Abstract:
1. A measuring system for determining scattering parameters of an electrical device under test on a substrate, comprising: a measuring device including at least one measuring channel and measuring probes connected to said at least one measuring channel and which are designed for contacting, with or without physical contact, an electrical signal guide belonging to the electrical device under test in the electronic circuit; a first positioner being provided for each of said measuring probes, for positioning the measuring probes in three dimensions in space, said first positioners having a motorized drive; at least one sensor for each of said measuring probes for detecting an absolute position of the measuring probe in space, a position of the measuring probe relative to the electrical device under test, a position of the measuring probe relative to a position mark on an electronic circuit, or a position of the measuring probe relative to a signal line between the electrical device under test and the rest of the electronic circuit, or any combination thereof, and emitting a position signal to this effect to at least one first control unit; at least one first control unit connecting to the sensors to receive the position signals therefrom and actuating the first positioners in such a way that the measuring probes whose positions are detected by the sensors are situated in predetermined positions in space relative to the electrical device under test; at least one second positioner having a motorized drive and receiving the substrate mechanically for positioning the substrate in three directions in space; at least one second control unit for actuating the at least one second positioner; a data path for transmitting positional data from said sensors to said at least one second control unit; a data transmission path for transmitting data between the measuring device and said at least one first or second control unit; the first and second control units being integrated into a single control unit, the sensors detecting a position of the measuring probes relative to a position mark on the electronic circuit or the substrate and emitting a position signal to this effect to said at least one first control unit.
