Abstract
An interconnect assembly for evaluating a probe measurement network includes a base, respective first, second and third device-probing areas arranged on an upper face of the base in spaced-apart relation so that first, second and third device-probing ends belonging to the measurement network can be simultaneously placed on these respective areas, 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 despite variable positioning of the device-probing ends on the probing areas. Because the transmission structure uniformly transfers signals despite variable positioning of the device-probing ends, the measurement network can be accurately calibrated with reference, in particular, to the device-probing ends of the network by a reference unit connected to the reference junction.
