Abstract
Probes for testing electrical circuits having decoupled electrical and mechanical design are provided. For example, a mechanically resilient core can be surrounded by an electrically conductive shell. In this way, electrical parameters of the probes are determined by the shells and mechanical parameters of the probes are determined by the cores. An important application of this approach is to provide impedance matched transmission line probes.
