摘要： System and method for testing transmission and reception performance of a data packet signal transceiver device under test (DUT). Data packet signals transmitted by a tester with a tester transmit output power (TTOP) contain trigger frames that include data corresponding to a reported tester transmit power (RTTP) of the data packet signals, and a desired received signal strength (TRSS) of DUT data packet signals to be received by the tester. Based on received signal strength of the tester data packet signals reported by the DUT (DRSS), responsive DUT data packet signals having a DUT transmit output power of RTTP-DRSS+TRSS. Successive repetitions of such tester and DUT data packet signals for multiple combinations of values of the TTOP, RTTP and DRSS enable testing transmission and reception performance of the DUT, including determining minimum and maximum DUT transmission power levels, with minimal signal interactions between tester and DUT.

摘要： Method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) including communicating via each one of multiple available signal channels. Data packets exchanged between a tester and DUT as a normal part of a communication link initiation sequence are exchanged in such a manner that the tester transmits with varied signal power via all available channels simultaneously, thereby ensuring that a properly working DUT will transmit in response to reception of tester data packets having sufficient signal power. For example, in the case of a Bluetooth low energy transceiver, advertisement, scan request and scan response data packets can be used in such manner.

摘要： Method for testing multiple signal transceiver devices under test (DUTs), such as data packet signal transceivers, with a shared DUT testing resource, such as a tester having a single vector signal generator (VSG) and a single vector signal analyzer (VSA). Requests by the DUTs for access to tester resources (e.g., to receive signals from the signal generator or provide signals to the signal analyzer) are prioritized based upon tester availability and whether the requesting DUT requires sole access or can share access to the tester. If the tester is unavailable, DUT requests are queued according to their respective priorities to await tester availability. As a result, access to shared tester resources can be managed dynamically to minimize test time while testing multiple DUTs concurrently.

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.

摘要： A method for testing a data packet signal transceiver device under test (DUT) that minimizes time lost due to waiting for respective power levels of data packets transmitted by the DUT to settle at the desired nominal value for transmit signal testing. In accordance with exemplary embodiments, signals transmitted by the DUT during receive signal testing, e.g., as acknowledgement data packets, are transmitted at the nominal value for transmit signal testing, thereby allowing sufficient time for individual data packet signal power levels to settle and remain consistent at the nominal value by the time receive signal testing is completed and transmit signal testing is to begin.
