Interchangeable Virtual Instruments (IVI) style drivers
The IVI Foundation
instruments, including digital multimeters, arbitrary waveform/function generators, dc power supplies,
ac power supplies, oscilloscopes, switches, spectrum analyzers, RF signal generators, and
power meters.
There are two types of IVI drivers, IVI-COM and IVI-C. IVI-COM drivers use Microsoft
technology to expose driver functionality. IVI-C drivers use conventional Microsoft
to export simple C-based functions.
For more information about IVI drivers and the differences between the COM, C, and .NET interfaces,
see Understanding the Benefits of IVI
(ivifoundation.org/docs/Understanding%20the%20Benefits%20of%20IVI[3].pdf).
NI CVI runtime engine
IVI-C drivers that are created using the National Instruments (NI
depend on either the CVI runtime DLL (cvirte.dll) or the instrument support runtime DLL
(instrsup.dll). These DLLs must be present on the system for them to run.
NI IVI Compliance Package
The National Instruments (NI
IVI class drivers and support libraries that are needed for the development and use of applications
that leverage IVI instrument interchangeability. The IVI Compliance Package also is based on and is
compliant with the latest version of the instrument programming specifications defined by the IVI
Foundation.
The NI ICP installer installs the IVI shared components, CVI runtime engine, and the instrument
support runtime engine.
Keithley I/O layer
The Keithley I/O Layer (KIOL) is a software package that contains several utilities and drivers. It is
mainly used as a supplement to IVI drivers or application software like Test Script Builder (TSB).
For additional detail on the Keithley I/O layer, including computer requirements and installation
