** The NI-USRP instrument driver supports UBX, CBX, CBX-120, WBX, WBX-120, SBX, SBX-120, and XCVR2450 daughterboards. Other daughterboards may also be compatible, but they have not been tested.
Device-specific information about these modules is included in the NI-USRP Help.
1 NI software installs VC2015 Runtime and .NET 4.6.1. Windows 8.1 and Windows Server 2012 R2 require Microsoft updates to support these items. Refer to Microsoft KB2919442 and KB2919355 for more information about how to install these updates.
2 NI software is signed with a SHA-256 certificate. Windows 7 SP1, Windows Embedded Standard 7 SP1, and Windows Server 2008 R2 SP1 require Microsoft updates to support SHA-256. Refer to Microsoft KB3033929 for more information about how to install this security update.
Note NI-USRP 16.0 and later does not support Windows Server non-R2 editions.
NI recommends that you have the most recent service pack for your operating system installed.
Note You should install ADEs, such as NI LabVIEW or LabVIEW Communications System Design software, before installing NI-USRP 16.0. To add support for ADEs installed after installing NI-USRP, modify your NI-USRP installation or launch the NI-USRP installer again.

NI-USRP includes several example applications for LabVIEW. These examples serve as interactive tools, programming models, and as building blocks in your own applications. NI-USRP includes examples for getting started and other software-defined radio (SDR) functionality. You can access the NI-USRP examples from the following locations:
Note The NI Example Finder does not include NI-USRP examples.
USRP RIO includes several sample projects for LabVIEW. These sample projects serve as starting points to build a USRP RIO streaming application. To access the LabVIEW sample project from the Create Project dialog, select Sample Projects in the left pane and navigate to the NI-USRP Simple Streaming project.
You can access additional examples from the Code Sharing Community at ni.com/usrp.
With this release, NI-USRP drops support for Microsoft Windows 7 RTM (with no service pack), Windows Vista, Windows XP, and Windows Server 2003. NI-USRP 16.0 and later will not install or run on an unsupported OS. You cannot deploy or distribute applications that use NI-USRP 16.0 to an unsupported OS. Additionally, after installing NI-USRP 16.0, you cannot use any installers built on this computer with any version of LabVIEW, LabWindows™/CVI™, NI TestStand™, or Measurement Studio on an unsupported OS.

NI-USRP versions are now aligned with the versions of major NI application software products. This alignment gives you information about the year the driver was released and the most recent software version the driver was designed to work with. Driver versions now start with a two-digit year indicator: <ProductName><Year-BasedVersion>. For example, NI-USRP 16.0 is the version released with LabVIEW 2016. The last version released under the old numbering scheme is NI-USRP 1.3. The first version released under the new numbering scheme is NI-USRP 14.0.
For Windows 7, complete the following steps:
For Windows 10/8.1, complete the following steps:
As part of the NI-USRP 16.0 installation, the following software is installed. To completely remove the NI-USRP 16.0 installation from your system, you must also remove all of the following packages:
Caution Several of the software packages listed above are shared with other NI software packages. If you attempt to remove a piece of software that something else is dependent on, a message launches to warn you about the software dependencies. You can choose to either uninstall all of the software or to leave the shared software installed. If you choose to uninstall the shared software, some of your other NI software may no longer function correctly.
Note Do not attempt to uninstall by manually deleting files.
USRP-294x/295x devices support both 1G Ethernet and 10G Ethernet using the connectors on the device back panel. With the default FPGA image, port 0 is designated for 1G, and port 1 is designated for 10G.
Note The FPGA cannot be modified when the USRP-294x/295x device is connected through Ethernet.
You can access the software and documentation known issues list online. Refer to the NI-USRP 16.0 Known Issues at ni.com/info and enter the Info Code exr6ia for an up-to-date list of known issues in NI-USRP 16.0.

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. However, starting with the August 2012 releases (products using NI Installers version 3.1 or later), you may need to perform additional steps before or during a silent installation of NI software.
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.
When you install National Instruments software on Microsoft Windows 8.1, you will notice a few additional tiles in the Apps view, including shortcuts to NI application software products such as NI LabVIEW, Measurement & Automation Explorer (NI MAX), and NI Launcher. For more information about NI support for Windows 8.1, visit ni.com/windows8.
