Abstract
A testing apparatus that comprises an electrical device. A first circuit is in electrical communication with the electrical device. The first circuit including an amplifier. First and second couplers are electrically connected to the first circuit and arranged in series with the amplifier. The amplifier is positioned between the first and second couplers. A second circuit has a first end in electrical communication with the first coupler and a second end in electrical communication with the second coupler. The total gain of the first coupler, the second coupler, the portion of the first circuit between the first and second couplers, and the second circuit is approximately zero.
