Abstract: An analyzer sensor for detecting signal waveforms on a pair of conductors. The apparatus includes capacitive couplers connected to termination impedance and adapted for placement adjacent to the conductors to capacitively couple the signals of the conductors to the associated termination impedance. The invention further includes a first and second buffer amplifier responsive, respectively, to the signals at the termination impedances, for providing at a first and second output thereof, respectively, an amplified difference of the signals. Furthermore, the invention includes a utility module having a battery source connected to the buffer amplifiers by a line for providing power to the buffer amplifiers at a location distant from the buffer amplifiers.
