Abstract: Various embodiments are presented of a system including an alignment fixture for testing (e.g., rapidly and cheaply) phased array antennas and other devices configured for radio frequency (RF) transmission and/or reception. A device to be tested (e.g., the device under test (DUT)) may be positioned in a testing position by the alignment fixture. The alignment fixture may provide a configurable level of friction to retain the DUT in the testing position. The alignment fixture may provide isolation from electromagnetic interference for the DUT while in the testing position.
