Abstract
A probe for use in electrical circuit test equipment, in which a contact element is longitudinally slidable in an insulator sleeve which also contains an R-C attenuator circuit connected electrically to the contact element by an electrically conductive elastomeric material. A high impedance cable is connected electrically to the other end of the RC attenuator circuit by another piece of conductive elastomeric material. The cable connects the attenuator to another R-C circuit which, together with the attenuator, forms a voltage divider, and the attenuated signal controls an amplifier which provides a signal through a low impedance cable to a test equipment.
