The Keithley KPCI-488A is a PCI bus GPIB interface card that enables host computers to communicate with GPIB-compatible instruments and devices. It functions as both a talk/listen device and system controller, managing up to 14 instruments across distances of 20 meters. The card transfers data at rates up to 1 Mbyte/s (1.5 Mbyte/s for the KPCI-488LPA variant) and operates in compliance with IEEE-488.2 standards. Built-in utility software, diagnostic tools, and command-compatible drivers streamline integration into automated test systems, data acquisition setups, and instrument control applications.
