NATA RF DOSIMETRY TESTING OF MOBILE PHONES

Now available in Australia

EMC Technologies Pty Ltd has extended the scope of their AS/NZS2772 NATA accreditation for Electromagnetic Radiation (EMR) measurements, to include Specific Absorption Rate (SAR) evaluation of handheld or body mounted RF transmitting devices as required by the EMR Framework.

The scope of the EMR Framework includes Mobile Telecommunication Equipment (MTE) and mobile phone base stations such as AMPS, GSM, CDMA, DECT, CT2/CT3, PHS and spread spectrum devices. These devices must be evaluated against the ACA mandatory human exposure standard, which sets basic restrictions for the SAR by humans. SAR is a dosimetric quantity and is defined as the rate at which RF energy is absorbed per unit mass. RF dosimetry is the quantification of the magnitude and distribution of absorbed electromagnetic energy within human and biological objects that are exposed to EMR.

A precision RF Dosimetric Assessment System (DASY) developed by the Swiss Federal Institute of Technology (ETH) is used to perform precise SAR measurements in the extreme near-field. It consists of a computer controlled, high precision robotics system, robot controller, extreme near-field probes, probe alignment sensor, and the generic twin phantom containing the brain equivalent material. The six axis robot precisely positions the probe at the points of maximum electromagnetic field.

The system also provides precise measurements in free space as well as inside tissue simulating liquids and cadavers. The flexible data evaluation and visualization capabilities allow electromagnetic design and performance evaluations in other applications including SAR optimization, EMI, EMC, PCB, wireless communications, biomedical applications and industrial RF machines.

The unique NATA accreditation includes the ACA SAR mandatory standard, as well as the European standard ES 59005 and USA regulation FCC OET 65.
