Abstract
A system tests a device under test (DUT) that includes an antenna. The system includes a probe antenna, a network emulator, and a near-field antenna. The probe antenna measures beam characteristics of a beam-locked beam emitted over the air by the antenna of the DUT as the DUT is moved relative to the probe antenna during testing of the DUT. The network emulator emulates a base station of a communications network in communications with the DUT. The near-field antenna maintains a call link between the network emulator and the DUT using surface waves between the near-field antenna and the DUT as the DUT is moved relative to the probe antenna.
