Abstract: A single radio equipment test device includes a control unit for testing a plurality of antennas, (e.g., an antenna array). The control unit includes a first interface to operatively couple the control unit to an antenna under test, (e.g., arranged in a test chamber). The control unit further includes a second interface to operatively couple the control unit to a reference antenna, (e.g., also arranged in the test chamber). The control unit is configured to control and/or monitor the antenna under test and the reference antenna.
