Abstract: PROBLEM TO BE SOLVED: To provide an analyzer sensor capable of providing samples of signal waveforms passing a conductor for signal analyzing. SOLUTION: There is provided the analyzing sensor which is an apparatus for detecting the signal waveforms of a pair of conductors. This apparatus has capacitive couplers which are connected to termination impedance and is to be placed adjacent to the conductors to capacitively couple the signals of the conductors to the related termination impedance. The apparatus also has a first and a second buffer amplifiers for respectively providing an amplified difference of the signals to first and second outputs so as to response respectively to the signals at the termination impedance. The apparatus further has a utility module provided with a battery power source which is connected to the buffer amplifiers by a line and supplies power to the buffer amplifiers at a location distant from the buffer amplifiers.
