Abstract: Improved electrical testing of N-port beamforming devices is provided. For testing, an N:1 electrical network is connected to the N ports of the device under test to provide a single test port. This mode of testing can be used to determine parameters of interest (e.g., far field radiation patterns etc.) of the device under test more rapidly than with antenna range testing or with characterization of each port of the device under test. The N:1 electrical network can be passive or active. The N:1 electrical network can be integrated in a probe head to provide probe array testing of beamforming devices. Alternatively, the N:1 electrical network can be integrated with the device under test to provide onboard testing capability.
