  • Capture real-world impairments of off-the-air signals
  • Continuously record up to 20 MHz of instantaneous bandwidth for more than five hours
  • Play back up to 100 MHz of instantaneous bandwidth
  • Record and play back FM, GPS, DVB, ATSC, and more
The high-bandwidth PCI and PCI Express buses enable 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 test receivers with real-world signals that are captured with an antenna. As a result, you can observe how receivers are able to adapt to impairments common in their deployment environments.
