摘要： A method for wireless communications testing using downlink (DL) signal transmissions from an access point to a mobile terminal and uplink (UL) signal transmissions from said mobile terminal to said access point. Accurate block error rate (BLER) testing of LTE mobile devices in a wireless signal environment is enabled by preventing repeated transmissions of the same downlink (DL) data block that would normally follow reception of uplink (UL) transmissions of negative UL acknowledgments (NACKs) caused by failures to decode prior DL data transmissions, thereby producing cumulative NACK counts accurately reflecting data reception errors.

摘要： Methods for testing multiple data packet signal transceiver devices under test (DUTs) with a shared tester. The DUTs transmit their data packet signals until predetermined numbers of data packets have been transmitted or predetermined time intervals expire, following which, each DUT awaits a synchronization request to begin transmitting data packets to the tester. Alternatively, the tester determines when its receiver is available for receiving data packets, following which, synchronization requests are sent to respective DUTs to initiate their transmissions of data packets to the tester. Further alternatively, power levels among data packets initially transmitted from the DUTs are monitored to determine when they are indicative of them having settled. As each DUT data packet signal power settles, a status signal indicating the settled nature of each DUT is provided to the tester which then begins receiving the respective DUT data packet signals, as they settle in power, for analysis.
摘要翻译：用共享测试仪测试多个被测数据分组信号收发器设备（DUT）的方法。 DUT传送其数据分组信号，直到已经发送预定数量的数据分组或预定的时间间隔到期，之后每个DUT等待同步请求开始向测试者发送数据分组。或者，测试者确定其接收机何时可用于接收数据分组，随后将同步请求发送到相应的DUT以发起数据分组到测试者的传输。另外替代地，监视从DUT发送的数据分组中的功率电平，以确定它们何时指示它们已经结算。当每个DUT数据分组信号功率稳定时，向测试者提供指示每个DUT的稳定性质的状态信号，然后测试器开始接收相应的DUT数据分组信号，因为它们定时处理，用于分析。

摘要： A system and method for testing multiple wireless data packet signal transceiver devices under test (DUTs) with dynamic signal interference compensation. Transmit data packets originating from other DUTs are monitored during receive signal testing of a selected DUT for concurrent occurrences of transmit and receive data packets. From this, it can be determined whether a failure to receive a responsive data packet, such as an acknowledgement, from the selected DUT is likely due to interference from a transmit data packet from another DUT being at least substantially concurrent with the receive data packet to which the selected DUT was expected to respond. If so, one or more receive data packets can be added to the receive signal sequence to extend the test and determine an accurate packet error rate (PER) without requiring a repeat of the full test.

摘要： System and method for implementing a Vector Network Power Meter (VNPM) as a new class of electronic test instrument that uses a novel topology based upon a reflectometer to combine the functionality of a Power Meter with that of a Vector Network Analyzer (VNA). The VNPM overcomes application limitations of the two existing classes of test instruments, including parallel and simultaneous measurement capability, in-circuit operation, and improved accuracy and repeatability by eliminating the calibration of interconnecting cabling. Also provided are alternate implementations of a correlator for the reflectometer which reduce the size and complexity of the correlator while extending its frequency range without limit.

摘要： A system and method to facilitate wireless testing of a radio frequency (RF) multiple- input, multiple-output (MIMO) signal transceiver device under test (DUT). With the DUT operating in a controlled electromagnetic environment, the tester transmits multiple test signals wirelessly to the DUT. Signal phases of the respective test signals transmitted by the tester are controlled in accordance with feedback signal data from the DUT. Magnitudes of the respective test signals can also be controlled in accordance with such feedback signal data, thereby enabling dynamic optimization of the wireless communication channel condition number k(H).

摘要： System and method for testing a radio frequency (RF) device under test (DUT) communicating using multiple radio access technologies (RATs). Single data signal sequences having characteristics of multiple RATs as prescribed by signal standards are exchanged between a tester and DUT. The tester and DUT process received signal sequences substantially in parallel with their reception. A pattern of contemporaneous signal sequence reception and processing continues for as many RATs as the DUT is capable of supporting.

摘要： A system and method for testing multiple-input-multiple-output (MIMO) devices under test (DUTs) with multiple radio frequency (RF) signal testers. Each tester receives one or more RF signals from one or more of the DUTs, and the testers are mutually coupled in a ring such that successive ones receive a trigger input signal from an upstream tester and provide a trigger output signal to a downstream tester. Each tester is responsive to its input trigger signal and its one or more RF signals by providing its output trigger signal such that its output trigger signal has an asserted state initiated in response to an assertion of its input trigger signal and a transcending of a predetermined magnitude by at least one of the one or more RF signals.

摘要： A local oscillator (LO) of a test system is set to an initial frequency whereupon a device under test (DUT) transmits a radio frequency (RF) signal to the test system. Characteristics of the RF signal are measured with the test system and used to identify magnitudes and frequencies of spurious signal products. The LO of the test system is reset to one or more subsequent frequencies that are offset from the initial frequency. One or more subsequent RF signals are transmitted from the DUT to the test system, with the DUT maintaining its original signal settings. Characteristics of the subsequent RF signals are measured with the test system and used to identify magnitudes and frequencies of spurious signal products for each of the subsequent LO frequencies. The spurious signal products that have shifted in frequency for each of the subsequent LO frequencies as self-generated signal products can then be identified.
