National Instruments has introduced new PXI products to help engineers sustain higher data streaming rates than ever before possible with an industry-standard test and measurement platform. The PXI productsbased on PXI Expressincludes modular instruments, an embedded controller and RAID hard drive arrays. The devices are said to offer sustained hard drive recording and playback at 600MBps.

The NI PXIe-5442 16bit arbitrary waveform generator can stream from disk at the full rate of 100MSPS (200MBps) for the generation of arbitrary waveforms up to several terabytes in length. Streaming from hard drives at the module's full rate reduces test times by eliminating the delay of uploading waveforms across slower instrument control buses. The NI PXIe-5442 module complements the company's existing NI PXIe-5122 100MSPS, two-channel digitizer and NI PXIe-6536/7 25/50MHz, 32-channel digital I/O modules to provide a full IF/baseband and mixed-signal streaming offering. Because PXI Express is compatible with all existing PXI modules, engineers also can use the NI PXIe-5442 module with the NI PXI-5610 2.7GHz RF upconverter to stream the full 20MHz real-time bandwidth from disk for RF generation and playback applications in communications and military/aerospace.

In addition to high-throughput PXI Express modular instruments, data streaming applications require a high-bandwidth system controller and RAID data storage. With four x4 PCIe links, the

NI PXIe-8130 embedded controller delivers up to 4GBps of bandwidth to a PXI Express system. The controller includes a 2.3GHz AMD Turion 64 X2 dual-core processor, ExpressCard slot and GbE. The NI 8262 module, NI HDD-8263 and HDD-8264 external RAID hard drive enclosures offer sustained, long duration hard drive streaming rates of up to 600MBps. The NI 8262 module provides a x4 cabled PCIe link that can cable to the 3U HDD-8264, which includes twelve 250Gbytes SATA hard drives (3Tbytes) or the 1U HDD-8263, which includes four 250Gbytes SATA hard drives (1Tbytes).

The new PXI Express products work with all existing PXI modules and software. All of the new products integrate with a variety of software including the NI LabVIEW 8.5 graphical development environment, which offers inherent parallelism and multithreading for high-speed streaming with PXI Express. Engineers can use existing code written for LabVIEW, the NI LabWindows/CVI ANSI C development environment and NI Measurement Studio for Microsoft Visual Studio code with these new products.

The NI PXIe-8130 embedded controller and NI PXIe-5442 arbitrary waveform generator are priced from $4,999 and $9,499, respectively. The NI 8262, HDD-8263 and HDD-8264 RAID are priced from $4,127.
