NI GPIB-140A Fiber GPIB Expander

1、 Core positioning
The fiber optic GPIB signal expansion equipment launched by NI (National Instruments of the United States) can connect traditional GPIB interface instruments (such as oscilloscopes and multimeters) over long distances through fiber optics, solving the problems of short transmission distance and weak anti-interference of ordinary cables, and adapting to industrial testing, laboratory measurement and other scenarios. ​
2、 Core functions
Long distance signal extension: With the help of fiber optic transmission, GPIB signals can be transmitted up to 2000 meters (multimode fiber), far exceeding the 15 meter limit of ordinary GPIB cables. ​
Strong anti-interference ability: Fiber optic transmission isolates electromagnetic interference (EMI) and radio frequency interference (RFI), suitable for precise data transmission in industrial strong interference environments. ​
Flexible compatibility and adaptation: Supports IEEE 488.1/488.2 GPIB protocol, can connect various GPIB instruments such as oscilloscopes, signal generators, data acquisition cards, etc. ​
Stable and reliable operation: Equipped with a built-in fault diagnosis indicator light, it can quickly determine the connection status; Support hot plugging, no need to power off during maintenance, ensuring continuity of testing. ​
