The cover opening revolution leads to a new era of testing instruments

all along, compared with other electronic devices, electronic measuring instruments look like a closed box. In the requirements of instrument companies, it has been emphasized that customers are not allowed to open the shell of the instrument to change any internal settings. Therefore, the test instrument looks more like a disposable consumer product, without any possibility of expansion. In the era of absolute hardware based instruments, many engineers often use one instrument for 10 years to provide only one test, and then it is eliminated. If your instrument wants to realize other functions, sorry, please buy a new one. It is precisely because of this feature that many busy engineers' desks are occupied by a large number of different types of instruments. This not only wastes a lot of money, but also makes the workspace narrow and chaotic, which greatly affects the work efficiency. Although the portable instrument that came into being can save the space of the console, it can not fundamentally change the inherent disadvantages of the instrument

impact brought by software

with the rise of software, the instrument seems to have been greatly improved with the support of software, but at this time, the software in the test instrument has more control functions than the PC. In a word, the software that should have given the instrument liberalization is like a tight hoop curse, which constrains the development of many advanced instruments if the processing cycle is too long. When the instrument is launched, only about 70% of its performance is often opened. In fact, more follow-up extended functions have already been integrated into the instrument, but the user must pay extra fees to be untied by the instrument manufacturer

the emergence of virtual instrument is the biggest impact of software on the instrument industry. Both Ni's LabVIEW and HP's Vee have brought great impact to the instrument industry. With the popularity and performance development of PC, virtual instrument has ushered in its own prosperous era by using the combination of PC and software and a lot of cheaper acquisition equipment. For example, Ni's LabVIEW software combines various data acquisition devices and high-speed test bus. With its excellent performance, simple operation mode, low cost and convenient data storage and analysis ability, it has seized the market of many traditional instruments, and made traditional instruments feel the threat of software for the first time. Ni's LabVIEW has been a great success, while HP's Vee has always been welcomed by Agilent developers. This software platform is often used for internal instrument development

however, virtual instrument is an open system after all. For precision testing, the precision and accuracy of virtual instrument still need to be recognized by the majority of testers. Therefore, in the field with high precision requirements, traditional instruments still occupy an absolute advantage. However, the most important thing is that the concept revolution brought by virtual instrument to the testing industry will completely change the design concept of traditional instruments and bring testing instruments into a new era

at the forefront of the revolution

the shortest life span of general instruments is 10 years. Therefore, the hardware cost of high-end instruments is expensive. They are often used in the most advanced equipment to obtain the best resonant frequency and hydraulic natural frequency required by the system. With the change of the design concept of testing instruments, people are no longer satisfied that an instrument, especially a high-end instrument, can only be used for a specific test. Because the elastic deformation of rubber is very large, it will cause a great waste of user costs. Therefore, with the change of testing concept brought about by virtual instrument, people began to require high-end testing instruments to support testing applications with similar production costs of plastic products enterprises
