  • Patent number: 11057291
    Abstract: A test system tests a DUT configured as a wireless device. A golden device is configured to provide bidirectional communication between it and the DUT. A measurement device acquires a first signal S1 including at least an output SDUT of the DUT. An interface unit monitors a second signal S2 including at least one of the output SGD of the golden device and the output SDUT of the DUT. In response to the occurrence of a predetermined waveform pattern in the second signal, the interface unit generates a trigger signal TRIG for instructing the measurement device to acquire a signal.
