New PXI products sustain higher data streaming rates than ever before possible with an industry-standard test and measurement platform.
New PXI products, based on the PXI Express specification, include modular instruments, an embedded controller and RAID hard drive arrays, offers sustained hard drive recording and playback at 600Mbyte/s With these new data streaming capabilities, engineers can achieve higher sustained acquisition and generation rates, reduce test times and meet new application challenges

High-precision audio and vibration measurements
For the first time on the PXI platform, engineers can make precision audio and vibration measurements with the National Instruments NI4472.
Modules condition a range of sensor signals
National Instruments has released new Signal Conditioning Component modules for frequency to voltage conversion, integrated circuit piezoelectric accelerometers and RTDs.
Previous data streaming applications required dedicated, proprietary systems typically costing tens to hundreds of thousands of dollars.
The new NI PXIe-5442 16bit arbitrary waveform generator can stream from disk at the full rate of 100Msample/s (200Mbyte/s) for 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.

More measurement options from real-time software
The newest version of LabVIEW Real-Time offers more measurement options and improves development time with superior performance and easy-to-use networking functions.
The NI PXIe-5442 module complements the company's existing NI PXIe-5122 100Msample/s, two-channel digitiser 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 can also use the new NI PXIe-5442 module with the NI PXI-5610 2.7GHz RF upconvertor 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 PCI Express links, the new NI PXIe-8130 embedded controller delivers up to 4Gbyte/s of bandwidth to a PXI Express system.
The controller includes a 2.3GHz AMD Turion 64 X2 dual-core processor, ExpressCard slot and Gigabit Ethernet.
In addition, the new NI 8262 module and NI HDD-8263 and HDD-8264 external RAID hard drive enclosures offer sustained, long duration hard drive streaming rates of up to 600Mbyte/s.
The NI 8262 module provides a x4 cabled PCI Express link that can cable to the 3U HDD-8264, which includes twelve 250Gbyte SATA hard drives (3Tbyte), or the 1U HDD-8263, which includes four 250Gbyte SATA hard drives (1Tbyte).
PXI Express, an extension of the PXI specification, leverages commercial PC technology to offer the industry's highest bandwidth, lowest latency and highest-performance timing and synchronisation capabilities as well as software and hardware compatibility with the large installed base of existing PXI systems.
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. Request a free brochure from National Instruments ...
