摘要： An electrosurgical generator includes an RF output stage, a current sensor, a voltage sensor, first and second log amplifiers, and a controller. The RF output stage is configured to supply electrosurgical energy to tissue. The current sensor is configured to sense a current of the electrosurgical energy and generate a current signal corresponding to the current of the electrosurgical energy. The first log amplifier is configured to amplify and compress the current signal. The voltage sensor is configured to sense a voltage of the electrosurgical energy and generate a voltage signal in response thereto. The second log amplifier is configured to amplify and compress the voltage signal. The controller is configured to receive the amplified voltage signal and the amplified current signal and operatively control the generation of the electrosurgical energy as a function of the amplified voltage signal and the amplified current signal.

摘要： A microwave ablation system includes a generator including a first energy source, a second energy source and a diplexer, the diplexer multiplexes a first energy from the first energy source and a second energy from the second energy source. The system also includes a cable including a center conductor and an outer sheath where the multiplexed energy is transmitted through the center conductor. In addition an antenna is provided that is operable to receive the multiplexed energy from the center conductor and to deliver the multiplexed energy to a region of tissue. The outer sheath acts as a return path of the second energy to the second energy source. A sensor is also provided that measures at least one parameter of the second energy generated by the second energy source and the second energy returned from the region of tissue.

摘要： A digital measurement system includes an oscillator, a mixer, and a controller coupled to each other. The oscillator provides a reference signal having a second frequency. The mixer generates a down-converted signal based on the output signal and the reference signal. The controller then determines a characteristic of the output signal (e.g., frequency or phase) based on the down-converted signal. An analog measurement system includes a filter having a center frequency, a rectifier, and a controller. The filter filters the output signal and the rectifier rectifies the filtered signal. The controller samples the rectified signal and determines a characteristic of the output signal based on the level of the rectified signal. The reference signal controller may adjust a characteristic of the output signal based on the determined frequency and/or phase of the output signal.
