Claim:
1. A measurement system for characterizing a device under test, DUT, wherein impedance is controlled or varied over a set of measurement conditions and a parameter or a set of parameters measured for each measurement condition, said measurement system comprising: at least one impedance control device, signal separation hardware connected with said impedance control device, receiving means connected with the signal separation hardware for measuring electrical quantities related to characteristics of said DUT and for converting said measured electrical quantities, a data processing unit connected to said receiving means and adapted to provide characteristics of said device under test based on said converted electrical quantities, whereby said at least one impedance control device is integrated inside said signal separation hardware, wherein a distance from the at least one impedance control device to the DUT—when the DUT is coupled to the measurement system—is shorter than a wavelength of at least one signal used in measuring the electrical quantities.
