National Instruments (NI) recently introduced a new GPIB-140A fiber optic GPIB extender designed to meet the higher requirements for test system connection distance and device volume in research and industry. This extender provides powerful support for automated testing and data acquisition with its high-speed data transfer capability, long cable extension, and the ease of no modification to existing software.

The GPIB-140A fiber optic GPIB extender uses advanced buffering transmission technology to support transmission rates up to 1.1 Mb/s (IEEE 488.1 standard) or 2.8 Mb/s (HS488), ensuring high data transmission speed and reliability. In addition, the device is able to expand the number of GPIB devices in the GPIB system from 15 to 26, greatly enhancing the scalability and flexibility of the system.

Another notable feature of the extender is its significant increase in cable length. According to the IEEE 488 standard, the total cable length of GPIB systems usually cannot exceed 20 meters, and the GPIB-140A is able to extend this limit to 1 km, greatly improving the spatial layout flexibility of the test system.

The introduction of the GPIB-140A not only demonstrates NI’s continued innovation in the field of test and measurement, but also demonstrates its deep understanding of customer needs. Whether in a laboratory environment or an industrial automated production line, the extender provides a stable and efficient connection solution.

Concluding remarks:
With the introduction of the GPIB-140A fiber optic GPIB extender, NI has once again demonstrated its technical leadership in the field of test and measurement. We expect this extender to play an important role in future scientific and industrial applications, enabling customers to achieve more efficient and accurate test and measurement.”
