PXI Express instruments offer faster data streaming

Eric Starkloff, National Instruments Director of Test Product Marketing, comments: "PXI Express builds on commercial PCI Express technology to expand the applications served by the multivendor PXI standard. The addition of high-speed data streaming capability to PXI, while preserving compatibility to the more than 1200 existing PXI modules from more than 70 vendors, has made PXI a leading platform for modular instrumentation."

The new PXI Express instruments add to the wide range of PXI mixed-signal products from NI that include high-speed digitisers/oscilloscopes, high-speed digital I/O, baseband and RF analysers and signal generators. The new instruments offer the enhanced functionality of high-speed data recording and playback using the latest industry-standard bus, PCI Express, which delivers up to 1GB/s of bidirectional streaming throughput on a x4 PCI Express link. With the NI PXIe-5122 digitiser (based on a x4 PXI Express link), for example, engineers can capture high-speed analogue signals on two simultaneous channels at 100MS/s with 14-bit resolution and stream the signals across the PCI Express bus at the digitiser's full rate of 400MB/s to the PC memory and/or hard disk. Engineers can also use the NI PXIe-6536/37 digital I/O modules (based on a x1 PXI Express link) to stream digital waveforms to and from the module at the full 200MB/s data rate.

The NI PXIe-1065 18-slot chassis complements the existing NI PXIe-1062 eight-slot chassis to address higher-channel-density PXI Express-based systems. The new chassis includes a combination of PXI and PXI Express hybrid slots to accept a mix of both existing PXI modules and high-bandwidth PXI Express modules.

All of the new products integrate with a variety of software including the NI LabVIEW graphical development environment, LabVIEW SignalExpress interactive measurement software and NI TestStand test management software.
