USB GPIB controllers
National Instruments has released two new GPIB controllers, including a Mac compatible USB controller, the NI USB-GPIB-HS, and a Windows compatible low profile (LP) PCI Express controller, the NI PCIe-GPIB. The USB device is claimed to offer speeds up to 1.8MB per second using IEE 488.1 or 7.2MB per second with HS488. The cable can be connected directly between any GPIB instruments and a computer running Windows, Linux, or Mac operating systems.
The low profile PCI Express card includes NI-488.2 software for Windows Vista systems. Maximum data transfer speeds are listed as 1.5MB per second on IEE 488.1 or 7.9MB per second with HS488. A cable is required for connection between the card and GPIB instruments.
Both controllers are RoHS compliant and can be programmed to work with LabVIEW graphical system, NI LabWindows development environment, or NI Measurement Studio software. Both the NI GPIB-USB-HS and NI PCIe-GPIB/LP devices are priced at $550.
