National Instruments 785172-01 PXI Coprocessor Module

The National Instruments 785172-01 (PXIe-7911) Coprocessor Module is designed to enhance PXI Express systems by integrating a Xilinx Kintex UltraScale KU035 FPGA. This module provides advanced signal processing capabilities that are programmable using NI LabVIEW or Xilinx Vivado. It supports high speed data streaming to and from other PXI modules. It leverages the x8 Gen 3 PCI Express architecture to achieve data rates of up to 7 GB/s without needing a host controller. This high throughput makes it ideal for real time processing that allows it to pair effectively with other PXI instruments such as vector signal transceivers to execute complex algorithms in real time.

The KU035 FPGA in this module 785172-01 offers a reconfigurable architecture with 203,128 LUTs and 1,700 DSP48 slices which allows for extensive signal processing operations that include complex mathematical functions. Its 19.0 Mb block RAM enables efficient memory usage for high performance applications. This reconfigurability makes it suitable for tasks that demand moderate signal processing power in fields like communications, control systems and automated test equipment. The NI 785172-01 supports multiple connection resources such as PXI triggers, PXI_CLK10, PXIe_DStarB/C and PXIe_Sync100. This ensures precise synchronization and coordination between modules in a PXI chassis. It features 60 DMA channels for high speed data transfer and uses an 80 MHz default timebase with an external reference option from the PXI Express 100 MHz timebase. This flexibility ensures compatibility with a wide range of high speed data acquisition and processing applications.

This coprocessor module integrates seamlessly with NI LabVIEW Instrument Design Libraries which offer pre built programming interfaces and documentation to streamline development. These libraries support the LabVIEW FPGA Module and enable users to program the FPGA for custom signal processing tasks. The 785172-01 module has dimensions of 18.8 cm × 12.9 cm and weighs 190 g. It operates within an ambient temperature range of 0 °C to 55 °C and can handle a relative humidity range of 10 % to 90 %. It is designed for indoor use and can operate at altitudes up to 2,000 meters. For storage, it tolerates temperatures between -40 °C and 71 °C and it is built to withstand shock up to 30 g peak and vibrations in various frequency ranges.
