Classification: CPC G | IPC G

Claim 13:
14. An automated test system for testing a device under test comprising:
a stimulus module; a measurement module; a loopback; a load board; a first switch; a second switch; and a load board interface, the load board interface comprising a first radio frequency port and a second radio frequency port, wherein the load board is configured to be mechanically and electrically docked to the load board interface, wherein the load board comprises at least one socket configured to connect to the device under test,
wherein the first and second radio frequency ports are configured to be coupled to respective ports of the load board, wherein the device under test is operable to couple to the load board via the socket to receive and to provide test signals between the load board interface and the respective ports of the load board,
wherein 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,
wherein 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,
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, and
wherein the socket is coupled to the first and second radio frequency ports via the load board.
