Keywords:.NET  Visual Studio  VISA COM I/O 

Microsoft .NET architecture, with its C# and Visual Basic programming languages and the Microsoft Visual Studio development environment, is intended for test and measurement programmers. There is only one problem: doing actual instrument communication.

The VISA COM I/O API is a programming interface standardised by the IVI Foundation for communicating with instruments over GPIB, LAN, USB, RS-232, or other hardware interfaces. Agilent Technologies has an implementation of the VISA COM I/O standard that works with Agilent I/O hardware as well as the computerstandard I/O interfaces. VISA COMI/O is an update of the older VISA C API to work in and with Microsoft's COM technology.

The examples in this application note were developed using C# 2003 and Visual Basic 2003 as part of Visual Studio 2003 Professional Edition. We will commonly call them C# and VB throughout this application note.
