New Features

NI-RFmx SpecAn 2.2 includes the following new features:


  • Support for LabVIEW 2016 (32-bit and 64-bit)
  • Addition of noise figure (NF) measurement using Y-Factor and Cold Source methods.
  • Addition of intermodulation (IM) distortion measurements.
  • Support for noise compensation in Spectrum measurement.
  • Support for the linear LUT type in DPD.

  • Support for LabVIEW 2015 (32-bit and 64-bit)

NI-RFmx SpecAn 1.2 includes the following new features:


  • Support for NI 5668R
  • Addition of AMPM and DPD measurements

NI-RFmx SpecAn 1.1 includes support for C, LabWindows™/CVI™, and .NET.


Installation Instructions

Caution  Before you install NI-RFmx SpecAn 2.2, 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.


Activation Instructions for NI-RFmx Noise Figure License

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.

Increasing Available Memory For Your Application

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.


Automating the Installation of NI Products

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:


Using NI Software with Microsoft Windows 10

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.


Using NI Software with Microsoft Windows 8.1

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.
