A beamformer for providing signals from a device under test (DUT) and an emulator is disclosed. The beamformer includes: a radio frequency (RF) interface configured to receive a plurality of radio beams and convert a data stream comprising a plurality of radio beams from analog signals to digital signals; a radio samples processor configured to receive the digital signals, decouple data samples from the plurality of radio beams, and recombine the data samples to provide a single data stream to a corresponding single device used by an end-user; and a local processor adapted to dynamically adjust operational parameters in the radio samples processor of the single data stream.

Beam aquisition and configuration device

A method for 5G digital beamforming testing includes receiving emulated UE spatial positions. The method includes computing phase vectors for the emulated UEs based on the emulated UE spatial positions and communicating the phase vectors to a DUT. The method includes receiving beam weight sets from the DUT and storing the beam weight sets. The method includes computing scores for the emulated UE spatial positions from the beam weight sets and the phase vectors, and receiving, from the DUT, spatial streams and identifiers of beam weight sets to be used to transmit the spatial streams to the emulated UEs. The method includes identifying, using scores corresponding to the beam weight sets to be used to transmit the spatial streams to the emulated UEs, associations between the spatial streams and the emulated UE spatial positions. The method includes processing data in the spatial streams using the emulated UEs.
