Aeroflex has launched its PXI Maestro, a next-generation automatic test solution for use in wireless device manufacturing that lowers the cost of test and accelerates test development.
PXI 3000 is a proven platform for modern manufacturing test of cellular, wireless LAN, GPS, and Bluetooth wireless devices, according to the company. PXI Maestro adds significant capability to the PXI 3000 platform and provides a production-ready test system with integrated chipset-specific device control and the ability to test multiple devices in parallel.
Up to eight devices can be tested at the same time using a dual channel Multi-UE architecture that provides eight bi-directional RF ports in a single 19" chassis. Greater test speed, reduced test footprint, and significantly low costs make Maestro and PXI 3000 the best choice for all high volume manufacturing test applications.
With shorter product life cycles and increased device complexity, test system development cycles must be completed in weeks rather than months. PXI Maestro sets a new speed benchmark for non-signaling mode RF test system integration and test execution.
PXI Maestro's ability to test multiple devices in parallel is achieved using an innovative multi-way active RF combiner module that supports connection of up to four devices to each channel. This approach achieves an almost four-fold throughput improvement per radio when compared with an equivalent serial test method, for virtually the same cost.
PXI Maestro is optimised for speed regardless of whether implemented to test a single device or multiple devices in parallel. The key to RF test system efficiency lies not just in raw test speed but also in optimizing test equipment utilization. Efficient test system development minimizes equipment idle time both within and across measurement steps.
The product features a multi-threaded intelligent sequencer to exploit the benefits of modern multi-core PCs. This ensures that different tasks both within a measurement step and across a measurement sequence are overlapped or executed concurrently rather than sequentially as with conventional instrumentation.
Multiple threads manage device control, test equipment setup and measurement processing in a tightly coupled manner. Where multiple different measurement are performed at the same test condition then PXI Maestro saves time and executes them in parallel on the same captured data.
PXI Maestro is an extension to the existing Aeroflex PXI 3000 Measurement Suites for GSM/EDGE, WCDMA, LTE FDD and WLAN, and is supplied with built-in support for the direct control of leading cellular chipsets.
