Patent ID: 11913987

Abstract:
An embodiment is an automated test equipment (ATE) for testing a device under test (DUT) which is connected to the ATE via a load board. The ATE comprises a stimulus module, a measurement module, a loopback, a first switch, a second switch, and a load board interface. The load board interface comprises a first radio frequency port and a second radio frequency port. The first and second radio frequency ports are configured to be coupled to the respective ports of the load board. The first switch is configured to couple the first radio frequency port to the stimulus module in a first switching state of the first switch and the second switch is configured to couple the second radio frequency port to the measurement module in a first switching state of the second switch. Further, the first switch is configured to couple the first radio frequency port to a first end of the loopback in a second switching state of the first switch and the second switch is configured to couple the second radio frequency port to a second end of the loopback in a second switching state of the second switch. When the first and second switches are in their respective second switching state, a loopback signal path is formed between the first and second radio frequency ports.
