The oscilloscope market is growing steadily
As one of the most commonly used general-purpose devices in the electronics industry, the oscilloscope market has been growing steadily for decades, with annual sales of more than $ 1 billion. Research data shows that oscilloscopes currently occupy about one-third of the market share in China's general test market products, and their market share has increased compared to the previous ones. This further shows that the oscilloscope's market position in the overall test and measurement instrument products is gradually strengthening.
With the continuous improvement of the needs of users of oscilloscopes in various industries and the continuous improvement of corresponding performance, the important role of oscilloscopes in the entire test and measurement industry will become increasingly prominent.
According to Du Jiwei, marketing manager of Agilent Technologies' Digital Test Department in Asia Pacific, most people believe that the advent of the digital age will drive the market of logic analyzers. In fact, it is driving the popularity of oscilloscopes in more ways, as follows:
First, the widespread application of FPGAs (field programmable gate arrays), even the design of dedicated chips, is often prototyped with FPGAs first. Complex FPGA verification requires a logic analyzer, but mixed signal oscilloscopes are sufficient in many cases .
Second, the popularity of serial buses (microcontrollers and programmable devices), in order to reduce the size of electronic products, engineers tend to convert the original data on the parallel bus into a serial format with one or two signal lines To deliver, all physical layer tests of the bus require the use of an oscilloscope.
Third, many parts that were originally implemented with analog circuits are transferred to digital circuits. The parts that were originally tested with spectrum analyzers are now tested with oscilloscopes or logic analyzers.
Fourth, digital video has evolved from DVI (digital video interface) to HDMI (high-definition multimedia interface) and DisplayPort, and mobile video technology has MIPI (mobile industry processor interface), which requires oscilloscopes to complete conformance tests; for example , MIPI has just been adopted by some companies, and the test plan has been launched. "Therefore, in the digital age, oscilloscopes not only play a role, but also play a more role, in some ways even surpass the role of traditional oscilloscope." Du Jiwei said.
Perhaps because of the important role of the oscilloscope, R & S is determined to take a slice of the cake in this field. Wu Ke, chief representative and general manager of R & S China, said: "The launch of oscilloscope products is a milestone for R & S. R & S will strive for the top three positions in the world even if it takes 10 or 15 years in the oscilloscope field."
Technology is developing towards multiple trends
The development of oscilloscope technology to the present day is basically a world dominated by American companies. The $ 1 billion oscilloscope market includes a variety of applications, so manufacturers introduce different oscilloscopes to meet the needs of different occasions. And several major companies that play a leading role have led the continuous development of oscilloscope technology.
Du Jiwei told reporters that the future trend of oscilloscope technology is often determined by several factors, including time-to-market pressure, technology maturity, industry needs, and peer competition and interaction. He believes that low-end oscilloscopes focus on price and high-end oscilloscopes focus on performance, so the development trend of technology is not in a single direction, but in several or more directions.
Rohde & Schwarz (R & S) China Co., Ltd. Dr. Zhigang Ma summarized the demand for oscilloscopes: excellent RF front-end, high-precision digital sampling system, high waveform capture rate, diverse and stable trigger system, and greater storage Depth, more application options and easier to use.
Bandwidth is very important for oscilloscopes. Du Jiwei said that taking high-end real-time oscilloscopes as an example, the current highest bandwidth is the 32GHz bandwidth 90000X series oscilloscopes introduced by Agilent. Its core technology is the preamplifier bandwidth directly to 32GHz analog bandwidth. This is because Agilent has mature indium phosphide semiconductor process technology, as well as RF microwave three-dimensional packaging technology, and solves the technical problem of applying aluminum nitride scattering materials in chipset packaging, and companies that have not yet mastered this high-end technology must Think of other ways to increase the oscilloscope bandwidth.
In an interview with China Electronics News, Deng Jinhui, technical marketing manager of Tektronix 'Greater China distribution business, said that increasing the number of channels should also be a trend for oscilloscopes to meet the needs of embedded design engineers, and hybrid oscilloscopes are the ideal solution. "In October last year, Tektronix launched the industry's first high-performance mixed-signal oscilloscope MSO70000, with a bandwidth of up to 20GHz, which is currently the world's fastest mixed-signal oscilloscope." Deng Jinhui said.

Competition is getting fiercer
It can be seen that the entire oscilloscope market is subdivided according to bandwidth (application), which can be divided into high-end market (above 4GHz), mid-end market (350MHz to 1GHz), and low-end market (below 500MHz). The definition and division of each company Slightly different. At present, the main foreign manufacturers in this field are Tektronix, Agilent, LeCroy, and the newly entered R & S. Of course, there are many local manufacturers. Among them, there are currently the highest bandwidth 1GHz oscilloscopes.
Deng Jinhui said that Tektronix currently provides a complete range of oscilloscopes from 40MHz to 20GHz to meet the widest application needs in the market. "You can see that the mid-end and low-end markets are receiving more and more attention from manufacturers. Because this market has a huge user base, from R & D, production to basic education, there is great potential for development. Everyone Coveted this piece of cake, of course, also attracted some new manufacturers to join. "Deng Jinhui concluded.
"At the high end, Agilent, with its absolute advantage in signal integrity, has gradually expanded its market share and basically has an overwhelming advantage in HDMI." Du Jiwei told reporters. From an application point of view, Agilent emphasizes and expands its hardware rapid response capability, as well as its advantages in circuit development and debugging, and finding occasional faults. On its non-Windows platform (InfiniiVision series) oscilloscope, the unique technology makes the waveform capture rate Under deep storage conditions, it can still be up to 100,000 waveforms per second. In future new products, Agilent will further use this core technology to extend more additional functions and expand its appeal to R & D customers. In the production customer base, they share a slice of soup with their unique LXI small-size, panelless oscilloscope. The bandwidth of the modular oscilloscope has now covered 13GHz.
For R & S companies that have newly entered the oscilloscope field, they also occupy part of the market with two series of products. Their RTO product series, with bandwidths of 1GHz and 2GHz, are positioned in the field of high performance requirements; RTM product series, with a bandwidth of 500MHz, are mainly used in communication electronic signal measurement Field, to meet the needs of scientific research, schools, production, maintenance and so on.
