Welcome to the Interchangeable Virtual Instruments Foundation

The IVI Foundation is an open consortium founded to promote specifications for programming test instruments that simplify interchangeability, provide better performance, and reduce the cost of program development and maintenance.


The IVI Foundation has been collaborating with the LXI Consortium to update the IVI standards for secure instrument network communication. For details on these updates:

  • Press Release - IVI and LXI Leading the T&M Industry in Security Standardization

  • Article - IVI Standard Updates for Secure Network Connections

  • LXI Consortium Security Updates

  • VXIplug&play

    The VXIplug&play Systems Alliance was an organization whose members shared a common commitment to end-user success with open, multivendor VXI systems. For more information, click here.





    The Standard Commands for Programmable Instrumentation (SCPI) Consortium was an organization whose members shared a common commitment to develop a common interface language between computers and test instruments. For more information, click here.



    IVI Overcomes Industry Challenges

    In today's world two factors hinder efficient test system setup and support:

    1) the high cost of developing and maintaining test system software and, 2) rapidly evolving technology. The IVI Foundation addresses these needs through new driver technology:

    IVI drivers define a new level of quality, completeness, usability, and functionality that reduces the cost of test system development and ownership.

    IVI drivers simplify upgrading or replacing components in complex test systems intended to be used over a long period of time. The IVI Foundation was formed in 1998 and officially incorporated in 2001. Its membership includes end-users, instrument vendors, software vendors, system suppliers, and system integrators.
