System and method for testing radio frequency device under test capable of communicating using multiple radio access technologies
View Patent ↗System and method for testing a radio frequency (RF) device under test (DUT) communicating using multiple radio access technologies (RATs). Single data signal sequences having characteristics of multiple RATs as prescribed by signal standards are exchanged between a tester and DUT. The tester and DUT process received signal sequences substantially in parallel with their reception. A pattern of contemporaneous signal sequence reception and processing continues for as many RATs as the DUT is capable of supporting.
