SYSTEM AND METHOD FOR SYNCHRONIZED TRIGGERING OF TEST EQUIPMENT FOR TESTING MIMO TRANSCEIVERS

摘要

A system and method for testing a multiple input and output (MIMO) device under test (DUT) by a plurality of radio frequency (RF) signal testers. Each checker receives one or more RF signals from one or more DUTs, and the checkers are coupled together in a circle such that the continuous checker receives a trigger input signal from an upstream checker and provides a trigger output signal to a downstream checker. Each checker provides its output trigger signal such that its output trigger signal has an asserted state that starts in response to an assertion of its input trigger signal and at least one of the one or more RF signals exceeded a predetermined magnitude. Responsive to the trigger signal and one or more RF signals thereof.
