The hottest testing and measuring instrument techn

  • Detail

Test and measurement instrument technology has officially entered the era of 2.0

some recent events in the test and measurement instrument market seem to imply that the industry has entered a new stage. The first thing to mention is Agilent technology. Although the company once believed that PXI was not the future trend of testing and measurement technology, it launched two acquisitions (acqiris and pxit) for the technical solution supplier at the end of 2006, and announced to join the PXI alliance at the end of March 2007

it is also worth noting that with the assistance of Ni company, this leading oscilloscope manufacturer has adopted the interactive measurement software provided by Ni in its TDS1000B, TDS2000B and DPO4000 series digital storage oscilloscopes, which helps engineers easily connect and control Tektronix instruments on PC. In addition, jishili, a supplier of testing instruments, also followed the trend and launched a product line in line with PXI standards in December 2006

the above cases show that the way of taking software as the center and cooperating with modular i/o hardware has gradually become a trend in the test and measurement instrument industry, and this is the virtual instrument technology (VI) that Ni has been vigorously promoting. This shows the correctness of the road (3) installing the spherical lower platen on the platen that Ni has adhered to for 30 years. When meeting with the industry media in Shanghai, Ms. Zhu Jun, marketing manager of Ni China, said that when Ni proposed the concept of virtual instrument technology, many people believed that it could not become the mainstream technology. What we see today is that VI has not only become the development direction of testing and measuring aerogel gel materials, which is known as the lightest solid industry in the world, but also clearly, the testing and measuring industry has entered the era of instrumentation2.0

instrumenation2.0 borrows the recently popular concept of Web2.0, which highlights the strong demand of users for data control and customized understanding of their own needs for experimental parameters

taking software as the center and combining modular hardware to add as many new functions as possible to the product in the shortest time, which seems to have become the biggest challenge facing electronic system design engineers at present. The test system must keep up with the development of the product technology to be tested, but the improvement of the complexity of the system to be tested and the requirement of the test time make the traditional test technology more and more unable to meet the excessive test requirements. Under the traditional measuring instrument technology, engineers have only two choices: either develop a special testing solution for the product, or use a general testing instrument. However, the special system is expensive, while the general instrument is difficult to meet the test requirements

compatible with the advantages of the above two schemes, the software centered system has opened a new era. This method can provide design and test engineers with the most efficient and cost-effective way to create their customized instrument system. Zhu Jun said that it is Instrument Technology 2.0

Jane TPE industry is gradually entering a period of innovation. On the one hand, Instrument Technology 2.0 is relative to the era of 1.0, which completely relies on hardware to realize testing and measurement: in the latter way, the hardware itself and its analysis functions are defined by the instrument supplier, and it is impossible for users to realize customization. Even if the instrument is connected to PC, the information transmitted is also the test result defined by the manufacturer, Users cannot obtain the measured raw data for custom analysis. The 2.0 method is completely different. After obtaining real-time raw data, engineers can use software to design their own user interface and customize measurement tasks to obtain the required analysis results
