The National Instruments PCI-GPIB/LP is a low-profile GPIB interface card for PCI bus systems, delivering high-speed instrument control and data acquisition in compact form factor. It connects directly to standard IEEE 488 instruments via a 24-pin GPIB connector and operates in both 3.3 V and 5 V PCI slots without external power. Built on proven PCI-MITE and TNT ASICs, this card combines IEEE 488.1 and High-Speed GPIB (HS488) protocol support for flexible test automation and measurement applications.
