NI just released the NI USRP-2920 and NI USRP-2921 instruments, which offer a new educational platform for true hands-on learning with real-world signals in university RF and communications labs. The new platform combines the NI universal software radio peripheral (USRP) hardware with LabVIEW and lab-ready course material.


The platform provides educators with an affordable solution that exposes students to practical application of abstract mathematical theories that have traditionally been taught using a theoretical, math-focused approach in which students derive formulas and build simulations. Students can now explore the link between abstract mathematical theory and practical implementation through hands-on experimentation with a working communications system.

NI has introduced a 14 GHz version of its NI PXIe-5665 high-performance RF vector signal analyzer (VSA), which delivers best in-class dynamic range and accuracy in a cost-effective PXI form factor.




The new VSA features industry-leading phase noise and dynamic range, regardless of form factor, including traditional rack-and-stack instruments. Because of its PXI platform, the VSA can deliver measurement speeds up to 20 times faster than box instruments and for less cost. Additionally, it takes advantage of multicore computing architectures and parallel programming capabilities through LabVIEW. It also offers peer-to-peer data streaming for signal processing and a flexible multiple input, multiple output (MIMO) architecture for phase-coherent measurements.


The VSA consists of the new NI PXIe-5605 downconverter, the NI PXIe-5653 local oscillator synthesizer and the NI PXIe-5622, a 150 MS/s intermediate frequency (IF) digitizer. This combination creates an ideal solution for spectrum and wideband vector signal analysis over a frequency range of 20 Hz to 14 GHz with analysis bandwidths up to 50 MHz. It features the industry’s best third-order intercept point at +24 dBm with an absolute amplitude accuracy of ±0.10 dB as well as an impressive error vector magnitude of 0.33 percent for a 256 QAM modulated signal. It also delivers an exceptionally low phase noise of -129 dBc/Hz at a 10 kHz offset at 800 MHz and an average noise level of -165 dBm/Hz.

The presentation slides for the 2010 NI Technical Symposium sessions are now available to download for your use as a training resource.


The NI Technical Symposium, a series of free day-long technical forums that highlight the latest NI technology for improving system performance and productivity, were presented in 27 U.S. and Canadian cities from September to December. The events were attended by nearly 3,000 engineers.


Each symposium delivered technical sessions, hands-on tutorials, and product demonstrations by NI experts. Topics included the following:

  • Optical and RF measurements
  • Advanced motion control
  • Real-time testing
  • Wireless sensor network programming
  • Best practices for LabVIEW development
