Course Background Introduction
In recent years, with the rapid development of wireless communication technology in China, wireless communication has become a highly advanced technology industry with a huge output value and a large number of practitioners. Hardware, as an indispensable component in the research, manufacturing, and construction of wireless communication technology, is essential for testing to verify its performance and quality. To meet the needs of personnel involved in the research, debugging, testing, and engineering construction of wireless communication hardware, as well as learners in related fields, the “Dr. T Team”, as a pioneer in the domestic testing field, has specially produced a series of microwave testing technology courses.
Currently, the learning materials for RF microwave measurement found through the Internet are usually provided by instrument manufacturers and are relatively fragmented.“Dr. T’s Measurement” is the first systematic video teaching course in the RF industry created by a front-line engineering team based on practical engineering applications, greatly enriching the learning content in the field of microwave testing and measurement.The video explanation format, combined with supporting course handouts and mutual assistance guidance in WeChat groups, allows users in the RF industry to systematically and efficiently master microwave measurement knowledge and key issues in engineering practice, while also providing a certain knowledge reserve and industry application guidance for users engaged in this industry.
This course is based on our testing team’s years of experience in microwave testing and measurement, taking the engineering application perspective as an opportunity, starting from the basics of microwave measurement, and distilling commonly used foundational content in microwave testing technology in a clear and accessible manner; Chapters 2 to 7 provide detailed explanations of various instruments widely used in microwave measurement, including vector network analyzers, signal generators, spectrum analyzers, power meters, oscilloscopes, noise figure testers, digital multimeters, and desktop power supplies, starting with an overview and combining relevant theories with engineering practice applications, explaining the working principles, usage methods, and precautions of measuring instruments; finally, using examples of passive devices, amplifying devices, and frequency conversion devices, it details the preparatory work before testing, the correct selection of testing methods, operational steps, and the processing of measurement results and uncertainty analysis.
This course is suitable for:
1. Students and teachers in electronic engineering, communication engineering, electronic measurement, and instrumentation at science and engineering universities;
2. Individuals with no background who are about to engage in wireless communication research and development, microwave measurement, microwave debugging, instrument calibration, etc.;
3. Engineers working in microwave testing and measurement-related fields;
What help does this course provide to students:
1. Master the basic knowledge related to testing and measurement;
2. Quickly transform theoretical knowledge into engineering application capabilities, laying a foundation for future work and study;
3. Quickly and proficiently master the basic principles, foundational operations, usage methods, and precautions of various testing instruments, thus facilitating measurement work;
4. Through a series of testing examples, enable students to systematically and effectively characterize the performance characteristics of the tested devices;
5. Paid users can watch the complete video course online, and also receive answers from the instructor (public questions allowed) and download course handouts and materials. Other users can join the discussion group to discuss and learn together.Course Instructor Team Introduction:The Dr. T team consists of three professionals with over ten years of experience in the testing and measurement field; they have long been engaged in the testing and measurement industry, accumulating rich testing experience; they have edited and participated in relevant measurement standards and contributed to the research of some testing methods, filling several gaps in this field; the team is also skilled in writing testing mini-programs and building automated testing systems to improve testing efficiency; the team is committed to researching and developing new technologies and fields in testing to meet the growing testing demands by continuously enhancing the team’s technical capabilities.This course is divided into eight chapters, totaling 20 lectures, and has now been updated to the 12th lecture.
