National Instruments Extends PXI Software-Defined Instrumentation
National Instruments (Austin, Texas) introduced four new adapter modules for its NI FlexRIO product family, which provides FPGA-based reconfigurable I/O (RIO) for PXI systems, using the LabVIEW FPGA Module software. The user-configurable NI FlexRIO product family takes advantage of industry-leading PXI hardware and software integration to give engineers a commercial off-the-shelf (COTS) solution that is specifically designed to more easily implement field-programmable gate array (FPGA) technology for advanced automated test and measurement systems. NI FlexRIO solutions combine two distinct hardware components, a programmable PXI or PXI Express-based FPGA module and an I/O adapter module. The four new NI FlexRIO adapter modules are ideal for real-time measurements, nondestructive test (NDT) and ultrasound applications, communications systems and scientific research.
"Using NI FlexRIO, we designed an advanced ultrasound instrument in less than three months," said Dave Lines, chief engineer at Diagnostic Sonar, a leading developer of ultrasonic systems for industrial and medical applications. "Because of the tight integration of NI FlexRIO hardware and LabVIEW FPGA software, our entire development process, including architecture specification, FPGA coding and real-time 3D display creation, was significantly shortened, and we were able to create an instrument that was much more customizable and scalable compared to existing systems."
The new NI FlexRIO adapter modules reflect the continued investment of National Instruments in FPGA-based RIO and expand the company's selection of PXI modular instrumentation with user-configurable FPGAs. Designed for test and measurement applications that require real-time performance and hardware signal processing, the new modules include the following unique capabilities:
-- NI 5761: four-channel, 14-bit, 250 MS/s broadband high-performance digitizer adapter module designed to meet a wide range of signal processing application needs including communications system design, intermediate frequency (IF) acquisition, multiple input, multiple output (MIMO), radar and scientific research
-- NI 5751: 16-channel, 50 MS/s, 14-bit digitizer adapter module for test and measurement in areas such as experimental physics, NDT and medical imaging
