on the first recipe set in synchronization with a synchronization signal. The method includes outputting a first one of the pulse blocks of the second plurality based on the second recipe set in synchronization with the synchronization signal.
