ABSTRACT:
A floating driver circuit. A power supply is connected through a signal source to an amplifier's input terminal. The power supply is also connected to a pair of power supply terminals of the amplifier, via at least one resistor for each power supply terminal, so that direct current flows from the power supply into the power supply terminals. Further, at least one capacitor is connected to each power supply terminal. A cable, preferably coaxial, has first and second conductors. The first conductor is connected to a signal output terminal of the amplifier. The second conductor is connected to the power supply terminals through the capacitors. A pair of these circuits is combined at opposite ends of an electrical component to enable measurement of the impedances thereof.
