Go-based implementation of the Interchangeable Virtual Instrument (IVI) standard.

The IVI Specifications developed by the IVI Foundation provide standardized APIs for programming test instruments. This package is a partial, Go-based implementation of the IVI Specifications, which are specified for C, COM, and .NET.

The main advantage of the ivi package is not having to learn the SCPI commands for each individual piece of test equipment. For instance, both the Agilent 33220A and the Stanford Research Systems DS345 function generators can be programmed using one standard API. The only requirement for this is having an IVI driver for the desired test equipment.

Currently, ivi doesn't cache state. Every time an attribute is read directly from the instrument. Development focus is currently on fleshing out the APIs and creating a few IVI drivers for each instrument type.

The ivi package requires receiving an Instrument interface. The following gotmc packages meet the Instrument interface:

• visa — Calls lxi or usbtmc as needed, so that you can identify instruments using a VISA resource address string.
• lxi — Used to control LXI enabled instruments via Ethernet.
• usbtmc — Used to control USBTMC compliant instruments via USB.
• prologix — Used to communicate with instruments using a Prologix GPIB
• controller.
