Abstract: 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.
