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. ## Claims ### Claim 1 A method of testing a radio frequency (RF) device under test (DUT) capable of communicating using a plurality of radio access technologies (RATs), comprising: receiving, with a DUT from a tester during a plurality of successive time intervals, one or more RF data signals having a plurality of mutually distinct signal characteristics in accordance with a plurality of RATs, wherein, during first and second adjacent ones of said plurality of successive time intervals, said one or more RF data signals have at least first and second mutually distinct signal characteristics in accordance with first and second ones of said plurality of RATs, respectively;
