Keithley's GPIB interface solutions make it easy to add standard IEEE-488.2 bus control to any PC system.

The Keithley Model KUSB-488B USB-to-GPIB interface turns any computer with a USB port into a fully functional GPIB controller. The KUSB-488B's small form factor makes it perfect for use with laptop computers in portable applications or for other applications in which the computer has no available PCI plug-in board slots. The product is USB 2.0 compliant and has an IEEE data transfer rate upwards of 1.5 MB/s through the USB port. No external power is required. The KUSB-488B has a built-in 2-meter USB cable.
