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.
