The compact NI GPIB-USB-HS transforms any computer with a USB port into a full-function, IEEE 488.2 controller that can control up to 14 programmable GPIB instruments. The small size and light weight of this controller make it ideal for portable applications using a laptop computer or other applications in which the computer has no available internal I/O slots. The GPIB-USB-HS works with Windows 7/Vista/XP/Me/2000/98, Mac OS X, and Linux computers with a USB port.
