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.
Claims13
A test system structured to test a device under test configured as a wireless device, the test system comprising:
- a golden device structured to perform bidirectional communication with the device under test;
- a measurement device structured to capture a first signal including at least an output for the bidirectional communication of the device under test;
- and
- an interface unit structured to monitor a second signal including at least one of an output for the bidirectional communication of the golden device and the output for the bidirectional communication of the device under test, and to instruct the measurement device to capture the first signal in response to an occurrence of a predetermined waveform pattern in a time-domain waveform of the second signal.
An interface unit to be employed in a test system structured to test a device under test configured as a wireless device, wherein the test system comprises:
- a golden device structured to perform bidirectional communication with the device under test;
- and
- a measurement device structured to capture a first signal including at least an output for the bidirectional communication of the device under test,
- and wherein the interface unit comprises:
- a splitter structured to extract a part of a signal that propagates through a path for the bidirectional communication between the golden device and the device under test;
- a detector structured to detect a signal extracted by the splitter;
- and
- a timing generator structured to generate a trigger signal for instructing the measurement device to capture the first signal when a predetermined waveform pattern is detected in a time-domain waveform of an output of the detector.
