SYSTEM AND METHOD FOR TESTING DATA PACKET TRANSCEIVERS HAVING VARIED PERFORMANCE CHARACTERISTICS AND REQUIREMENTS USING STANDARD TEST EQUIPMENT

摘要

A system and method for testing a wireless data packet signal transceiver device under test (DUT) 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.

主权项

1. An apparatus including a system for testing a wireless data packet signal transceiver device under test (DUT), comprising:
a data packet signal path for communicating with a DUT to convey a transmit data packet signal from said DUT and a receive data packet signal to said DUT; a tester coupled to said data packet signal path to receive said transmit data packet signal and provide said receive data packet signal, and responsive to one or more test commands by providing one or more test control signals; a DUT control signal interface for communicating with said DUT to convey at least one DUT control signal to said DUT; and DUT control circuitry coupled between said tester and said DUT control signal interface, responsive to at least said one or more test control signals by executing a plurality of test program operations to provide said at least one DUT control signal, wherein said transmit data packet signal is responsive to at least one of said receive data packet signal and said at least one DUT control signal.
