RF Record and Playback

Because the PXI platform is based on the high-bandwidth PCI and PCI Express buses, it enables instruments to stream data to and from RAID 0 (striped) hard drive arrays at high sustained rates. National Instruments RF record and playback systems combine PXI RF signal analyzers and RF signal generators with RAID arrays for high-speed, long-duration recording and playback.

With the ability to generate or acquire terabytes of continuous data, PXI instruments can help you implement applications previously possible only with custom hardware, such as:

  • Spectrum monitoring
  • Packet sniffing
  • Wireless receiver design, validation, and verification
  • Digital Video Broadcasting BER tests

Featured RF Record and Playback System

A complete system includes a PXI chassis and controller with an NI PXI-5661 vector signal analyzer and an NI PXIe-5672 vector signal generator. The external hard drive array can hold terabytes of data, enabling hours of continuous streaming.
