<p>An active voltage probe receiving a DC power voltage via an outer conductor of a coaxial cable is disclosed. The probe includes a differential amplifier with inputs connected to input and reference terminals via DC paths and a follower amplifier with an input connected to the input terminal via an AC path. Outputs currents from the differential and follower amplifiers are applied to an inner conductor of the coaxial cable.</p> |
