With the development trend of system integration becoming more and more advanced, the applications in various industries are also constantly iterative and updated. Driven by the concept of Internet of things, the development of instrument application field is becoming more and more mature, stable and advanced. System integration combines test software, test instruments and communication technology to solve information processing problems for users. Each separated part of the integration is originally an independent system, and all parts of the integrated whole can work in coordination with each other, In order to give full play to the overall benefits and achieve the purpose of overall optimization.

Popular test instruments such as oscilloscope, digital multimeter, spectrum and LCR tester have gradually changed from the era of manual control to the era of software automatic test. The automatic control in the field of instruments is becoming more and more mature and stable. Such automation not only helps us solve various problems that make test users headache, such as poor test efficiency, boring test process and too much repetitive work, At the same time, it also realizes unified data statistics, analysis and instruction evaluation, which can more intuitively reflect the defects of human and non-human problems in the test process, and realize the management and control of instrument test, which is more targeted, reasonable and standardized.

With the continuous updating of the use requirements of testers, the system integration, on the basis of continuous vertical deepening and horizontal integration, provides testers with solutions with technical standard matching, complete technical interface, reasonable technical equipment and cost economy. The formed instrument system should be advanced, open and resource sharing to realize cost Optimize human resources and create value as efficiently as possible, which plays a quantitative change in promoting product testing, product research and product improvement.

At this stage, instrument integration mostly focuses on the application of internal LAN, but this mode is still in the preliminary stage of instrument integration for the development trend of interconnection of all things. In the future, we will focus on intelligent, remote and big data test instrument control, test data analysis, etc., so as to realize information sharing in the instrument field, Promote the exchange and communication of test schemes among testers from various industries and fields.
