Abstract:
1. A system adapted to measure electrical performance of a device under test (DUT) having two or more ports, comprising: a plurality of signal sources, wherein each signal source is connectable with an associated port of the two or more ports of the DUT; wherein the signal sources are synchronized and configured to generate signals simultaneously; wherein the signal sources are configured to each generate a signal having a frequency offset from each of the others of the signal sources by a known frequency delta; a plurality of first signal paths, wherein each first signal path is connectable with an associated port for obtaining reflected and transmitted signals simultaneously received from the DUT at the associated port; a plurality of second signal paths, wherein each second signal path is connectable with an associated port for obtaining incident signals received from the signal source connected with the associated port; a receiver for receiving the reflected, transmitted and incident signals obtained at the first signal paths and the second signal paths; and wherein the receiver is adapted to separate the reflected and the transmitted signals obtained from each of the first signal paths.
