    摘要: A portable electrosurgical system (100) for treating biological tissue with microwave radiation (e.g. having a frequency between 500 MHz and 60 GHz) is disclosed. The system comprises a hand-held microwave sub-assembly (102) which generates and amplifies a microwave signal (which may be continuous or modulated) for treatment and includes a treatment antenna (116) for delivering the radiation. Diode detectors (120, 122) in the sub-assembly (102) may detect forward and reflected power levels to enable determination of net delivered power. A dynamic impedance matching system may be provided to match energy developed by amplifiers (110, 112) in the sub-assembly (102) to the biological tissue load. A tuning filter (144) and couplers (146, 148, 150, 152) for extracting magnitude and phase information from the microwave signal are thus provided in the sub-assembly.

    摘要: A system and method for displaying digital interface symbol information from at least one analog signal is provided. The digital interface symbol information includes encoded symbols as well as decoded information the encoded symbols represent. First, a set of data samples of the analog signal is captured at a frequency at least as high as the switching rate of the analog signal. The set of data samples is then converted into a serial bit stream by way of either a provided or extracted clock. The serial bit stream is searched for one or more sync symbols identified with the particular encoding scheme employed in the digital interface. Using the sync symbols, the encoded symbols in the serial bit stream are identified. At least some of the digital interface symbol information, such as the encoded symbols and the decoded information, are then correlated and displayed with a trace of the analog signal.
