The Common Exciter circuit enables the simultaneous operation of multiple RF power systems powering multiple plasma loads inside a common vacuum chamber. Typically, the Output of one PB3 will connect to the Input of the next (and so on). The Common Exciter circuit is used to keep all RF generator’s output frequencies synchronized helping the impedance matching process.Also note that the Model PB3 RF system has been delivered to the field with two types of common exciter circuits: The early version does require a jumper. Please install a jumper (BNC>BNC) to enable the RF output power. The newer models do not need an external jumper to enable the RF power stage. This version has been shipping since 1998. If a jumper is connected between the Input & Output, the RF output power will automatically be disabled.
