摘要： Method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) including communicating via at least 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 selectively exchanged and suppressed to enable testing of the DUT without requiring inclusion of special drivers within the DUT, special test software within the tester or establishment of a synchronized communication link between the tester and DUT. 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 calibrating an over-the air (OTA) test system for testing multiple radio frequency (RF) data packet signal transceiver devices under test (DUTs), as well as using such a calibrated OTA test system for performing such tests. Calibration is achieved by placing a known good device (KGD) in multiple defined locations within the OTA test system, radiating the KGD with RF test signals at each location, and collecting from the KGD at each location channel quality information identifying optimal RF test signal sub-band channels for ensuring reliable communications within the test system. Use of such system includes placing multiple DUTs at the defined locations within the OTA test system and communicating with them wirelessly via the identified optimal RF test signal sub-band channels.

摘要： Method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) via a wireless signal medium that enables final functional testing of a fully assembled DUT without requiring wired signal connections. System performance characteristics indicative of manufacturing assembly defects, such as defective antennas or subsystem connections, can be performed using over the air (OTA) test signals communicated wirelessly between the DUT and a tester. By using actual DUT performance characteristics determined during earlier manufacturing tests, such as receiver sensitivity and transmitter power, and known power levels available from the tester transmitter, the OTA signal path loss (i.e., attenuation of the wireless signal) can be estimated and used to confirm the final state of system operation.

摘要： System and method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) to enable use of measured packet error rate (PER) to determine transmit signal quality and thereby estimate error vector magnitude (EVM) of the DUT. By using a reference RF data packet signal transceiver having device characteristics and capabilities similar to the DUT including a low noise figure, in place of a formal test instrument with a significantly higher noise figure, significantly lower power DUT transmit signals can be tested, since the additional SNR is not required to determine transmit signal quality, thereby enabling reliable testing of transmit signal quality of the lower power signals from the DUTs. With a calibrated reference RF data packet signal receiver, a reduction in sensitivity as compared to the calibrated sensitivity indicates a reduced transmit signal quality of the received packet.

摘要： Method for testing implicit beamforming performance of a multiple-input multiple-output (MIMO) radio frequency (RF) data packet signal transceiver device under test (DUT). The data packet signals forming the sequential data packet signal transmissions used for beamforming are produced with a selectively varied phase difference and conveyed via internal RF signal paths to external transmit terminals. Combining these transmitted data packet signals produces a combined data packet signal in which a peak power occurs during which a particular phase difference is being induced between the sequential DUT data packet signal transmissions used for the beamforming. This phase difference corresponds to the difference in RF signal phase lengths between the internal RF signal paths of the DUT, and is thereby indicative of the amount of phase shift needed between the sequential DUT data packet signal transmissions used for the beamforming to enable optimal implicit beamforming performance.
摘要翻译：用于测试多输入多输出（MIMO）射频（RF）数据分组信号收发器设备（DUT）的隐含波束成形性能的方法。形成用于波束形成的顺序数据分组信号传输的数据分组信号通过选择性地变化的相位差产生并经由内部RF信号路径传送到外部发送终端。组合这些发送的数据分组信号产生组合的数据分组信号，其中发生峰值功率，在该峰值功率期间，在用于波束形成的连续的DUT数据分组信号传输之间正在感应出特定的相位差。该相位差对应于DUT的内部RF信号路径之间的RF信号相位长度的差异，因此指示用于波束成形的顺序DUT数据分组信号传输之间所需的相移量，以实现最佳隐含波束成形性能。

摘要： Circuitry for shifting a phase of a radio frequency (RF) signal. Mutually dissimilar and electrically coupled portions of an electromagnetic transmission line pattern on one side of a substrate interact with another electromagnetic transmission line pattern on the opposing substrate side to convey a RF signal with a phase shift that is determined by the RF signal frequency and respective dimensions of the electromagnetic transmission line patterns and is substantially constant over a wide bandwidth. With multiple implementations of such opposing electromagnetic transmission line patterns having different pattern dimensions and coupled between RF signal switches, multiple phase shifts can be selectively provided.

摘要： A system and method for enabling automated testing of wireless data packet signal transceiver devices under test (DUTs). One or more DUTs are enclosed inside respective chambers within a shielded enclosure providing electromagnetic shielding for its interior region. Each DUT is powered by an internal power source and its radio frequency (RF) signal port is connected to an external RF signal interface at an outer wall of the shielded enclosure. An anchor at an outer wall of the shielded enclosure enables mechanical engagement with and physical displacement of the shielded enclosure, thereby allowing DUTs to be manipulated using pick and place automation devices for engagement with and connection to automated test equipment. Such test equipment can be assembled into vertically stacked RF signal test stations with which shielded DUT enclosures are engaged by physically mating their respective power and RF signal ports using the pick and place automation device.

摘要： A system and method for facilitating wireless testing of a radio frequency (RF) signal transceiver device under test (DUT). Using multiple antennas within a shielded enclosure containing the DUT, multiple wireless RF test signals resulting from a RF test signal radiated from the DUT can be captured and have their respective signal phases controlled in accordance with one or more signal characteristics, including their respective signal power levels, their respective signal phases as received, and a signal power level of a combination of the received signals. Such phase control of the captured wireless RF test signals can be performed individually for any DUT tested within the shielded enclosure, thereby providing compensation for the multipath signal environment within the shielded enclosure irrespective of the placement of the DUT, and thereby simulating a wired test signal path during wireless testing of the DUT.
