The radio interference of antennas and receiving systems is based on the "antenna" (invisible antenna-wireless receiving system) as the entry point to establish antennas and radio Electromagnetic compatibility standards for receiving systems, covering antennas, measurement sites and wireless receiving systems. GB/T (Z) 40602 "Radio Interference from Antennas and Receiving Systems" is intended to consist of four parts.

1.Indoor far-field measurement method for basic measurement of antenna pattern. The purpose is to specify the antenna radiation pattern in micro Measurement method for equal elevated far fields in anechoic chambers.

2.Basic measurement method of indoor plane near-field measurement of high-gain antenna pattern. The purpose is to specify high gain antennas Planar near-field scanning method is a method for measuring antenna pattern in a microwave anechoic chamber.

3.Site measurement and compression site performance confirmation method. The purpose is to specify the compact field shielding effectiveness and static field radiation characteristics. properties, phase characteristics and cross-polarization performance.

4.Test methods for electromagnetic compatibility of electronic equipment with integrated wireless modules in wireless receiving systems. The purpose is to provide for industrial use Electromagnetic compatibility test requirements and test methods for integrated wireless module electronic equipment such as industrial, scientific, medical, automotive, and household appliances. GB/T (Z) 40602 "Radio Interference of Antennas and Receiving Systems" and GB/T 38889 together constitute the radio interference of antennas and receiving systems. Line interference standard system.

1 Scope

This document sets out the electromagnetic compatibility test method for electronic equipment that has a radio module built into it, as part 4 of the GB/Z 40602 series on antennas and receiving systems. Almost every product now contains a radio it was not designed around - a Wi-Fi module in an appliance, a Bluetooth chip in a tool, a cellular modem in a meter. Testing such a product is awkward because the radio is both the victim of interference and a source of it, and the classic EMC procedures assume it is one or the other. This part addresses exactly that case. Issued on 7 September 2023 by SAMR and SAC as a guiding technical document, in force from the same day. Relevant to any manufacturer putting a connected product through Chinese EMC testing.

This document specifies the electromagnetic compatibility test method for electronic and electrical equipment with integrated wireless modules, including an overview, electromagnetic compatibility test evaluation guidelines guidelines and testing requirements. This document applies to electronic and electrical equipment that integrates wireless module devices to achieve wireless functions in residential, commercial and industrial environments. The test methods specified in this document are used together with the electromagnetic compatibility standards for electronic and electrical equipment. The relevant electronic and electrical equipment includes but does not Limited to.

---Information technology equipment, multimedia equipment and receivers;

---Industrial, scientific and medical equipment;

---Household appliances, power tools and similar appliances;

---Electrical lighting and similar equipment;

---Automobiles, vehicle components and equipment, etc.
