★ Introduction to SAR test


SAR is known as Specific Absorption Rate, which is generally called Electromagnetic Wave Absorption Ratio or Specific Absorption Rate. Is the mobile phone or wireless products, the electromagnetic wave energy absorption ratio, which is defined as: the role of the external electromagnetic field, the body will produce induced electromagnetic field. As the body of various organs are depleted medium, so the body of electromagnetic fields will produce current, resulting in absorption and dissipation of electromagnetic energy. Biological technology commonly used in SAR to characterize this physical process. The significance of SAR is the unit power of the human body absorbed or consumed by the electromagnetic power, in W / kg.

★ Depp is the introduction of SAR laboratory capability

De Puhua SAR Labs supports SAR testing of mobile devices such as mobile phones, data cards, tablet PCs, walkie-talkies and other mobile devices. Test frequency range 300MHz-6GHz, including 2G, 3G, 4G, WIFI and other communication standards.

★ Introduction to SAR laboratory equipment

The latest introduction of the French SATIMO SAR test system, the test system to meet the YD / T 1644, EN 62209-1, FCC OET Bulletin 65 and other domestic and foreign standards. The SAR test system supports dual head table options, with fast test speed, equipment, high stability.
