RFmx模拟调制
RFmx模拟调制为测试应用提供模拟调制信号的生成和分析。
RFmx Analog Modulation是运行在RFmx解调器内的应用软件，它与RFmx Analog Modulation一起安装。该软件可扩展NI RF仪器对于模拟调制信号生成和分析的能力。您可以使用该软件，通过对频率/相位偏移、模拟调制深度、频率/相位偏差等的测量，分析AM、FM、PM和FM的立体声信号。此外，您可以通过应用去加重和音频滤波器来分析解调后的信号波形、频谱和失真。您可以通过交互式软件前面板进行和调试测量，利用随附的RFmx Waveform Creator创建和回放开放的、未锁定的波形，并利用性能优化的API加快自动测试。

Installation Instructions

Caution Before you install NI-RFmx Demod 2.4, 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 require that all the installed drivers have the same version for proper functionality because the NI-RFmx drivers use shared components that need to use the same version across all drivers. 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 Demod.NET examples require the NI-RFSG .NET Class Library. For these examples to build and run successfully, install NI-RFSG .NET Class Library before or after installing NI-RFmx Demod.

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:

• For more information about silent installations of individual NI products, refer to KB 4CJDP38M, Automating the Installation of a Single Installer.
• For more information about silent installations of NI products in a suite, such as NI Developer Suite, refer to KB 4GGGDQH0, How Do I Automate the Installation of a Suited Installer?.
• To determine what version of NI Installers your product contains, refer to KB 4CJDR18M, How Can I Determine the Type and Version of My NI Installer?.
  

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.
