HP manual Class IVI Driver

vendor’s instrument and not need to relearn the commands. Also commands that are common to all drivers, such as Initialize and Close, are identical regardless of the type of instrument. This commonality lets you spend less time hunting around the help files and programming an instrument, leaving more time to get your job done.

That was the motivation behind the development of IVI drivers.The IVI specifications enable drivers with a consistent and high standard of quality, usability, and completeness. The specifications define an open driver architecture, a set of instrument classes, and shared software components. Together these provide consistency and ease of use, as well as the crucial elements needed for the advanced features IVI drivers support: instrument simulation, automatic range checking, state caching, and interchangeability.

The IVI Foundation has created IVI class specifications that define the capabilities for drivers for the following eight instrument classes:

Class

IVI Driver

 

 

Digital multimeter (DMM)

IviDmm

Oscilloscope

IviScope

Arbitrary waveform/function generator

IviFgen

DC power supply

IviDCPwr

Switch

IviSwitch

Power meter

IviPwrMeter

Spectrum analyzer

IviSpecAn

RF signal generator

IviRFSigGen

 

 

IVI Class Compliant drivers usually also include capability that is not part of the IVI Class. It is common for instruments that are part of a class to have numerous functions that are beyond the scope of the class definition. This may be because the capability is not common to all instruments of the class or because the instrument offers some control that is more refined than what the class defines.

IVI also defines custom drivers. Custom drivers are used for instruments that are not members of a class. For example, there is not a class definition for network analyzers, so a network analyzer driver must be a custom driver. Custom drivers provide the same consistency and benefits described below for an IVI driver, except interchangeability.
