The NI GPIB-USB-HS+ is a high-speed IEEE 488 controller that bridges GPIB instruments to a host computer via USB 2.0. It enables direct PC-to-instrument communication with data throughput up to 1.4 MB/s on the GPIB bus and up to 480 Mb/s over USB, delivering dependable control across a broad spectrum of legacy and modern test equipment. The controller operates as a GPIB controller, listener, and talker, making it suitable for applications requiring efficient instrument automation and multi-device coordination.
