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 there-between despite, for example, variable positioning of the device-probing ends of the network on the probing areas. 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. Because the transmission structure uniformly transfers signals, the relative condition of the signals as they enter or leave each end will substantially match the condition of the signals as measured or presented by the reference unit, thereby enabling calibration of the network in reference to the device-probing ends. The assembly is particularly well-adapted for the evaluation of probe measurement networks of the type used for testing plan…
