NI-RFmx SpecAn 2.3 includes the following new features:
Caution Before you install NI-RFmx SpecAn 2.5, ensure that you have uninstalled all related NI-RFmx 1.0 products.
Caution If you are using only RFmx LabVIEW Runtime products, NI recommends uninstalling all the RFmx Runtime products before installing a newer version of RFmx Runtime products.
NI-RFmx drivers requires that all the installed driver versions remain the same for proper functionality. This requirement is because NI-RFmx drivers share components. If driver incompatibilities exist, they are reported through a dialog box after installation. You can also use the Version Compatibility Checker utility to manually check for version incompatibilities. Refer to the Installed Software, Documentation, and Examples section for more information about the installed location of the Version Compatibility Checker utility.
Note Some of the installed NI-RFmx SpecAn .NET examples require NI-RFSA .NET Class Libraries or NI-RFSG .NET Class Libraries. For these examples to build and run successfully, install NI-RFSA .NET Class Libraries or NI-RFSG .NET Class Libraries before or after installing NI-RFmx SpecAn.
The Noise Figure measurement requires license activation. To evaluate or activate the Noise Figure license, you must install the Noise Figure license, which is a separate installer from the RFmx SpecAn installer. If you install the Noise Figure license but do not activate it, you will have 30 days from the first time you use the measurement to evaluate it.
Device-specific information about these modules is included in the NI RF Vector Signal Analyzers Help.
Device-specific information about these modules is included in the NI RF Vector Signal Transceivers Help.
NI-RFmx SpecAn 2.5 supports the following operating systems:
Note In 2016, NI-RFmx SpecAn dropped support for Microsoft Windows 7 RTM (with no service pack), Windows Vista, Windows XP, and Windows Server 2003. NI-RFmx SpecAn 2.5 will not install or run on an unsupported OS. You cannot deploy or distribute applications that use NI-RFmx SpecAn 2.5 to an unsupported OS. Additionally, after installing NI-RFmx SpecAn 2.5, 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.
For more information about the changes to our OS support for 2016, refer to KB 79UC78LS, Why Does my LabVIEW, LabWindows/CVI, Measurement Studio, or TestStand Built Installer Fail on Windows XP/Vista and Server 2003?.
1 NI software installs VC2015 Runtime and .NET 4.6.2. 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-RFmx SpecAn 2.5 does not support Windows Server non-R2 editions.
NI recommends that you have the most recent service pack for your operating system installed.
*Depending on the amount of data acquired and/or processed, a larger amount of memory may be required.
Note For better responsiveness of the NI-RFmx Soft Front Panel on a remote desktop, National Instruments recommends changing the remote desktop connection colors setting to be 16-bit color depth.
Note You should install ADEs, such as NI LabVIEW, NI LabWindows/CVI, or Microsoft Visual Studio®, before installing NI-RFmx SpecAn. To add support for ADEs installed after installing NI-RFmx SpecAn, modify your NI-RFmx SpecAn installation or launch the NI-RFmx SpecAn installer again.
Note NI-RFmx SpecAn does not operate correctly without the service packs and patches previously mentioned installed.

When developing memory intensive applications, you may encounter memory limits as 32-bit Windows applications only utilize 2 GB of memory by default. To expand the amount of memory an application can utilize, you can configure the executable to be large address aware to gain access to up to 3 GB of memory on a 32-bit Windows operating system and up to 4 GB of memory on a 64-bit Windows operating system.
For more information, refer to Memory Limits for Windows and Windows Server Releases on the Microsoft website.
|Note LabVIEW 8.5 and later are large address aware. For more information, refer to How Much Memory can LabVIEW 32-bit or 64-bit Use?.|
In TestStand 2013 and later, the Large Address Aware flag is enabled by default for the TestStand Sequence Editor and TestStand User Interfaces. For more information, refer to Using the Large Address Aware Flag With TestStand Applications.
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.
