Claim Text:
1. An electrosurgical generator comprising: a primary signal generator including a first oscillator configured to generate a primary signal having a first frequency; a test signal generator including a second oscillator configured to generate a test signal to detect a location of an abnormality in the electrosurgical generator, wherein the test signal has a second frequency different from the first frequency; a radio frequency (RF) output circuit electrically coupled to the primary signal generator and the test signal generator, the RF output circuit configured to receive the primary signal and the test signal, respectively, therefrom, wherein the RF output circuit is electrically coupled to a load to supply the primary signal and the test signal to the load; and an abnormality detection circuit electrically coupled to the RF output circuit to detect an abnormality within the RF output circuit based on an impulse response of the RF output circuit in response to the test signal, wherein the abnormality detection circuit is configured to determine a location of the abnormality within the RF output circuit based on the impulse response of the RF output circuit in response to the test signal.
