The company started out making GPIB controllers, and twenty some odd years later they’re at it again. This time around, Austin, TX-based National Instruments debuts the industry’s first GPIB controller that uses the new PCI Express interface.
The PCIe-GPIB, as the product is called, relies on NI’s TNT GPIB ASIC, making it able to sustain data transfer rates of more than 1.5 MBit/sec using the IEEE 488.1 three-wire interlocked handshake. What is more, it also implements the IEEE 488.1 noninterlocked handshake (HS488) for benchmarked data transfers at more than 7.9 MBit/sec.
The NI PCIe-GPIB controller comes with a suite of software development tools to get applications up and running quickly. Engineers can use the NI PCIe-GPIB with NI-488.2 driver software and any NI development environment including LabVIEW, LabWindows/CVI and Measurement Studio for Microsoft Visual Studio.
The new GPIB controller complements the company’s portfolio of GPIB controllers that includes the NI GPIB-USB-B, NI GPIB-ENET/100 and NI PCI-GPIB.
PCI Express itself is a high-performance, point-to-point serial interconnect that improves PCI by providing scalable bus bandwidth. PCI Express features a layered model that offers backward compatibility with existing PCI applications at the operating system level. In addition, PCI Express offers critical features such as guaranteed bandwidth for demanding data acquisition applications.
