NI PCIe-7841R, PCIe-7842R, PCIe-7851R, PCIe-7852R Multifunction RIO Boards
National Instruments introduced the NI PCIe-7841R, NI PCIe-7842R, NI PCIe-7851R, and NI PCIe-7852R R Series multifunction RIO boards for PCI Express. The boards give engineers and scientists the benefits of field-programmable gate array (FPGA) technology in a widely adopted form factor. The boards combines a Xilinx Virtex-5 FPGA, eight analog inputs, eight analog outputs, and 96 digital I/O lines on a single board. Using the NI LabVIEW FPGA Module, engineers and scientists can program the onboard FPGA to create custom measurement hardware for custom data acquisition, high-speed control, digital communications protocols, sensor simulation, hardware-in-the-loop, and signal processing applications.
The NI R Series boards give engineers and scientists the high-speed processing power provided by FPGAs. The boards are equipped with either a Virtex-5 LX30 or Virtex-5 LX50 FPGA, both of which offer increased performance with more efficient logic resource use and faster logic execution rates. R Series boards with Virtex-5 FPGAs also deliver twice the processing power of previous generation Virtex-II-equipped R Series boards at the same price.
Engineers and scientists with limited or no hardware design experience easily can program the FPGA on R Series boards using the LabVIEW FPGA Module, which abstracts the VHDL code used to configure the FPGA. LabVIEW also provides pre-built function blocks and other code optimization techniques to expedite application development. For engineers and scientists that program in C, the recently released NI C Interface to LabVIEW FPGA makes it possible for them to integrate new or existing C applications with NI FPGA hardware programmed with the LabVIEW FPGA Module.
With integrated FPGA technology, R Series multifunction RIO boards can be configured to meet numerous application needs such as custom data acquisition, sensor simulation and high-performance control. With the wide availability and decreasing costs of standard desktop PCs, engineers, scientists and OEMs can combine a PC and a new PCI Express R Series board to create powerful, cost-optimized custom hardware systems including a high-speed control system with eight 750 kHz proportional integral derivative (PID) loops running in parallel, a custom digital protocol interface for communicating with or characterizing a device under test, or a sensor simulation system for hardware-in-the-loop testing.
Engineers and scientists can achieve 16-bit analog input sampling rates up to 200 kS/s per channel with the NI PCIe-7841R and NI PCIe-7842R and sampling rates up to 750 kS/s per channel with the NI PCIe-7851R and NI PCIe-7852R. The new R Series boards take advantage of dedicated bandwidth per device for reliable, high-speed data streaming. The boards also offer DMA channels for streaming data to and from the FPGA at more than 100 MB/s per device without significantly impacting processor resources.
