![]() With the GPIB-USB-HS, engineers can run existing GPIB applications without modifying their code because the controller uses the popular NI-488.2 and Virtual Instrument Software Architecture (VISA) APIs. With GPIB transfer rates of up to 1.8 MByte/s (14.4 Mbit/s) in standard IEEE 488.1 and 8 MByte/s (64 Mbit/s) in high-speed IEEE 488.1 (HS488), the NI GPIB-USB-HS provides a 2X performance improvement over existing USB-to-GPIB controllers. The NI GPIB-USB-HS controller incorporates an NI TNT GPIB ASIC and a USB 2.0 high-speed chip to achieve GPIB transfer rates comparable to those of the high-performance NI PCI-GPIB plug-in board. The new National Instruments GPIB-USB-HS, claimed to be the industry’s fastest USB-to-GPIB controller, is the latest in the broad offering of NI instrument control products for PCI Express, Ethernet, PCI, USB, PCMCIA and other interfaces. Engineers and scientists now can use the latest USB standard, USB 2.0 high-speed, to control GPIB instruments at transfer rates of up to 8 MBytes/sec.
