a system and method for testing a wireless data packet signal transceiver device under test by using dut control circuitry separate from a tester to access and execute test program instructions for controlling the dut during testing with the tester . the test program instructions can be provided previously and stored for subsequent access and execution under control of the tester or an external control source , such a personal computer . alternatively , the test program instructions can be provided by the tester or external control source immediately prior to testing , such as when beginning testing of a dut with new or different performance characteristics or requirements . accordingly , specialized testing of different duts while accounting for differences among various chipsets employed by the duts can be performed in coordination with a standard tester configuration without need for reconfiguring or reprogramming of the tester .
