Keithley KPCI-488A

The Keithley KPCI-488A is a PCI bus interface card that adds IEEE-488.2 (GPIB) connectivity to personal computers. It enables control and communication with up to 14 GPIB-compliant instruments across control distances up to 20 meters, functioning as either a talk/listen device or system controller. The card delivers data transfer rates up to 1 Mbyte/s and integrates with Windows operating systems through included universal language drivers and diagnostic utilities.
