It has developed a series of high-performance, easy-to-use test and measurement instruments and laboratory solutions for teachers and students in colleges and universities. Designing technology and expanding innovative R&D capabilities provide the best tools.
Q: What are the key roles of Tektronix in supporting the National Undergraduate Electronic Competition?
A: The annual electronic competition for undergraduate students is also an educational industry event in which Tektronix is mainly involved in support. With the increasing difficulty of the topic, and the further integration of the direction of the problem and the actual application of the industry, more high-performance, high-bandwidth test instruments are available. The use of oscilloscopes as an example, 500MHz bandwidth oscilloscope has become the necessary equipment for the evaluation of the electric game.
From provincial to national competitions, Tektronix provides a large number of evaluation instruments and personnel support to help conduct on-site testing and use high-reliability and high-precision equipment to ensure the smooth holding of undergraduate electronic competitions. Take the 2017 national competition as an example, Tektronix provides More than 30 sets of MDO3000/4000 oscilloscopes, as well as general-purpose signal generators, RF signal generators, power analyzers, spectrum analyzers, network analyzers, multimeters, etc., have a total of more than 200 units worth nearly 10 million yuan. The competition evaluation team highly praised the professional.
In the final round of the 2017 National Games, question F asked the students to produce AM demodulation circuits. The standard evaluation requires that the input signal frequency range be 250 to 300 MHz. In the final stage, in order to further evaluate the circuit performance of each team, the evaluation experts requested further improvement. Check the signal frequency and check the demodulation limit of each team. The highest demodulation frequency of a group of students reaches 1.2GHz, which is the first place in the game. The use of higher-performance and higher-accuracy test instruments has become the secret of the winning team. With the support of these high quality test instruments, the students brought their professional director to the best position and achieved excellent rankings.
Q: What innovations have Tektronix made in the education industry?
A: With the reform of the education industry, more and more universities are trying to incorporate more innovations in basic education to meet the needs of industry and employers for new engineering talents. The Ministry of Education has also proposed new engineering concepts. Cultivate more talents with dual-creating ability. Each school started reform of teaching courses and experimental courses under the call of the Ministry of Education. It is hoped that more relevant content of actual industry application will be brought into the university classroom to allow students to experiment in undergraduate courses. The room can be exposed to more practical applications, improve hands-on capabilities, and lay a good foundation for the future as soon as possible.
Tektronix is the only international electronic test instrument manufacturer with profound accumulation in the basic education industry and industry frontier. Whether in manufacturing, high-end R&D or cutting-edge scientific research fields, it has accumulated a wealth of test experience. Therefore, Tektronix is also trying to help college experiments. The room builds richer curriculum content and helps lab teachers graft cutting-edge industrial application knowledge into teaching laboratories.
Q: Are there specific cases that can be shared for reference by more universities?
Take power electronics laboratory teaching reform as an example. We divide the power electronics industry according to the industrial structure and decompose it from four experimental platforms, including power device testing, power module debugging, power supply testing and new energy testing.
Each experimental platform is designed with several experimental contents that are closely integrated with the actual application, such as how to design and test the LED driver circuit in the power supply unit test, how to evaluate the performance of the driver circuit, and the corresponding national test standards. Understand the industrial background and development direction in the experimental course, familiarize with the industry characteristics and test requirements, and master the relevant research and development and testing methods. Provide ideas for the reform of the teaching content of professional experimental courses.
Q: The communications industry is changing with each passing day. How can we advance the progress of colleges and universities in the field of radio frequency communications?
The radio frequency communication laboratory is another attempt direction of Tektronix. The traditional teaching of radio frequency communication is relatively abstract. After studying a large number of related courses, it is still difficult for students to establish the concept of a complete communication system. It is impossible to understand the practical application of each course. The role of this has led to a decline in students’ interest in learning. In addition, in the original communication course experiment, the experiment frequency was generally too low, and the experiment content was also very old. Today, digital modulation is widely used today and traditional FM is still repeated. AM experiment content, which is very unfavorable for students to go to work and adapt to job content. To improve this situation, Tektronix and third-party partners will bring software radio technology into the classroom, from the perspective of a complete communication system. Students build concepts, understand technology applications, and master techniques and capabilities for RF communication testing.
In the software radio-based teaching content, digital signal processing, communication principles, and radio frequency microwave content can be combined with experiments to allow students to quickly build a communication prototype in the laboratory, verifying different modulation methods, and setting different radio frequency parameters. Under the communication system performance. In the traditional software radio based on the addition of a large number of RF test points to help students understand the role of RF devices, understand the meaning of RF performance indicators.
Through the exchange and improvement of these laboratory programs, the close cooperation between Tektronix and the colleges and universities learns from each other and learns from each other, combining the rich accumulation of Tektronix in the industry and the rich experience of the school in teaching, for the future. Teaching reforms provide more effective means.
