Consider NI PXIe-PCIe8381 over the NI PXIe-PCIe8371/2 as it provides 4X better bandwith at similar price.
With the National Instruments PXIe-PCIe837x kits, you can control PXI Express and CompactPCI Express systems from a x4 (“by four”) or higher PCI Express slot in your desktop or server PC through a fully transparent, high-bandwidth cabled PCI Express link. The NI PXIe-PCIe837x kits consist of a PCI Express board in the PC, connected via a x4 MXI-Express cable to a PXI Express module in slot 1 of a PXI Express chassis. The PCI Express board is available in two configurations. The NI PXIe-PCIe8371 kit includes a PCI Express board with one x4 PCI Express link that provides up to 798 MB/s of sustained throughput when cabled to a single PXI Express chassis. In the NI PXIe-PCIe8372 kit, the PCI Express board has two x4 PCI Express links, each of which can be cabled to a PXI Express chassis to provide up to a total of 832 MB/s of sustained throughput. The NI PXIe-8370 module, used in both kits, implements a PCI Express-to-PCI Express switch. To configure a complete PXI Express system based on a MXI-Express kit, visit ni.com/pxiadvisor.
