Introduction and application of vector signal analyzer measurement and test solutions

The term "measurement" became a professional term in China in 1953, replacing the ancient "weights and measures". According to the "International Basic Terms of Metrology" jointly formulated by the International Bureau of Weights and Measures (BIPM), the International Electrotechnical Commission (IEC), the International Organization for Standardization (ISO) and the International Organization of Legal Metrology (OIML), metrology is defined as a science related to measurement, which is a science that ensures the unification of measurement units and the accuracy and reliability of measurement values.

Radio metrology, as an important field of metrology, has developed rapidly in the past. Radio metrology testing has been recognized as a subject closely related to various industries and is receiving more and more attention. In particular, microwave and millimeter wave measurement, real-time online measurement, on-site measurement, comprehensive parameter measurement, various digital modulations, and complex modulation metrology testing have become new topics in modern metrology testing.
