Abstract
A device for generating RF power for an electrosurgical instrument is provided that includes a controller programmed to generate an electrical signal having an oscillating waveform and to modulate the oscillating waveform between a plurality of ON and OFF states to create discrete packets of the oscillating waveform in the plurality of the ON states. The device further has an amplifier in communication with the electrical waveform that amplifies the waveform to create an output signal and an electrosurgical connector configured to receive an electrosurgical instrument and to pass the electrical signal to the electrosurgical instrument.
