With the continuous innovation and development of information and communication technology and the continuous introduction of various industry standards, the technical and environmental requirements of terminal products such as communication equipment, computers and consumer electronics in R & D, design and production are also getting higher and higher, thus putting forward higher requirements for the application of oscilloscopes. In order to win a place in the market economy, China's oscilloscope industry should not only accurately analyze the current situation and development trend of foreign companies' products, but also carefully analyze the domestic market and demand situation. We should not blindly follow the trend, but should realistically analyze our own actual level, and develop products that meet the characteristics of the Chinese market and the needs of Chinese users at all levels

in order to win a place in the market economy, China's oscilloscope industry should not only accurately analyze the product status and development trend of foreign companies, but also carefully analyze the domestic market and demand situation. We should not blindly follow the trend, but should realistically analyze our own actual level, and develop products that meet the characteristics of the Chinese market and the needs of Chinese users at all levels

oscillograph, as an electronic measuring instrument in time domain, is widely used in the field of measurement. It can be seen everywhere, whether in the research and development, experiment, training of electronic circuits and electronic information systems, or in places such as production and manufacturing, fault diagnosis, test and detection

towards the direction of high bandwidth, high sampling rate and multi-function

with the continuous innovation and development of information and communication technology and the continuous introduction of various industry standards, the technical and environmental requirements of terminal products such as communication equipment, computers and consumer electronics in R & D, design and production are also higher and higher, which also puts forward higher requirements for the application of oscilloscopes

Han Gucheng, deputy general manager of Jiangsu Lvyang Electronic Instrument Group Co., Ltd., said in an interview with China Electronics News that as a basic instrument in the measurement field, the development of oscilloscope should meet the needs of the rapidly developing electronic information industry. The development trend of oscilloscope technology mainly includes the following points: first, from the perspective of performance, it is developing towards high bandwidth and high sampling rate. The most representative t70000 series and 8000 Series can achieve a maximum bandwidth of 20GHz and a sampling rate of 50gs/s, marking that the oscilloscope can carry out high-speed measurement and quasi real-time analysis of microwave and photoelectric signals; Second, the oscillograph waveform capture rate has been greatly improved. The capture rate has increased from thousands of frames per channel 10 years ago to 300000 frames per channel now. This is still a factor for finding the underlying correlation of the information system under the seals and 'under the hood'. 3: the transmission system of the electronic tensile testing machine also has a good growth potential in the use of ordinary rubber. The node data is random Occasional intermittent faults provide fast search and effective statistical analysis, and improve the efficiency of fault diagnosis; Thirdly, the contradiction between sampling rate and storage depth is solved. Previously, high sampling rate and low storage capacity. At present, the ASIC (special integrated circuit) design technology of high-speed large-scale FPGA (field programmable gate array) embedded with high-performance microprocessor CPU and RAM (random access memory) is adopted, and the fast segmented storage technology and hard disk storage are adopted to solve this contradiction. The core processing system of modern oscilloscope signal "acquisition and storage - processing and analysis - display control" works in parallel in the whole process. The pipelined operation is all realized by hardware. In addition to the application of other new technologies, it has been realized that under the condition of the highest sampling rate and high capture rate, the real-time storage depth has been greatly expanded. Agilent dso/dsa90000a series oscilloscope has been achieved under the sampling rate of 40gs/s, Each channel reaches 1g storage depth at the same time, which realizes the complete capture of high-speed and massive data, quasi real-time display and parameter analysis

from the perspective of test function, with the rapid development of electronic information equipment and the diversification of test requirements, oscilloscopes are also constantly developing towards the multi-function of life as samples. Now digital storage oscillograph is not only a time-domain measuring instrument, but also extends to measuring in many fields. Using high-performance microprocessor and ASIC, it can measure and analyze multiple nodes of the tested system in the frequency domain, data domain and statistical domain at the same time. At present, the function classification of oscilloscope has been very vague. Basic general measuring instruments such as oscilloscope and signal source can be integrated into one system, and the trend of function synthesis is obvious

Li Hailong, application engineer of general digital oscilloscope in China of Ricoh, said that in the future, digital oscilloscope will mainly develop in two directions at the same time: continuously improve basic performance, including front-end analog bandwidth, real-time sampling rate, waveform processing speed, and larger waveform storage capacity to meet the needs of the rapid progress of the electronic industry; At the same time, the test instruments including oscillograph should be more humanized, more convenient and more effective to be operated by users, and richer software features should be added to the oscillograph platform to meet the needs of customers' daily stress displacement diversification

domestic manufacturers should start at the low end and gradually move towards the middle and high end.

in recent years, domestic manufacturers have made good achievements in digital oscilloscope market development and technological innovation, but compared with large foreign companies, domestic enterprises still have a big gap. For example, products are mainly aimed at the low-end market, with low technical content and low profits

insiders said that if domestic enterprises want to survive in this market, they must develop towards medium and high-end products

xiezhenbao, assistant to the president of RIGOL, made the following analysis. He said that oscilloscopes can be simply divided into low-end, middle-end and high-end markets according to bandwidth. Generally, the low-end oscilloscope market is below 500MHz, the middle-end market is 500mhz-1ghz, and the high-end market is above 1GHz. In 2007, the low-end market accounted for the largest proportion, with shipments close to 80% of the whole market and market value close to 50%; The shipment volume of the mid-range market exceeds 15%, and the market proportion is about 33%; Although high-end oscilloscopes account for only about 5% of the shipments, they account for 17% of the market share due to their high price

he said that according to the data, the market with the largest proportion is the low-end oscilloscope market, which is the main target of RIGOL at present. This market has a wide range of distribution and many technical applications, which poses a severe challenge to the general ability of oscilloscopes. If domestic product technology has withstood the test in this market, and continues to temper, so that the technical precipitation can be deeper and thicker, and on this basis, continue to march towards the mid-range oscilloscopes, forming a transition and sublimation in technology, then 80% of the market will be done, which is very challenging and attractive. In short, taking a step-by-step route from low-end to high-end is more suitable for Chinese enterprises, more suitable for China's technological development status, and more suitable for China's market needs

Yin Xiaogang, director of the embedded test project Department of Shanghai Yokogawa International Trade Co., Ltd., told that there was no shortcut for Chinese oscilloscope manufacturers to move towards the medium and high-end product market. They must make long-term and substantial investment in research and development, constantly improve their research and development capabilities, and strive to develop high-end acquisition and processing chips with independent property rights as soon as possible

at the same time, he believes that Chinese oscilloscope manufacturers should further improve their production processes and improve their own level through cooperation with some large foreign companies or through their own continuous summary and improvement. "The oscilloscope products of domestic manufacturers, no matter how advanced they are, will lose users in the end if there is no very good quality assurance." He finally emphasized. "To win a place in the market economy, China's oscilloscope industry should not only accurately analyze the current situation and development trend of foreign companies' products, but also carefully analyze the domestic market and demand situation. What can we do? We should not blindly follow the trend. We should realistically analyze our own actual level, and develop products that meet the characteristics of the Chinese market and meet the needs of Chinese users at all levels." Han Gucheng told, "no matter how the oscilloscope function develops, we should first do a good job and refine the oscilloscope system." He stressed that China's oscilloscope industry is still capable of developing medium and high-end oscilloscopes, and there are opportunities to participate in market competition. The whole oscilloscope is developing towards high performance. The realization of technology depends on the rapid development of microprocessors, the rapid development of high-speed and large-scale FPGAs and the decline of prices, which provides a technical basis for the R & D and production of most medium-sized general-purpose oscilloscopes and enter the market competition with higher cost performance. Microprocessors and processing chips for oscilloscopes can be purchased all over the world, which is no longer a problem, The problem is that there is still a big gap between domestic and foreign oscilloscope in process design, material application and reliability, which needs great efforts from the oscilloscope industry

observation

oscilloscope education market attracts manufacturers' attention

for electronic disciplines, oscilloscope is a necessary measurement tool for basic laboratories, and it is also the instrument with the largest amount of configuration. Colleges and universities have a huge demand for oscilloscopes. A few years ago, oscilloscopes were the most purchased for the world bank loan project for the construction of university laboratories

colleges and universities have two kinds of needs for oscilloscopes, medium and low-end oscilloscopes for teaching laboratories and medium and high-end oscilloscopes for scientific research. Therefore, how to occupy a place in this market, each manufacturer has its own tricks

in the digital era, a large number of mixed digital and analog technologies are applied. Mixed signal oscilloscopes are the development trend of social technology in test tools, so schools should train students to be familiar with such test tools. RIGOL launched ds1000cd series products in 2006. So far, this series of products is the only product with 16 channel logic analyzer in the world's low-end oscilloscopes, It is very suitable for the current teaching needs of schools. Now, many famous colleges and universities have cooperated with RIGOL to establish joint laboratories in order to further promote the application of mixed signal oscilloscope in teaching

college teaching laboratories and scientific research laboratories have completely different requirements for oscilloscopes. For teaching laboratories, Agilent mainly provides dso3000 Series Oscilloscopes with lower prices, which provide some unique functions to make students familiar with more technologies, such as dso3000 supporting DSP filtering technology and pass/fail test function; For scientific research laboratories, low-cost and high-performance oscilloscopes are provided, such as mixed signal oscilloscopes with 1GHz, 500MHz and 350MHz bandwidths, as well as low-cost mixed signal oscilloscopes with 100MHz bandwidths, which are convenient for single-chip computers, FPGAs and other occasions that need to test mixed signals, and Series Oscilloscopes that support vector signal analysis. The standard test software 89601 in the field of wireless testing is used to test and analyze various wireless signals, and a series of oscilloscopes that support power signal analysis. Agilent brings the power automatic test software to oscilloscopes on non windows platforms, which greatly reduces the cost

as the creator of oscillograph, American tech company has also coveted the college market for a long time. For high-end applications developed by colleges and universities, they can provide a complete high-speed serial technology test platform, a unique digital RF technology test platform and a comprehensive embedded system technology test platform. The products mainly include high-speed oscilloscope, high-speed signal source and powerful
