Abstract
A generator is configured to output two or more waveforms at different frequencies. In particular, the generator is configured to provide an ultrasonic waveform, which may be suitable for driving a transducer of an ultrasonic surgical instrument, and electrosurgical radiofrequency energy, which may be suitable for electrosurgical instruments.

1-20. (canceled)
A surgical generator, comprising:
- a power supply;
- an amplifier coupled to the power supply and configured to output a first waveform and a second waveform;
- a first controller configured to provide a first control signal to the amplifier to generate the first waveform;
- a second controller configured to provide a second control signal to the amplifier to generate the second waveform;
- and
- a switch configured to pass through one of the first control signal or the second control signal to at least one of the power supply or the amplifier.
