  • Publication number: 20190353683
    Abstract: A test-probe tip having a tip component, a resistive element, and a compliance member. The tip component is configured to electrically connect to a device under test at a first end of the tip component. The resistive element is electrically connected to a second end of the tip component along a signal-flow axis. The resistive element is configured to provide electrical impedance to an electrical signal passing through the resistive element. The compliance member is configured to allow movement of the tip component in a first direction when a mechanical force applied to the tip component in the first direction and to cause movement of the tip component in an opposite, second direction when the mechanical force applied to the tip component is removed or reduced. Architectures for the resistive element are also described.

  • Patent number: 10215776
    Abstract: Test and measurement probes include a body, an adjustable member moveably coupled to the body and having a changeable position relative to the body, and a transducer subsystem structured to measure the position of the adjustable member and configured to output a position signal indicative of the position of the adjustable member. A change in the position of the adjustable member causes a change in an electrical characteristic of the probe. A position-dependent correction factor may be used to correct the change in the electrical characteristic. Methods of compensating for a change in a response of a test and measurement system include monitoring a position sensor output to detect a position change of a first part of a probe relative to a second part, determining that the position sensor output value has crossed a boundary value between a first and second range, and applying a compensation factor corresponding to the second range to modify the response of the system.

    Abstract: A probe for making electrical contact with a device-under-test test point includes a body, a rigid member capable of travelling linearly with respect to the body, a flexible arm having a test point contact at one end and fastened to the rigid member at the other end, and a flexible linkage fixed to the body and to the flexible arm. The flexible linkage is structured to cause the flexible arm to bend in response to travel of the rigid member in one direction, and to cause the flexible arm to unbend in response to travel of the rigid member in the other direction. A second flexible arm may be included, the two arms opening and closing to change the distance between test point contacts. A light source may be disposed on a portion of the flexible linkage that simultaneously articulates to automatically track the orientation of the test point contact.
