I. Successfully developed a microwave millimeter wave vector network analyzer We have successfully developed a microwave millimeter wave vector network analyzer called "the king of the world electronic measuring instruments". With the development of China's new system electronic information system and new weapons and equipment, the occupation and utilization of limited spectrum resources has become an important feature of high-tech development and military electronic technology and equipment development, which fully utilizes the amplitude and frequency of electromagnetic waves in spectrum resources. Phase and polarization information is a core feature of modern electronic equipment. However, the development of modern electronic equipment is in urgent need of a high-performance vector network analyzer that can simultaneously obtain the amplitude, phase and group delay characteristics of the measured object. Especially the universal application of radar phased array technology, the testing requirements for phase and group delay characteristics are getting higher and higher, so the vector network analyzer becomes a necessary and critical test equipment for modern electronic equipment, and other test equipment cannot. An important means of detection to replace. In addition, microwave millimeter wave active device CAD technology is becoming more and more popular, and the basis of active CAD is to extract the S parameters of active devices. Currently, only vector network analyzers have the ability to simultaneously obtain the S parameters of active devices, so that CAD design results Closer to the actual application. In addition, vector network analyzers have moved beyond traditional linear network applications and play an important role in the testing and analysis of nonlinear, high-power networks. In addition, the vector network analyzer can be used as the core to form an automatic test system for antennas, RCS, high power, T/R components, etc., so its application field will be very broad.
In order to meet the urgent needs of China, the 41st Research Institute of Electronics of the Ministry of Information Industry has successfully developed a high-level vector network analyzer. The outstanding features of the instrument mainly include the following aspects:
1. Working frequency bandwidth, one-frequency scanning can complete the measurement of amplitude-frequency characteristics and phase-frequency characteristics of the whole frequency range from 45MHz to 40GHz.
2. The measurement accuracy is high. Due to the error correction technology, the influence of system error on the measurement result is greatly reduced. Even if a non-ideal hardware circuit is used, high-precision measurement can be obtained.
3. Large dynamic range, because the vector network analyzer uses high-sensitivity amplitude-phase receiver technology and digital signal processing technology, it improves the sensitivity of small-signal test and expands the test dynamic range.
4. High-speed real-time testing, due to the use of embedded high-speed computer technology, the process of measurement calibration, measurement control, error correction, display control and other programs are programmed and softwareized, which improves the degree of automation and test speed, making real-time measurement possible.
After 41 years of hard work, the Vector Network Analyzer developed by the Ministry of Information Industry has been serialized and family-oriented. There are more than ten models available for users to choose from, including coaxial and waveguide calibration components. The test accessories are complete and the matching is strong, which can meet the testing requirements of different levels of users. The frequency range can be selected from 0.0003 to 110 GHz. The successful development of the domestic vector network analyzer makes the design and manufacturing level of China's vector network analyzer into the world's first rank, becoming the second country in the world to master this technology after the United States. The technical level and variety of products can be Compared with similar foreign products, through the development of vector network analyzer, we have mastered a variety of automatic measurement technology and automatic test system with vector network analyzer as the core.
Second, master the modulation domain test technology, the development of the modulation domain analyzer modulation domain test technology is a new test technology field that appeared at the end of the 20th century. It has become the current "three" with the time domain test and frequency domain test that we are familiar with in the past. Domain" testing technology. The time domain test measures the signal value of the input signal as a function of time and is the relationship between the signal amplitude and time. The frequency domain test is a measurement of the signal value of the input signal as a function of frequency, and is the relationship between the amplitude of the signal and the frequency. The modulation domain test measures the frequency value of the input signal as a function of time. The resulting display pattern represents the modulation domain of the signal and is the relationship between the frequency value of the signal and time. Modulation domain testing technology is an emerging and very important test technology, which depends on the rapid development of science and technology and electronic equipment. As we all know, most electronic information transmissions in the past are amplitude change information. Now, after turning to digital information, information is increasingly transmitted as a timing or phase relationship between digital pulses, using an oscilloscope or a spectrum analyzer alone. A class of amplitude-based instruments cannot satisfy the need to characterize these digital signals. A new method of phase digitization was proposed. This method is very suitable for measuring timing signals, phase encoded signals or frequency encoded signals. The emergence of modulation domain testing technology will definitely make new contributions to many test problems. It has been proved that modulation domain analysis technology has become an indispensable testing technology in more and more application fields, especially in the field of military electronic testing.
For example, with the introduction of new digital communication technologies such as integrated digital networks and synchronous optical networks into mainstream telephone systems, their high-speed transmission rates have been unable to accurately measure transmission signals using traditional test methods; and accurate measurements of sloshing in communication transmissions, It is a crucial issue in transmission. Since modulation domain analysis technology can perform 2 million times per second and 64,000 back-to-back frequency measurements, it is the only sloshing technology that can directly display changes over time. Furthermore, modulation domain analysis technology has its military uniqueness. The application, because it can measure and analyze rapidly changing frequency, time interval or phase relationship functions, modulation domain analysis technology can tune this signal to achieve the best performance of electronic equipment, in the case of radar, can be eliminated Its blind spots reduce the negative effects of target motion and improve the range and resolution of the radar system. In addition, the modulation domain analyzer is ideal for designing anti-lock braking systems, adjustable suspension systems, adaptive cruise control systems, collision avoidance radars, and a wide range of aerospace and defense systems. In summary, modulation domain analysis techniques can be used to accelerate the design and characterization of work and performance characteristics such as radar, electronic warfare, surveillance systems, spread spectrum communications, and more.
Nanjing Xinlian Electronic Equipment Co., Ltd. has developed a modulation domain analyzer from 10Hz to 2.5GHz, which has reached the level of similar foreign products and filled the domestic gap. It provides lower than foreign prices for electronic equipment and military equipment in the field of frequency hopping in China. /3 ~ 1/2 test means. In order to better meet the test needs, the next step will continue to develop higher frequency modulation domain analyzers.
Third, VXI bus technology has made significant progress VXI bus technology is a new bus technology that emerged at the end of the 20th century. It first appeared in the United States and was applied to the US Air Force electronic measuring instruments. The VXI bus combines the VME bus and GPIB to form a new standard. This modular instrument platform can meet the needs of future instrument applications, making electronic measuring instruments and systems a new era of development. The VXI bus is a new industry standard interface bus, a fully open, industry standard for multi-vendor instrumentation (modules, plug-in). There are three reasons for the introduction of this standard: one is to meet the requirements of technological development, the other is the lack of connectivity of multi-vendor instruments, and the third is the military's needs, and this is the most important aspect. What does the military demand? First, the portability of the military electronic measuring instrument war site, VXI can greatly reduce the size and weight of the device; Second, greatly improve the test speed, VXI can be 40 times faster than GPIB; Third, the adaptability of the test system, Flexibility is greatly improved; fourth is moderate price; fifth is conducive to giving full play to the role of computers.
This new bus standard, after being applied in the United States, is highly appreciated by all walks of life in China and has many researchers. After several years of exploration, China has made great progress and achieved specific applications in several aspects. For example, the VXI bus test software platform developed by the CAD Research Laboratory of the Institute of Testing Technology and Instrumentation of Chengdu University of Electronic Science and Technology is a major breakthrough in China's VXI test technology. Its main technical indicators are: 1. Hardware environment: embedded VXI controller, MXI controller and GPIB-VXI converter; GPIB interface such as NIPCI-GPIB, AT-GPIB/TNTHP82350/82341 and ES1400, as well as other necessary peripherals such as printer and UPS. 2. Software environment: Windows98 operating system; supports standard module driver (VISA32). 3. Software features: editable graphical programming environment; customizable virtual panel; rich data processing functions; open external program interface; simultaneous management of VXI, GPIB, 1553B, RS232 instruments and modules; . The research results have been applied to the "XXX model remote radar integrated test system", "fire control radar integrated test system" and various equipment VXI bus automatic test system.
Fourth, electronic test instruments to the millimeter wave to advance a large number of civilian and military electronic equipment are developing to the millimeter wave, especially in the military, its development is more rapid. It is expected that the signal environment of the electronic warfare system will reach 1 to 2 million pulses per second in the future, and the equipment system may have to execute several billion instructions. At present, the processing capability of integrated circuits cannot meet the requirements of military electronic equipment, which will affect the new generation. The operational capabilities of electronic warfare systems must develop ultra-high-speed integrated circuits (VHSICs). As a result, the test of integrated circuits will rise from hundreds of thousands of gates/chips to several million gates/chips, and the test difficulty will increase accordingly. In view of the fact that "the victory of modern warfare belongs to the party that can control the electromagnetic spectrum", since the 1980s, the United States, the Soviet Union and other countries have incorporated millimeter-wave technology into the new weapons and equipment development plan. Because microwave/millimeter-wave monolithic integrated circuits (MIMICs) can produce wideband receivers or wideband power components on a single substrate, they can produce small broadband with a weight of less than 25 lbs, a volume of less than 90 cubic inches, and an impact acceleration of 1000 g. Smart throwing jammers and multi-frequency phased array interference units. However, from several years of research, testing technology has become a bottleneck restricting the further development and improvement of MIMIC. Therefore, in recent years, our electronic instruments have paid attention to the development of millimeter waves. The AV3615 three-mm S-parameter test device and calibration component recently developed by the 41st Research Institute of the Ministry of Information Industry, together with the host, can perform amplitude and phase accuracy in the three-millimeter band; the millimeter-wave spread spectrum module of the spectrum analyzer and the institute The high-performance spectrum analyzers together form a system for spectrum analysis in the 9 kHz to 110 GHz band; the millimeter-wave power meter probe series enables direct measurement of microwave/millimeter wave power with the host. The EE3395 millimeter wave frequency counter developed by Nanjing Xinlian Electronic Equipment Co., Ltd. has a frequency measurement range of 10 Hz to 110 GHz. This product can be widely used in millimeter wave electronic countermeasure systems, satellite communication equipment, high precision radar and radio astronomy. .
V. Communication measuring instruments reach the high-tech level The development speed of the communication industry exceeds people's imagination, so we must adapt to the development of the communication industry and develop China's communication electronic measuring instruments at the fastest speed. In recent years, Chengdu Qianfeng Electronic Instrument Factory has completed the development of wireless paging detector, radio comprehensive tester and digital microwave communication tester. The 41st Research Institute of the Ministry of Information Industry has completed the error tester and digital transmission/data communication analysis. Instrument, No. 7 signaling tester, etc. These products have reached the international advanced level at the end of the 20th century.
Sixth, the rapid development of digital instruments In recent years, digital instruments are rapidly, such as digital oscilloscopes, digital modulation devices, digital functions / arbitrary waveform generators, digital audio and video measuring instruments, is to softwareize several hardware functions. The electronic measuring instrument, in addition to numerous basic measuring functions, can also carry out long-distance transmission and measurement, measure 23 video projects and 4 audio projects, and is now the best instrument selected by China's broadcasting and television system.
Others, such as in the field of optical communication testers, synthetic signal sources, VXI bus instrument modules, acoustic measuring instruments, etc., have developed many international products at the end of the twentieth century, but compared with the rapid development of information technology, China's electronic measuring instruments must aim at the development direction of the world's technology and make first-class electronic measuring instruments that are compatible with the development of information technology.
After more than 40 years of development, China's electronic measuring instruments have made great contributions to the development of China's national economy, science education, and especially the national defense military. With the trend of high-tech development in the world, China's electronic measuring instruments have also stepped into the road of high-tech development. Especially after the development during the Ninth Five-Year Plan period, China's electronic measuring instruments have made breakthroughs in several major scientific and technological fields. China's electronic measuring instruments have laid a good foundation for the world level.
