The new NI cRIO-908x systems feature an Intel® Core™ i7 dual-core 1.33 GHz processor and up to a Xilinx Spartan-6 FPGA to deliver the highest processing power of any CompactRIO product. The controllers can be configured with a Windows Embedded Standard 7 OS configuration, which gives you access to a broad ecosystem of Windows-based software and integrated graphics, or a real-time OS for reliable, deterministic performance. The systems provide a variety of high-performance peripheral connectivity including two Gigabit Ethernet ports, a MXI Express port, four USB ports, RS232 and RS485 serial ports and a new CPU eXpansion Module (CXM) that makes it possible to add custom connectivity and expansion to CompactRIO using industry standard protocols.

 

For high-volume and OEM applications, the new NI sbRIO-9605/06 devices are sized from less than 102.87 mm x 96.52 mm and offer greater customization and I/O support than previous versions. The devices feature a 400 MHz processor and Xilinx Spartan-6 FPGA to provide reliability and performance at a low price point. The devices also offer built-in peripherals such as RS232, CAN, USB and Ethernet. Additionally, the new devices feature a high-density and high-bandwidth connecter that gives you direct access to the FPGA and processor as well as the ability to add peripherals for further customization.

 

NI RIO technology combines LabVIEW with commercial off-the-shelf hardware to simplify development and shorten time to market when designing advanced control, monitoring and test systems. NI RIO hardware, which includes CompactRIO, NI Single-Board RIO, R Series boards and PXI-based NI FlexRIO, features an architecture with powerful floating-point processors, reconfigurable FPGAs and modular I/O. All NI RIO hardware components are programmed with LabVIEW to give you the ability to rapidly create custom timing, signal processing and control for I/O without requiring expertise in low-level hardware description languages or board-level design.

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.

 

Watch the video below to see how the NI PXIe-5605 compares against a traditional box instrument.
