ENGINEERS and scientists now can use the latest USB standard, USB 2.0 high-speed, to control GPIB instruments at transfer rates of up to 8MB/s (64Mb/s).

The new National Instruments GPIB-USB-HS, the industry's fastest USB-to-GPIB controller, is the latest in the broad offering of NI instrument control products for PCI Express, Ethernet, PCI, USB, PCMCIA and other interfaces.

The NI GPIB-USB-HS controller incorporates an NI TNT GPIB ASIC and a USB 2.0 high-speed chip to achieve GPIB transfer rates comparable to those of the high-performance NI PCI-GPIB plug-in board.

With GPIB transfer rates of up to 1.8MB/s (14.4Mb/s) in standard IEEE 488.1 and 8MB/s (64Mb/s) in high-speed IEEE 488.1 (HS488), the NI GPIB-USB-HS provides a 2X performance improvement over existing USB-to-GPIB controllers.

With the GPIB-USB-HS, engineers can run existing GPIB applications without modifying their code because the controller uses the popular NI-488.2 and Virtual Instrument Software Architecture (VISA) APIs.

The controller comes with NI-488.2 and NI-VISA driver software for Windows 2000/XP and works with NI LabVIEW, LabWindows/CVI (ANSI C) and Measurement Studio for Visual Studio (Visual Basic/C/C++/C#) through the NI-VISA and NI-488.2 driver software.
