What is IVI?
Autotestcon 2016 www.ivifoundation.org 2
The primary purpose of the Consortium is to:
• Promote the development and adoption of standard
specifications for programming test instrument
• Focus on the needs of the people that use and develop test
systems who must take off-the-shelf instrument drivers and
build and maintain high-performance test systems
• Build on existing industry standards to deliver specifications
that simplify interchanging instruments and provide for
better performing and more easily maintainable programs

• SCPI provided necessary standards based on GPIB needs
- Command strings natural match to GPIB
- HiSLIP allows connection to LXI
• VXIplug&play added drivers necessary for VXI
- Used with other I/O to provide necessary driver
• IVI enhances VXIplug&play with new features & support for current tools
