PXIe-7971

The PXIe‑7971 provides flexible, customizable I/O for LabVIEW FPGA. It includes 136 single-ended I/O lines configurable as 68 differential pairs. You can pair the PXIe‑7971 with FlexRIO adapter modules that offer high-performance analog and digital I/O. Together, the two modules create a reconfigurable instrument that you can program with LabVIEW FPGA software. The PXIe‑7971 supports peer‑to‑peer streaming, which directly transfers data among multiple FPGA modules or select PXI Express modules without sending data to the host processor. With this feature, you can add FPGA capabilities to high-performance NI digitizers with NIST‑traceable calibration or expand your FPGA algorithms across multiple FPGAs for computationally demanding applications.
