Abstract
A system and method for communicating information from a device under test (DUT) to a computer or person outside of a shielded testing chamber. The DUT can be, for example, a cellular device, that is being verified for cellular transmission or regulatory compliance. In addition to the cellular transmissions, the DUT can communicate information outside the shielded testing chamber via additional electromagnetic signals that are not sent via a cable, thereby obviating the need for a cable inside of the shielded testing chamber. The absence of a cable minimizes interference in the chamber because a cable can act as an antenna and interfere with the cellular transmissions being transmitted.
Claims20
A system for verifying a device under test (DUT) comprising:
- a shielded testing chamber;
- an antenna configured for communicating with a DUT within the shielded testing chamber using a first wireless communication at a first wireless frequency;
- a detector configured for communicating with a DUT within the shielded testing chamber using a second wireless communication at a second wireless frequency;
- a processor outside the shielded testing chamber and communicatively coupled to the antenna and to the detector, thereby obviating the need for a cable for communication between the DUT and the processer, the processor configured to output test results to verify operation of the DUT based on the first wireless communication and the second wireless communication.
A device under test (DUT) comprising:
- a processor configured to perform a wireless verification test for verifying DUT operation and to provide wireless test information associated with the wireless verification test to an external detector;
- a wireless transceiver communicatively coupled to the processor and configured to communicate with an external antenna via a first wireless frequency;
- and
- an output communicatively coupled to the processor and configured to output the wireless test information to the external detector via a second wireless frequency.
A computer-readable medium having a computer program for verifying wireless communication from a device under test (DUT) comprising:
- receiving a first wireless communication from the DUT comprising a wireless packet;
- receiving a second wireless communication from the DUT comprising wireless test information;
- generating test results for verifying DUT operation based on the wireless test information and the first wireless communication, wherein the wireless test information is different from the first wireless communication;
- and
- outputting the test results to determine whether the DUT satisfies test requirements.
