NI's PXI Express responds to multi-core technology
01 June 2007
Responding to the increased use in multi-core technology, especially in PCs, National Instruments (www.ni.com) has introduced PXI Express high-speed instruments and an 18-slot PXI Express chassis.
Industry analyst, iSuppli (www.isuppli.com) reckons that quad-core microprocessor technology is likely to appear in the mid-market sector rapidly over the next two years and in half of the mainstream desktop systems by the end of 2009.
The PXI Express instruments are for use in signal intelligence, spectral monitoring, semiconductor chip characterisation and video test. They are, claims NI, the industry’s firstPXI Express high-speed instruments available and provide enhanced functionality of high-speed data recording and playback, using the PCI Express bus, which delivers up to 1Gbyte/sec of bi-directional streaming throughput on a x4 PCI Express link.
The modular instruments include the PXIe-5122 100 Msample/sec, 100MHz, dual-channel digitiser, which can be used to capture high-speed analogue signals on two simultaneous channels at 100Msample/sec with 14bit resolution. It can stream signals across the PCI Express bus at the full rate of 400Mbyte/sec to the PC memory or the hard drive, or both if required. Digital waveforms can be streamed, at 200Mbyte/sec, to and from the PXIe-5122 using the PXIe-6537 and PXIe-6536 50MHz and 25MHz, 32-channel, digital I/O modules.
The PXI-1065 18-slot chassis offers up to 1Gbyte/slot dedicated bandwidth and both PXI and PXI Express slots. It complements the company’s PXIe-1062 eight-slot chassis to address the high-density required of PXI Express systems. The combination of PXI and PXI Express hybrid slots can be used for existing PXI modules and high-bandwidth PXI Express modules.
The modules can be used with the company’s LabVIEW, LabVIEW SignalExpress interactive measurement software and TestStand test management software.
