    Abstract: Shielded probe systems are disclosed herein. The shielded probe systems are configured to test a device under test (DUT) and include an enclosure that defines an enclosure volume, a translation stage with a stage surface, a substrate-supporting assembly extending from the stage surface, an electrically conductive shielding structure, an isolation structure, and a thermal shielding structure. The substrate-supporting assembly includes an electrically conductive support surface, which is configured to support a substrate that includes the DUT. The electrically conductive shielding structure defines a shielded volume. The isolation structure electrically isolates the electrically conductive shielding structure from the enclosure and from the translation stage. The thermal shielding structure extends within the enclosure volume and at least partially between the enclosure and the substrate-supporting assembly.

    Abstract: Shielded probe systems are disclosed herein. The shielded probe systems are configured to test a device under test (DUT) and include an enclosure that defines an enclosure volume, a translation stage with a stage surface, a substrate-supporting stack extending from the stage surface, an electrically conductive shielding structure, an isolation structure, and a thermal shielding structure. The substrate-supporting stack includes an electrically conductive support surface and a temperature-controlled chuck. The electrically conductive shielding structure defines a shielded volume. The isolation structure electrically isolates the electrically conductive shielding structure from the enclosure and from the translation stage. The thermal shielding structure extends within the enclosure volume and at least partially between the enclosure and the substrate-supporting stack.

    Abstract: A current measurement connector may include a first part and a second part. Each part may include a mount and a joint. The first and second part may be joined via the respective joints through a current transformer interposed between the first and second parts. The respective mounts may be configured to receive a current from a current source and pass the received current through the current transformer via the first and second parts inducing a current in the current transformer. The induced current may be useable to measure the current from the current source. Methods for fabricating the current measurement connector may include die casting the first and second parts and press fitting the first and second parts at the respective joints through the current transformer. Methods for use may include withstanding a fault current pulse and dissipating heat associated with the pulse via the first and second parts.

    Abstract: A proximity sensor includes a relatively simple temperature compensation circuit, and includes a variable gain oscillator, a temperature sensor circuit, and a proximity determination circuit. The variable gain oscillator has a gain that varies with the proximity of a target to a sensor coil, generates an oscillating electrical signal having a substantially constant amplitude magnitude, and generates an energy signal representative of the electrical energy needed to sustain oscillations. The temperature compensation circuit senses proximity sensor temperature and supplies a temperature signal representative thereof, and the proximity determination circuit, based on the energy signal, supplies a proximity signal representative of target proximity to the sensor coil. The proximity determination circuit includes a comparator and a fixed resistor network. The comparator circuit supplies the proximity signal. The fixed resistor network is coupled between the temperature sensor circuit and comparator circuit and supplies a temperature compensation signal to the comparator circuit.
