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

An apparatus including a system for testing a device under test (DUT) capable of determining relative times of arrival (ToAs) or angles of arrival (AoAs) of multiple radio frequency (RF) signals, comprising:

• a RF signal source to provide a common RF signal;
• a plurality of signal terminals;
• and
• delay circuitry, in electrical communication with said RF signal source and said plurality of signal terminals, responsive to one or more control signals by imparting a plurality of variable delays comprising at least first and second ones of said plurality of variable delays to said common RF signal to provide to each of said plurality of signal terminals a respective one of a plurality of delayed RF signals including
• a first delayed RF signal of the plurality of delayed RF signals corresponding to a first RF signal originating from a source location and received at a first location having one of a first plurality of position coordinates relative to a first one of a plurality of orthogonal axes, and
• a reference delayed RF signal of the plurality of delayed RF signals corresponding to a reference RF signal originating from said source location and received at a reference location at an intersection of said plurality of orthogonal axes;
• wherein, responsive to the first and second ones of said plurality of variable delays, said first plurality of position coordinates includes first and second different ones of said first plurality of position coordinates corresponding to two of the plurality of the orthogonal axes.
