A probing adapter has a support member receiving a probing tip assembly having probing arms. The probing tip assembly is mounted to the support member via a rotational joint having elastomeric member disposed in the probing arms with each of the probing arms having a pivot point disposed away from the rotational joint. Each of the probing arms supports a removable probing tip substrate having a probing tip at one end electrically coupled via an electrical signal conductor to an electrical connector at the other end. Substrate retention clips secure the removable probing tip substrates to the probing arms. A probing tip positioning member is mounted to the probing arms for varying the distance between the probing tips on the removable probing tip substrates.

A wide bandwidth attenuator input circuit for a measurement probe has a Zattenuator circuit coupled in series with a compensated RC attenuator circuit. The series attenuator elements of the Zand the compensated RC attenuator circuits are coupled via a controlled impedance transmission line to the shunt attenuator elements of the Zand the compensated RC attenuator circuits. The shunt element of the Zattenuator element terminates the transmission line in its characteristic impedance. The junction of the series and shunt attenuator elements are coupled to the input of a buffer amplifier. At low and intermediate frequencies, the compensated RC attenuator circuit attenuates an input signal while at high frequencies, the compensated RC attenuator circuit acts as a short and the Zattenuator circuits attenuates the input signal.
