Know yourself and know your enemy, never lose a hundred battles! In order for domestic instrument manufacturers to achieve further development, in addition to improving their own technical capabilities, it is also very important to learn from the experience of foreign instrument industry development.

The foreign instrumentation industry mainly focuses on the following aspects: new technologies are widely applied. Currently, electronic design automation (EDA), computer-aided manufacturing (CAM), computer-aided testing (CAT), digital signal processing (DSP), application specific integrated circuits (ASIC), and surface mount technology (SMT) are commonly used in foreign instrumentation. Instrumentation=AD/DACPU software pays attention to the development and production of high-tech and large-scale products while emphasizing the development of high-end instruments. Emphasis is placed on system integration, not only focusing on individual machines, but also on system and product softening.

With various instruments and meters being equipped with CPUs and digitized, huge manpower and financial resources have been invested in software. In the future, instruments and meters can be summarized into a simple formula: "Instruments and meters=AD/DACPU software". The AD chip converts analog signals into digital signals, which are then processed and converted by software before being output using DA. Market driven product development guidelines have shifted from technology driven to market driven, and from blindly pursuing high precision to "just right". The criteria for developing a successful product are: users have clear needs; Can be launched into the market with the shortest development time; The functionality and performance should be just right; Another change in product development guidelines is the direction of contraction and the concentration of advantages. The specialized production process adopts an automatic testing system.

At present, GP-IB instruments are often used to build automatic testing systems, with large testing cabinets on the production line for rapid automatic testing, statistics, analysis, and printing of results.
