If you are using the NI-FGEN .NET Class Library, the .NET Framework 4.0 (minimum) is required. The NI-FGEN .NET Class Library can be used with the Visual C# or Visual Basic .NET programming languages in any Visual Studio version that can target the .NET Framework 4.0 or the .NET Framework 4.5.
To use the .NET API, you must select the .NET Framework 4.0 Languages Support or the .NET Framework 4.5 Languages Support packages in the NI-FGEN installer to install the the .NET class libraries in addition to the NI device driver. For information about versions of the .NET Framework and the drivers each supports, as well as the download location of the installer files, refer to National Instruments .NET Driver Support.
Download the NI-FGEN installer from ni.com/downloads. NI software includes NI Package Manager to handle the installation. Refer to the NI Package Manager Manual for more information about installing, removing, and upgrading NI software using NI Package Manager.
When installing NI-FGEN, the "NI-FGEN Support for LabVIEW" package will be recommended if you have already installed LabVIEW 2022 or later and installs to the LVAddons directory. This package supports applications using NI-FGEN with LabVIEW 2022 or later.

NI-FGEN no longer installs IVI Compliance Package (ICP). NI-FGEN supports IVI configuration and runtime, but no longer installs the following IVI components:
To use these features, you must install ICP separately. ICP is included in the Software Platform Bundle media. A stand-alone web distribution is available from ni.com/downloads.
NI-FGEN driver when used with NI Linux® Real-Time will not support Onboard Signal Processing. This feature remains supported on Windows.
The PXIe-5442, PXIe-5450, and PXIe-5451 have upgradeable device firmware. It is highly encouraged and may be required that you upgrade the firmware on these devices; newer firmware contains new features and important bug fixes. To update the firmware, run the Firmware Updater application for your device (54xxFirmwareUpdater_X.Y.Z.exe, where 54xx is the name of the device and X.Y.Z is the firmware version) that is installed in the Program Files (x86)\National Instruments\NI-FGEN\ directory. This application upgrades your firmware to the latest available version that works with this driver. After the application runs, you are required to power down your computer and PXI Express chassis to complete the firmware update.
The NI-FGEN Soft Front Panel has been replaced by InstrumentStudio, which is automatically installed when you install the NI-FGEN driver. You can access InstrumentStudio in one of the following ways:
Note The deprecated NI-FGEN Soft Front Panel remains available for download. Visit Legacy Soft Front Panels for NI-FGEN for more information.
Refer to the NI Signal Generators Help, accessible from Start»All Programs»National Instruments»NI-FGEN»NI-FGEN Documentation, for information about NI-FGEN.
You can access all the installed NI-FGEN examples for LabVIEW, LabWindows/CVI, C, and .NET at Start»All Programs»National Instruments»NI-FGEN»NI-FGEN Examples and online at ni.com/examples. Examples also are available online that demonstrate integrating NI waveform generators with NI toolkit software including the Modulation Toolkit. Refer to ni.com/examples for these examples and for more information.
Select Help»Find Examples from LabVIEW or LabWindows/CVI to launch the NI Example Finder. LabVIEW examples for NI-FGEN are located in the LabVIEW XXXX\examples\instr\niFgen directory. You can modify an example VI to fit an application, or you can copy and paste from one or more examples into a VI that you create.
The NI Example Finder offers two ways to access all installed LabVIEW example VIs and their descriptions:
You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes.
If the NI product you are installing uses Microsoft .NET 4.0, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.0 separately before you install NI software.
For more information about automating the installation of NI products, refer to the following KnowledgeBase articles:
Microsoft Windows 10 is the latest version of the Windows operating system and features significant changes compared to previous versions. Windows 10 introduces several new capabilities and also combines features from both Windows 7 and Windows 8. For more information about NI support for Windows 10, visit ni.com/windows10.
