cSAR3D Right Head

cSAR3D Right Head


cSAR3D Head is ideal for conducting high-precision SAR measurements of devices operated at the ear as required by IEC62209-1, IEEE 1528, FCC OET65, etc. The cSAR3D Head shape corresponds to the SAM head. cSAR3D performs fast (< 1 s) and repeatable (< 0.1 dB) measurements.

cSAR3D has been found by an independent laboratory to pass the strict validation requirements of IEC Draft 62209-3. A report of the validation results is available on request.
