Austin, Tex. National Instruments (NI) has introduced PXI products with 600 Mbytes/s sustained data streaming. Based on the PXI Express specifications, these products include modular instruments, an embedded controller and RAID hard drive arrays that offer sustained hard drive recording and playback at 600 Mbytes/s.
The NI PXIe-5442 16-bit arbitrary waveform generator can stream from disk at the full rate of 100 MS/s (200 MB/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, said NI. The NI PXIe-5442 module complements the company's existing NI PXIe-5122 100 MS/s, two-channel digitizer and NI PXIe-6536/7 25/50 MHz, 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 2.7 GHz RF upconverter to stream the full 20 MHz real-time bandwidth from disk for RF generation and playback applications in communications and military/aerospace.
With four x4 PCI Express links, the NI PXIe-8130 embedded controller delivers up to 4 GB/s of bandwidth to a PXI Express system. The controller includes a 2.3 GHz AMD Turion 64 X2 dual-core processor, ExpressCard slot and Gigabit Ethernet. In addition, the 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 600 MB/s. The NI 8262 module provides a x4 cabled PCI Express link that can cable to the 3U HDD-8264, which includes twelve 250 GB SATA hard drives (3 TB), or the 1U HDD-8263, which includes four 250 GB SATA hard drives (1 TB).
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. 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.
