Agilent Technologies has announced a scalable laboratory instrument that enables quicker, more accurate testing of MIMO (multiple-input/multiple-output) receivers earlier in the design cycle. Providing what the company calls the market’s best simulation of real-world conditions, the new N5106A PXB MIMO-receiver tester, enables significant reductions in the time to develop and qualify new products. By minimizing design uncertainty and setup time and providing the performance and scalability to meet future test needs, the instrument transforms MIMO test, according to Agilent. Its capabilities make the new tester ideal for R&D engineers who develop and integrate MIMO receivers for 3GPP (third-generation-partnership-project), LTE (long-term-evolution), WiMax (worldwide-interoperability-for-microwave-access), and emerging wireless standards.
The tester provides versatile signal-creation and channel-emulation for the latest LTE and WiMax standards. It supports 2×2 (two-transmitter/two-receiver), 2×4 (two-transmitter/four-receiver), and 4×2 (four-transmitter/two-receiver) MIMO with 120-MHz bandwidth and features custom MIMO-correlation settings—for example, channel models, antenna pattern, and correlation matrix. Signal Studio signal-creation software runs in the instrument and provides up-to-date standards-compliant signal creation.
Using the PXB, you can simulate real-world conditions in the lab to more quickly test corner cases and stress devices beyond standards requirements. You can also test coexistence to ensure design robustness earlier in the design process. Using Signal Studio, Advanced Design System software, or even a waveform-creation tool that you wrote yourself, you can sum the outputs of as many as four high-performance baseband generators to perform multiformat coexistence testing. Each baseband generator supports 120-MHz modulation bandwidth with 512M samples of playback memory for simulating long, complex signals. This approach enables earlier identification of problems, which allows you to design with greater confidence and thereby reduce uncertainties, minimize rework, and shorten time to market.
Seamless signal routing and automated power calibration minimize test time and eliminate the time-consuming system setup previously required for fading and multiformat coexistence-signal summing. Predefined test configurations further reduce test time and allow you to quickly define complex instrument settings. A GUI (graphical user interface) with drop-down menus speeds learning and provides quick selection of test settings such as MIMO-channel models and path configurations.
The tester features a scalable, high-performance platform based on a field-upgradable architecture. Adding support for the test needs of future technologies, such as 4G (fourth-generation) and higher-order MIMO implementations, requires only a cost-effective upgrade that you can perform in an hour. The architecture extends the instrument’s service life, maximizes your equipment investments, and reduces the cost of test by allowing you to use existing Agilent signal generators and analyzers and other RF-test equipment. Pricing depends on the system configuration and begins at $31,000.
