Maximum Permissible Exposure (MPE) evaluations 

These evaluations are performed on radiating structures that would be intended to be used at distances >20cm from the end-user.    

Regulatory compliance testing

We have the accreditations and experience to perform SAR testing up to 6GHz for various countries.

Automated Test Systems

Our SAR facilities are fully equipped with Schmid & Partner Engineering AG (SPEAG™) DASY systems utilizing an RX 90 robotic arm for extended reaching capabilities.

Extended Capabilities 

Our DASY systems have multiple twin SAM phantoms and planar phantoms which allows for quick testing turnaround times. The DASY is capable of evaluating products for SAR to all the global SAR standards for both head and body-worn devices.

What is SAR testing?

Specific Absorption Rate (SAR) testing is the radiofrequency (RF) dosimetry quantification of the magnitude and distribution of absorbed electromagnetic energy within biological objects that are exposed to RF fields.

These levels are expressed as watts per kilogram (W/kg). International regulatory bodies are requiring SAR evaluations for most portable and mobile wireless technologies.

Parameters that can affect SAR include:

• Types of radio service (cellular, PCS, LMR, WLAN, etc.)
• Types of modulations (CDMA, GMSK, TDMA, AMPS, etc.)
• Physical orientation to person (held-to-ear, held-to-face, belt-clip, lap-held, etc.)
• RF power level (in Watts or mW)
• Changes to transmitter, antenna (extracted/retracted) or accessories (clips, batteries, etc.)

The FCC classifies a wide range of standalone independently-operated portable transmitters as being potential candidates for SAR testing. Laptop computers, for example, may require SAR testing. Handsets, pagers, and other devices that are worn on a belt can also require SAR testing. When portable transmitter antennas and radiating structures are less than 20 cm from persons, except extremities (hands, wrist, feet and ankles), and depending on the device’s frequency and threshold levels, SAR testing may be required.
