Data conversion specialist Acqiris has introduced a range of class-compliant Interchangeable Virtual Instrument (IVI) drivers that support the company's full range of digitizers. The IVI drivers, available at no charge, provide a set of standard commands for a given class of instruments that simplify programming and instrument swapping among data conversion products, the company said.

Developed mainly for the ATE market, the drivers comply with IviScope Class (IVI-4.1) specifications, which are designed to support typical oscilloscopes as well as common extended functionalities found in more complex DAQ instruments. Specifically, the drivers can be used in conjunction with the specifications outlined in the IVI-4.1 IviScopeWaveformMeasurement and IviScopeAverageAcquisition extension groups.

The new drivers support all major test platforms supported by Acqiris, including PCI, PXI, CompactPCI and VXI, facilitating hardware independence without rewriting software, the company said. They are implemented as a Microsoft Component Object Model (COM)-based IVI-COM driver that enables them to operate seamlessly in numerous integrated development environments. An IVI-C interface on the drivers allow for additional hardware and software compatibility.

The IVI standard, supported and maintained by the IVI Foundation, builds on top of the Virtual Instrument Software Architecture (VISA) layer. The aim of IVI is to give users a degree of instrument interchangeability, instrument simulation, and in some cases, higher performance. The new IVI drivers help foster the commitment of instrument manufacturers to industry standards, Acqiris said.

The company is in the process of registering the new drivers with the IVI Foundation. Upon completion of this process, the driver will be downloadable from the Acqiris website.
