System for evaluating probing networks
First Claim
1. A method for evaluating signal conditions in a probe measurement network of the type having a plurality of separate measurement channels, each of said measurement channels communicating through a corresponding device-probing end included on a probe tip array, said method comprising:
- (a) providing an interconnect assembly including a base having an upper face, a first conductive planar probing area on said upper face, and a reference junction, said reference junction being connected to said first conductive planar probing area by a high-frequency transmission structure including a transmission line;
(b) placing the respective device-probing end of a first of said measurement channels into contact with said first planar probing area, transmitting a high-frequency signal through said first one of said measurement channels, said transmission line, and said reference junction and, thereafter, measuring said signal;
(c) repeating step (b) for another of said plurality of measurement channels; and
(d) evaluating the relative signal conditions in different ones of said measurement channels by comparing the measured signals.

Abstract
An interconnect assembly for evaluating a probe measurement network includes a base, respective inner and outer probing areas in mutually coplanar relationship on the upper face of the base, a reference junction, and a high-frequency transmission structure connecting the probing areas and the reference junction so that high-frequency signals can be uniformly transferred therebetween. A preferred method for evaluating the signal channels of the network includes connecting a reference unit to the reference junction and successively positioning each device-probing end that corresponds to a signal channel of interest on the inner probing area.
