  • Publication number: 20070159195
    Abstract: A differential measurement probe has a ground clip system for electrically coupling outer shielding conductors of differential probing tips together. In one embodiment, the probing tips independently move vertically relative to each other with the ground clip system secured to each of the outer shielding conductors of the probing tips. In a further embodiment, the probing tips move both vertically and horizontally and the ground clip system has a spring wire member that is secured to the probe. The spring wire member is formed with various sections having various angles to each other that allows one section to slidably engage one of the outer shielding conductors on one of the probing tips and another section to slidably engage the outer shielding conductor of the other probing tip.

  • Publication number: 20060267604
    Abstract: A differential measurement probe has spring loaded, double cushioned probe assemblies and a pressure sensors disposed in a housing. The pressure sensors forms an electrical switch having an electrical AND function for passing an activation signal to a EOS/ESD protection control module in response to axial movement of the housing relative to the probe assemblies. First compressive elements produces first pre-loaded compressive forces and increasing compressive forces on the probe assemblies and second compressive elements produces second pre-loaded compressive forces and increasing compressive forces on the probe assemblies subsequent to the first increasing compressive forces on the probe assemblies. An adjustment member allows variable spacing of the differential probing tips.

  • Publication number: 20060267602
    Abstract: A signal acquisition probe has a double cushioned spring loaded probing tip assembly disposed in a housing. A first compressive element produces a first pre-loaded compressive force and an increasing compressive force on the probing tip assembly and a second compressive element produces a second pre-loaded compressive force and an increasing compressive force on the probing tip assembly subsequent to the first increasing compressive force. First and second double cushioned spring loaded probing tip assemblies may be disposed in a housing to produce a differential signal acquisition probe.

  • Publication number: 20050231307
    Abstract: A switching apparatus has a conductive housing forming a chamber. The housing has an aperture enabling communication between the chamber and a housing exterior. A rod extends through the aperture, and has a first end within the chamber, and an opposed second end outside the chamber. The rod reciprocates over a range of motion between a first position in which a limited portion of the rod extends into the chamber, and a second position in which a greater portion of the rod extends into the chamber. The rod has a electrically insulative portion electrically isolating the first end from the second end, and has a conductive surface contacting the housing. A pair of electrical contacts are located in the chamber, and a shorting bar connected to the first end of the rod operates to bridge the contacts when the rod is in a selected position.
