Description

technical field [0001] The invention relates to the technical field of electronic measurement, in particular to an experimental training system integrating theory and practice of electronic measurement technology. Background technique [0002] At present, the country is vigorously developing higher vocational education, and is constantly exploring the teaching content, teaching mode, teaching method and teaching means suitable for vocational education. In this environment, many colleges and universities have made reforms to the original courses, and the course of electronic measurement technology is no exception. Many schools have carried out teaching reforms on the integration of theory and practice for this course, and compiled corresponding project-based teaching materials. ; Many schools have also built new electronic measurement laboratories for this purpose, generally including digital storage oscilloscopes, mixed-signal digital oscilloscopes (with logic analyzers), ar...
