                                        \nThe PXIe-7972 provides 840 DSP slices<\/strong> for implementing signal-processing functions.\n<\/p>\n

                                        How much block RAM does the PXIe-7972 have?<\/h4>\n

                                        \nThe PXIe-7972 provides 16,020 kbit of FPGA block RAM<\/strong>.\n<\/p>\n

                                        Does the PXIe-7972 support peer-to-peer streaming?<\/h4>\n

                                        \nYes. Peer-to-peer streaming allows compatible PXI Express and FPGA modules to transfer data directly without routing every transfer through the host processor.\n<\/p>\n

                                        Does the PXIe-7972 require a FlexRIO adapter module?<\/h4>\n

                                        \nFor applications requiring application-specific external analog or digital I\/O, the PXIe-7972 is paired with a compatible FlexRIO adapter module. The FPGA module and adapter together form a reconfigurable instrument.\n<\/p>\n

                                        Does the PXIe-7972 support LabVIEW FPGA?<\/h4>\n

                                        \nYes. LabVIEW FPGA is used to develop user-defined FPGA functionality for the PXIe-7972.\n<\/p>\n

                                        What is the difference between PXIe-7972 and PXIe-7971?<\/h4>\n

                                        \nBoth use the Kintex-7 K325T FPGA and provide similar FPGA logic resources. A major difference is memory: the PXIe-7972 provides 2 \u0413\u0411 \u041e\u0417\u0423<\/strong>, while the PXIe-7971 does not provide onboard DRAM.\n<\/p>\n

                                        What is the difference between PXIe-7972 and PXIe-7976?<\/h4>\n

                                        \nThe PXIe-7976 uses a larger Kintex-7 K410T FPGA with more FPGA slices, DSP slices, and block RAM. Both provide 2 GB DRAM, but the PXIe-7976 is better suited to FPGA applications requiring greater programmable processing resources.\n<\/p>\n

                                        Can the PXIe-7972 be used for hardware-in-the-loop testing?<\/h4>\n

                                        \nYes. The programmable FPGA and deterministic hardware execution make the PXIe-7972 suitable for compatible HIL simulation and control applications.\n<\/p>\n

                                        What should I check before purchasing a PXIe-7972?<\/h4>\n

                                        \nBefore purchasing a PXIe-7972, verify the required FPGA resources, FlexRIO adapter module compatibility, PXI Express chassis slot compatibility, I\/O requirements, data throughput, DRAM requirements, peer-to-peer streaming requirements, LabVIEW FPGA version, FlexRIO driver compatibility, and FPGA development environment.\n<\/p>\n

                                        \u0417\u0430\u043a\u043b\u044e\u0447\u0435\u043d\u0438\u0435<\/h3>\n

                                        \n\u0417\u0435\u043c\u043b\u044f NI PXIe-7972 FlexRIO FPGA Module<\/strong> combines a Xilinx Kintex-7 325T FPGA, 50,950 FPGA slices, 840 DSP slices, 16,020 kbit block RAM, 2 GB onboard DRAM, 1.7 GB\/s data bandwidth, and 136 configurable FPGA I\/O lines. With LabVIEW FPGA programmability, peer-to-peer streaming, PXI timing resources, and compatibility with FlexRIO adapter modules, the PXIe-7972 provides a flexible platform for custom instrumentation, high-speed data acquisition, digital protocol communication, real-time signal processing, HIL testing, and advanced automated test systems.<\/p>","protected":false},"excerpt":{"rendered":"
