NI PXI-7841R

National Instruments has released four R Series I/O modules for the PXI platform that are equipped with Xilinx Virtex-5 FPGAs. The NI PXI-7841R, PXI-7842R, PXI-7851R and PXI-7852R modules feature eight analog inputs, eight analog outputs and 96 digital I/O lines as well as analog input rates that are more than 3.5x faster than previously released R Series devices. These new modules provide engineers and scientists with commercial off-the-shelf hardware that can be graphically programmed with the NI LabVIEW FPGA Module to perform custom onboard processing for inline data analysis and deterministic I/O control for applications that require specialized timing and triggering.

"The unprecedented flexibility of FPGA technology makes FPGAs ideal for both complex embedded system design and high-performance data acquisition and test applications," said James Truchard, NI president, CEO and cofounder. "With our continued investment in FPGA technology including the new R Series devices and the LabVIEW FPGA Module, National Instruments is giving test engineers and embedded programmers alike a tightly integrated platform that makes it easy for them to take advantage of the incredible potential of FPGAs."

Engineers and scientists can achieve 16bit analog input sampling rates up to 200KSps/ch with the PXI-7841R and PXI-7842R and sampling rates up to 750KSps/ch with the PXI-7851R and PXI-7852R. Additionally, the new R Series modules are equipped with either a Virtex-5 LX30 or Virtex-5 LX50 FPGA, which deliver improved optimization capabilities that provide faster code execution and increased LabVIEW code capacity than previous R Series devices.

Virtex-5 FPGAs feature a six-input LUT architecture for substantially improved resource utilization as well as DSP slices that make it possible for users to implement more complex DSP at faster rates. The combination of high-speed I/O and Virtex-5 FPGAs on these new R Series modules makes them ideal for high-performance processing and control applications in industries such as automotive, life science and aerospace/defense.

With PXI instrumentation, engineers and scientists can customize their applications by choosing from over 1,500 measurement, signal generation, RF, power and switch modules and configuring their instruments in software to achieve the functionality they need. The R Series modules extend this customization even further by incorporating a Virtex-5 FPGA that can be programmed with the LabVIEW FPGA Module to create user-defined hardware. The LabVIEW FPGA Module simplifies the task of customizing hardware through easy-to-use graphical programming that abstracts VHDL code used to configure the FPGA. LabVIEW also offers pre-built function blocks and other code optimization techniques that expedite application development. This graphical system design approach helps engineers and scientists design, prototype, test and deploy custom measurement and embedded design applications faster and more cost-efficiently than the traditional approach to custom hardware design.

Pricing for the new devices vary on model. The NI PXI-7841R is priced from $2,799, NI PXI-7842R is priced from $3,599, NI PXI-7851R is priced from $3,399 and NI PXI-7852R is priced from $4,199.
