1 Scope

This document specifies the electromagnetic compatibility (EMC) limits and performance criteria for wireless communication equipment and its auxiliary equipment, and describes the electromagnetic compatibility Sex measurement method. This document applies to all types of wireless communication equipment except broadcast receivers. Note. This document allows field testing of equipment for specific products that are not suitable for testing in a laboratory environment (for example, high-power radio transmitters). In this case, if there are no applicable field test standards and methods, the basic principles and limits used to evaluate the measurement methods of the equipment under test can be referred to. According to this document.
