This module is an adjustable secondary switch-mode power supply unit 0–30 V for supplying the power stage of the RF generator and adjusting the amplitude of the output signal. The output voltage can either be controlled manually (via a 10-turn potentiometer) or via an external control voltage (a 10 V port).
