SYSTEM AND METHOD FOR TESTING A DEVICE UNDER TEST (DUT) CAPABLE OF DETERMINING RELATIVE TIMES OF ARRIVAL OR ANGLES OF ARRIVAL OF MULTIPLE RADIO FREQUENCY SIGNALS

摘要

System and method for providing variable time delays with high temporal granularity and consistent broadband delay performance for testing of time-of-arrival (ToA) or angle-of-arrival (AoA) performances of radio frequency (RF) signal transceivers. Multiple delays may be imparted to a common RF signal to provide multiple delayed RF signals corresponding to RF signals originating from a source location and received at various locations having respective position coordinates relative to respective orthogonal axes, plus another delayed RF signal corresponding to a RF signal originating from the source location and received at a location at an intersection of the orthogonal axes.
