IVI Driver

Communicate with instruments that use an IVI driver

To use instruments via the IVI interface, you need to install IVI drivers, VISA, and shared components. For information about these requirements, see Getting Started with IVI Drivers.

You can use the MATLAB IVI-C Wrappers provided with the Instrument Control Toolbox with IVI drivers of the same class. Supported IVI driver classes include IviScope, IviFgen, IviSwitch, IviRFSigGen, and many others. For information and examples, see Using IVI-C Class-Compliant Wrappers.

Quick-Control Oscilloscope, Function Generator, and RF Signal Generator are easy to use interfaces that let you communicate with scopes, function generators, and RF signal generators without dealing with the underlying driver. For requirements and examples, see Quick-Control Interfaces.

Examples and How To

Getting Started with IVI Drivers

Examine your IVI driver installation. Create MATLAB^® IVI instrument drivers. Create device objects for MATLAB IVI instrument drivers.

Using IVI-C Class-Compliant Wrappers

The IVI-C wrappers provide an interface to MATLAB for instruments running on IVI-C class-compliant drivers.

Concepts

IVI Drivers Overview

Instrument Control Toolbox™ can communicate with instruments using Interchangeable Virtual Instrument (IVI) drivers. The toolbox supports IVI-C drivers, provided by various instrument manufacturers.

Instrument Interchangeability

With IVI^® class-compliant drivers, you can exchange instruments with minimal code changes.

IVI Configuration Store

Examine and configure your IVI configuration store.
