Key product information and technical features.
NI PXI-7952R is an NI FlexRIO FPGA module for the PXI platform, not a standalone front-end measurement device. NI describes FlexRIO systems as modular combinations of an FPGA module and separate adapter modules, with the adapter connecting to the FPGA module through a card-edge connector. For catalog accuracy, PXI-7952R should therefore be classified as the primary FPGA carrier/module within the FlexRIO architecture rather than as a self-contained data acquisition module. https://www.ni.com/en/shop/electronic-test-instrumentation/flexrio/what-is-flexrio/components-of-a-flexrio-system-with-modular-i-o.html
The PXI-7952R uses a Xilinx Virtex-5 LX50 FPGA and includes 128 MB of onboard DRAM. NI also lists 7,200 user LUTs and 48 DSP48 slices for this model, while the FlexRIO FPGA Module Installation Guide and Specifications identifies 1,728 kbits of embedded block RAM for the PXI-7952R. These resources position the module for custom FPGA-based processing in measurement and I/O systems built around the FlexRIO platform. https://docs-be.ni.com/bundle/ni-flexrio-fpga-module-getting-started/raw/resource/enus/373047b.pdf https://www.ni.com/en/shop/electronic-test-instrumentation/flexrio/what-is-flexrio/components-of-a-flexrio-system-with-modular-i-o.html
Within the PXI-795xR family, NI specifies a 40 MHz default timebase and a PXI 10 MHz reference clock source (PXI_CLK10). These family-level timing details are documented in the official FlexRIO FPGA Module guide that includes the PXI-7952R. NI’s compatibility documentation also lists PXI-7952 among the FlexRIO FPGA modules used with compatible FlexRIO adapter modules, reinforcing that system functionality depends on the selected adapter rather than on the FPGA module alone. https://docs-be.ni.com/bundle/ni-flexrio-fpga-module-getting-started/raw/resource/enus/373047b.pdf https://www.ni.com/en/support/documentation/supplemental/17/ni-flexrio-adapter-and-ni-flexrio-fpga-module-compatibility.html
