What is an IVI-COM driver?

IVI drivers are available in two flavors: IVI-C and IVI-COM. IVI-C drivers are

developed for use in ANSI C development environments. IVI-COM drivers are

developed for use in development environments that support the Component

Object Model (COM).

IVI-COM drivers are used in the typical Windows-based PC ADEs like Visual

C# and Visual Basic .NET, but also including Agilent VEE, NI LabVIEW, NI

TestStand, MATLAB, and other ADEs. Agilent Technologies recommends

IVI-COM libraries based on the ease of integration into these advanced ADEs.

What is Visual C#?

Visual C# (abbreviated VC#, pronounced C-sharp) is Microsoft’s

implementation

of the C# programming language. Because Microsoft wrote the C# programming

language specification and their implementation is the most popular, it is safe to

assume that when someone is talking about C# they are also talking about VC#.

VC# includes a graphical development environment and supports very rapid

development of Windows

-based applications.

C# is a simple, modern, general-purpose, object-oriented programming language.

It has been developed within the .NET initiative and is compatible with the 3.5

framework. C# is ideally suited to controlling instruments when paired with IVI

drivers.

What is VISA-COM?

Virtual Instrument Software Architecture (VISA) libraries are used for

communicating with devices over GPIB, USB, and a variety of other buses.

VISA libraries are managed by the IVI Foundation (http://ivifoundation.org/)

and are available in two flavours: VISA-C and VISA-COM. VISA-C libraries were

developed for use in ANSI C development environments, and VISA-COM libraries

were developed for use in environments that support Microsoft’s Component

Object Model (COM).

VISA libraries allow us to write one version of code that can talk to our instru-

ments over either GPIB or USB, which is nice. Agilent Technologies recom-

mends VISA-COM (versus VISA-C) libraries based on the ease of integration into

advanced ADEs.
