    Abstract: A test system can include a probe suitable to be coupled between a test measurement device and a device under test (DUT). The probe can include a signal input to receive an active signal from the DUT and a signal output to provide the active signal to the test measurement device. The probe can also include an input ground to connect to the DUT ground and an output ground to connect to the test measurement device ground. A probe ground connection checking device can automatically determine whether the probe ground connections to the DUT ground and test measurement device ground are solid.

    Abstract: A test and measurement system including a test and measurement instrument, a probe connected to the test and measurement instrument, a device under test connected to the probe, at least one memory configured to store parameters for characterizing the probe, a user interface and a processor. The user interface is configured to receive a nominal source impedance of the device under test. The processor is configured to receive the parameters for characterizing the probe from the memory and the nominal source impedance of the device under test from the user interface and to calculate an equalization filter using the parameters for characterizing the probe and nominal source impedance from the user interface.

    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.

    Abstract: A test probe tip can include a compliance member or force deflecting assembly and a tip component. The compliance member or force deflecting assembly can include a plunger component and a barrel component to receive the plunger component, wherein the plunger component is configured to slide axially inside the barrel component. The test probe tip can also include a spring mechanism within the barrel component to act on the plunger component, and a resistive/impedance element coupled with the plunger component at one end and with the tip component at the opposite end, the resistive/impedance element including at least one rod having a semi-cylindrical form and a resistive material situated thereon.
