The new R Series devices are equipped with high-performance Kintex-7 FPGAs, which offer improved optimization capabilities to achieve faster code execution and more LabVIEW code capacity than previous-generation R Series devices. The new Kintex-7 FPGAs are ideally suited for USB R Series devices. This device family has the capacity and performance of previous-generation high-end FPGAs but at half the power. The impressive reduction in power has resulted in the ability to pack up to 10 times the digital signal processing (DSP) capability per device as the previous generation of R Series devices. With this increase in logic and DSP resources, you can implement more complex algorithms with more extensive use of signal processing and real-time analysis and address the growing I/O data rates and complexity of today’s applications. To learn more about Kintex-7 FPGAs, see [Advantages of Xilinx 7 Series FPGA Modules].
In addition, the new NI USB-785xR devices can sample up to 1 M/s on all eight analog input channels with 16-bit resolution and selectable gain resolution of ±10 V, ±5 V, ±2 V, and ±1 V. With FPGA-based parallel execution, multiple control loops do not have to compete for processor bandwidth. Faster analog input rates also improve analog triggering precision and frequency measurement capabilities. The new NI USB-785xR devices also natively support fixed-point I/O, which allows you to work directly with engineering units in the FPGA.
Finally, the new R Series devices feature faster digital I/O channels that can toggle at speeds up to 80 MHz. Furthermore, you can select the voltage levels of the digital I/O lines directly from LabVIEW FPGA. The available logic levels are 3.3 V, 2.5 V, 1.8 V, 1.5 V, and 1.2 V.
