    摘要: An example contact head includes coaxial contacts configured for transmission of radio frequency (RF) signals or digital signals between a test system and a device under test (DUT). Each of the coaxial contacts is configured to target a specific impedance. Each of the coaxial contacts includes a coaxial structure having an open-curve shape. The coaxial structure includes a spring material that bends in response to applied force and that returns to the open-curve shape absent the applied force. The coaxial structure includes a center conductor terminating in a contact pin and a return conductor separated by a dielectric from the center conductor. At least part of the center conductor and the return conductor include an electrically-conductive material. Flexible contacts on the coaxial contact include the electrically-conductive material.

    摘要: An interrogator plug for interfacing with the output socket of a pulsed power system to provide external leads engagable by a volt measurement device. The interrogator plug is sized to replicate a conventional plug such that the interrogator plug can be inserted into the output plug. The interrogator plug has lead assemblies positioned to engage the contacts of the output socket ordinarily engaged by conventional plugs. The interrogator plug can also include a divider circuit linked to a coaxial output for providing a reduced voltage current having an operational voltage safely measurable by conventional voltmeters.

    摘要: The invention relates to a device, a probe, and a method for the galvanically decoupling transmission of a measuring signal. A microwave signal is supplied by a transceiver (1) to a sensor (3) by means of a galvanically decoupled waveguide (2). The signal is partially reflected in the sensor (3), the amplitude, phase and/or polarization of the reflected microwave signal containing the information relating to the measuring value. The reflected microwave signal runs through the same waveguide (2) back to the transceiver (1) and is evaluated therein. The invention provides a more simple and economical structure than conventional devices of prior art, as a voltage supply is not required especially on the sensor side as a result of the reflection. In this way, the sensor (3) can also be produced in a very compact manner, minimizing the influence of the measuring signal through the sensor (3).
