Abstract
Abstract A connector evaluating adapter composed of ground electrodes of connector terminal ends electrically interconnected via a metal housing. Through capacitors are used between opposed signal electrodes of the connector terminal ends. External electrodes of the through capacitors are electrically connected to a metal plate, and the metal plate is connected via conductive members to the ground electrodes, such that the metal plate corresponds to an electrical midpoint between the ground electrodes. When high-frequency noise flows into the ground electrodes, the ground electrodes and the metal plate are equipotential. After the through capacitors eliminate superimposed noise from electrical signals, the metal plate again becomes almost equipotential to the ground electrodes. Since both ends of the metal housing are equipotential, no current flows through the metal housing, thus generating no noise.
