The NI GPIB-USB-B is a USB-to-GPIB controller that connects legacy IEEE 488 instruments directly to modern computers. It operates as a full GPIB node—functioning as Controller-in-Charge, Secondary Addressable device, Listener, or Talker—and delivers up to 1.4 MB/s data transfer rates. The device bridges GPIB test equipment into contemporary automated measurement systems without requiring additional interface cards or external power.
