    摘要： Probe systems and methods are disclosed herein. The methods include directly measuring a distance between a first manipulated assembly and a second manipulated assembly, contacting first and second probes with first and second contact locations, providing a test signal to an electrical structure, and receiving a resultant signal from the electrical structure. The methods further include characterizing at least one of a probe system and the electrical structure based upon the distance. In one embodiment, the probe systems include a measurement device configured to directly measure a distance between a first manipulated assembly and a second manipulated assembly. In another embodiment, the probe systems include a probe head assembly including a platen, a manipulator operatively attached to the platen, a vector network analyzer (VNA) extender operatively attached to the manipulator, and a probe operatively attached to the VNA extender.

    摘要： Methods and apparatus for testing devices using serially controlled resources have been described. Examples of the invention can relate to an apparatus for testing a device under test (DUT). In some examples, an apparatus can include an integrated circuit (IC) having a serialized input coupled to test circuits, the test circuits selectively communicating test signals with the DUT responsive to a test control signal on the serialized input.

    摘要： Rotating contact elements and methods of fabrication are provided herein. In one embodiment, a rotating contact element includes a tip having a first side configured to contact a device to be tested and an opposing second side; and a plurality of deformed members extending from the second side of the tip and arranged about a central axis thereof, wherein the tip rotates substantially about the central axis upon compression of the plurality of deformed members.
