application will compile, link, and execute without error. The test results, however, may be quite different because different instruments measure and generate signals differently. For more information on class- compliant interfaces and capability groups, visit www.ivifoundation.org.

Using Class-Compliant Interface

Generally, you gain no advantage from using class- compliant interface over using just the instrument- specific interface. However, if you can isolate the usage of the instrument- specific interface, you may see some advantages. Replacing the IVI- COM driver then involves fixing the syntactic incompatibilities in the isolated code.

IVI- COM drivers will be provided to users. The drivers can also be used in a variety of development environments. For more information on IVI, visit www.ivifoundation.org.

Below are the IVI- COM drivers provided:

AgilentVEE support through COM mechanism using IVI- COM

Visual Basic 6 support through COM mechanism using IVI- COM

C++ support through COM mechanism using IVI- COM

Visual Basic 7 support through COM Interop mechanism using IVI- COM

C# support through COM Interop mechanism using IVI- COM

National Instruments LabVIEW support through COM mechanism using

IVI- COM

The Agilent firmware update utility is provided to allow users to update firmware on instruments. Update is made available through Agilent Developer Network (ADN) website:
