The IEEE 488 INTERFACE with Test Access or GPIB interface manufactured by Gossen Metrawatt is an industry-standard communication interface that allows for communication between various electronic devices. It is used for data exchange between different physical and digital systems, computers, and instruments, and is now the most common type of instrument interface for electronic instruments. The IEEE 488 interface is motivated by the designs developed by HP as part of their HP-IB instrument bus in the early 1960s. This interface is both simple and robust, with features such as an 8-bit data bus, built-in error-correction and de-skew circuitry, and 100% compatibility with the full IEEE-488/IEC-60625 standards. It is used in embedded systems, test and measurement systems, military applications, analytical instruments, research labs, and various other industries. The Gossen Metrawatt IEEE 488 provides a highly but cost-effective solution for instrument control that delivers consistent results in different environments.
