Abstract
An active antenna test system is described. The active antenna test system comprises an active antenna unit comprising: a plurality of antenna elements; at least one processor; a plurality of transceiver modules operably coupled to the at least one processor and arranged to receive at least one first baseband signal for transmission via at least one of the plurality of antenna elements and arranged to pass at least one second baseband signal thereto received and down-converted from at least one of the plurality of antenna elements; and at least one switching module operably coupling the plurality of antenna modules to the plurality of transceiver modules. The active antenna test system also comprises at least one communication test equipment, such as a radio frequency, RF, test module and at least one baseband processor. The active antenna unit further comprises at least one externally connectable radio frequency, RF, test port operably coupled to the at least one switching module and arranged to externally couple the at least one communication test equipment to at least one of the plurality of transceiver modules for conductive testing.
