NI-RFSG Instrument Driver FPGA Extensions

    Last Modified: December 19, 2018

    NI-RFSG instrument driver FPGA extensions for VSTs enable you to use precompiled FPGA bitfiles to customize the behavior of the VST FPGA while maintaining the functionality of the NI-RFSG instrument driver.

    Before you begin using NI-RFSG instrument driver FPGA extensions, you must install NI-RFSG and LabVIEW NXG. You must also download a precompiled bitfile to use NI-RFSG instrument driver FPGA extensions. Visit and enter the Info Code ex6h8h, then select your hardware, and browse the download page to download an NI-RFSG instrument driver FPGA extensions precompiled FPGA bitfile.


    Certain NI-RFSG instrument driver FPGA extensions might require you to install the instrument design libraries. Refer to the installation requirements of individual NI-RFSG instrument driver FPGA extensions located on the download page for more information.

    The precompiled bitfiles are included in examples that illustrate how to use the precompiled bitfiles. These examples contain three parts—a precompiled bitfile featuring application-specific IP, a host-based example that uses NI-RFSA, NI-RFSG, or both, and IP dependencies, such as source code. These examples are distributed through the VI Package Manager, which installs with LabVIEW NXG.

    When you install NI-RFSG, model-specific folders for your VST module are created in the following location:
    • Windows 10/8.1/7: Users\Public\Documents\National Instruments\FPGA Extensions Bitfiles

    The instrument driver searches for precompiled bitfiles in these model-specific folders. For the instrument driver to recognize your precompiled bitfile, ensure that the precompiled bitfile is located in the model-specific folder that corresponds to your hardware.
