Overview

The PXI platform, because it is based on the high-bandwidth PCI and PCI Express buses, enables instruments to stream data to and from RAID-0 (striped) hard drive arrays at high sustained rates. National Instruments Noise Mapping systems combine National Instruments Sound and Vibration hardware with RAID-0 hard drive arrays for high-speed, long-duration recording and analysis.

The PXI Platform

National Instruments High Channel Count Noise Mapping systems are based on the open, industry-standard PXI platform. PXI provides the following benefits for Noise mapping applications:

  • PC-based platform leveraging low-cost commercial PC components
  • High-bandwidth PCI and PCI Express buses
  • Over 1,500 products available from the more than 70 PXI vendors
  • Extensive breadth of I/O modules
  • Compatibility with CompactPCI (cPCI) modules
  • Rugged Eurocard form factor with a small system footprint
  • Virtually unlimited channel expansion capabilities
  • Tight multi-module and multi-chassis synchronization
  • Internal and external clocking and triggering
  • Synchronization with external systems and devices
  • IRIG and GPS timestamping and synchronization

System Architecture

National Instruments High Channel Count Noise Mapping systems consist of a PXI chassis containing up to 17 NI PXI-449x DSA boards for high channel count or up to 17 NI PXI-446x DSA boards for high speed acquisition. Then systems are controlled by a 3.0 GHz rack mount PXI controller running Windows and a development environment such as National Instruments LabVIEW. The rackmount controller comes with an onboard RAID0 set-up for either 2x250GB or 2x400GB.  The onboard RAID0 is capable of storing data at around 100 MB/s.  This feature enables continuous streaming at high rates for hours.  Here is a look at the PXI-8351 rackmount controller which will be cabled through MXI-Express to the PXI chassis full of DSA hardware:
