API Overview
IVI and LabVIEW drivers are not part of the M8920A, and are
installed seperately.
IVI Drivers
Keysight's IVI drivers simplify the creation and maintenance of instrument control
applications in a variety of development environments; they allow programmatic
control of instrumentation while providing a greater degree of instrument
interchangeability and code reuse. IVI drivers currently come in two basic types: IVI-
COM and IVI-C. Although the functionality offered by both types of drivers is often
very similar, the fundamental differences in interface technology results in a very
different end-user experience. The IVI drivers support compiling application programs
for 32- or 64-bit platforms.
Supported ADEs (application development environments) Arguably the most
important consideration in comparing IVI-COM and IVI-C drivers is the end user
experience in various ADEs. Since IVI-COM drivers are based on Microsoft COM
technology, it's not surprising that IVI-COM drivers offer the richest user experience in
Microsoft ADEs. Users working in Visual C++, Visual C#, Visual Basic.NET, and Visual
Basic 6 enjoy a host of features, such as object browsers, IntelliSense, and context-
sensitive help.
When you install the product software, the IVI driver files are installed in the standard
IVI Foundation directories (for example, C:\Program Files\IVI
Foundation\IVI\Drivers\). Example programs are provided to demonstrate most driver
functionality (for example, C:\Program Files\IVI Foundation\IVI\Drivers\AgM939
Examples). The reference material for the driver functions (a Microsoft HTML Help
.chm file) is installed with the IVI driver and is available for Microsoft Visual Studio's
IntelliSense context linking. In addition, you can directly access the .chm file
(AgM9391.chm from this Start menu location: Start > All Programs > Keysight
Instrument Drivers > IVI-COM-C Drivers > AgM9391 VSA > AgM9391 IVI Driver Help.

LabVIEW Drivers
In addition to the IVI drivers, Keysight provides a LabVIEW driver that includes all the
functionality of the IVI-C driver. When you install the product software, the LabVIEW
driver is installed to each LabVIEW instr.lib directory for each version of LabVIEW you
have on your computer (for example, C:\Program Files (x86)\National
Instruments\<LabVIEW version>\instr.lib\<Keysight product model>). If you install
LabVIEW drivers before you install LabVIEW itself, drivers will be installed in the
Keysight directory instead of the National Instruments directory (for example,
C:\Program Files (x86)\Keysight\<Keysight product model>\LabVIEW
Driver\<LabVIEW version>\...). Example programs are provided to demonstrate most
