Problems solved by technology

In order to ensure the accuracy and reliability of the electromagnetic radiation analyzer, it is necessary to measure and evaluate the electromagnetic radiation analyzer. The current international standards and domestic standards used in the measurement and evaluation have a common disadvantage: continuous wave electromagnetic fields are used in the measurement and evaluation process. The process is necessary, but not sufficient, because the characteristics of the electromagnetic field in the actual electromagnetic environment are: multi-band composite electromagnetic fields, including broadband vector modulated electromagnetic fields, some of which have the characteristics of pulse time slots
