The Specific Absorption Rate (SAR) test is valued by governments and regulatory agencies of various countries. To enter smoothly into the international market, radio equipment must meet the SAR limit requirements. NG28 can provide professional Specific Absorption Rate (SAR) testing services.
Simulates the burst disturbances caused when the inductive load near or in the equipment's power grid is cut off.
NG28 Shenzhen Laboratory houses 8 electromagnetic shielding rooms and 4 anechoic chambers, allowing EMC conducted disturbance testing to be performed according to various internal standards and limits, among which are those of the European Union and the United States. Electronic and Electrical Products include household appliances, information technology equipment, lighting equipment, medical equipment, railway equipment, etc. Testing lead-time: 2-3 work days.
This test mainly simulates the phenomenon of grid voltage drops or even short interruptions caused by high-power equipment in AC and DC grids, to understand the performance stability of test equipment working under these voltage variations.
NG28 Shenzhen Laboratory houses 4 anechoic chambers, including two 3-antenna 3m semi-anechoic chambers, one 3m fully-anechoic chamber and one 10m anechoic chamber, allowing EMC radiated disturbance testing to be performed according to various internal standards and limits, among which are those of the European Union and the United States. Electronic and Electrical Products include household appliances, information technology equipment, lighting equipment, medical equipment, railway. Testing lead-time: 3-5 work days.
The Power frequency magnetic field immunity test mainly simulate the impact of magnetic field (such as those near larger transformers) formed by AC and DC power lines on the equipment undergoing testing.

Electrostatic discharge is to examine the resistance of the equipment when receiving direct discharge or electrostatic field interference from external static sources (such as human bodies or devices with electric charge).
The purpose of the radiated radio-frequency electromagnetic field immunity test is to investigate the anti-interference ability of the equipment against external electromagnetic field interferences.
The surge test is used to simulate the impact of the burst on the equipment from natural occurring lightning strike or connecting a large capacitive load to the grid.
NG28 has a professional and experienced technical team for radio frequency (RF) testing, who escorts manufacturers' wireless products smoothly into the international markets.
