Claim 0:
1. An automated test equipment for testing a device under test the automated test equipment comprising:
a stimulus module; a measurement module; a loopback; a first switch; a second switch; and a load board interface wherein the load board interface comprises: a first radio frequency port; and a second radio frequency port,
wherein the first and second radio frequency ports are operable to be coupled to respective ports of a load board associated with the load board interface, wherein the device under test is operable to couple to the load board to receive and to provide test signals between the load board interface and the respective ports of the load board,
wherein further the first switch is operable to couple the first radio frequency port to the stimulus module when the first switch is set in a first switching state of the first switch,
wherein further the second switch is operable to couple the second radio frequency port to the measurement module when the second switch is set in a first switching state of the second switch, and
wherein further the first switch is operable to couple the first radio frequency port to a first end of the loopback when the first switch is set in a second switching state, and the second switch is operable to couple the second radio frequency port to a second end of the loopback when the second switch is set in a second switching state, wherein a loopback signal path is formed between the first and second radio frequency ports when the first and second switches are in the respective second switching state.
