摘要： A system and method for testing multiple-input-multiple-output (MIMO) devices under test (DUTs) with multiple radio frequency (RF) signal testers. Each tester receives one or more RF signals from one or more of the DUTs, and the testers are mutually coupled in a ring such that successive ones receive a trigger input signal from an upstream tester and provide a trigger output signal to a downstream tester. Each tester is responsive to its input trigger signal and its one or more RF signals by providing its output trigger signal such that its output trigger signal has an asserted state initiated in response to an assertion of its input trigger signal and a transcending of a predetermined magnitude by at least one of the one or more RF signals.

摘要： A method for testing a device under test (DUT) during a test sequence. In accordance with one embodiment, during a regular, pre-defined test sequence, data packets are transferred from a tester to a device under test (DUT) containing data related to at least one of an identification parameter of the DUT, an operational characteristic of the DUT and a request for data. Examples of such transferred data include address data for identifying the DUT (e.g., a unique media access control (MAC) address) and calibration data for controlling an operational characteristic of the DUT (e.g., signal power levels, signal frequencies or signal modulation characteristics). In accordance with another embodiment, the DUT retrieves and transmits data to the tester, either in response to the request for data or as a preprogrammed response to its synchronization with the tester.
