iSAR² (Head & Flat) represents the next generation of immediate SAR scanners from SPEAG. The iSAR² systems are ultra-fast scanners that evaluate the overall RF performance, SAR pattern and peak spatial SAR for 1 gram and 10 gram averaging volumes within less than 3 seconds. iSAR Head and iSAR Flat evaluate devices operated at the ear and on the body respectively. Both systems provide reliable, repeatable performance and support automated testing.

Application – Production Line Testing

iSAR² complies with the requirements of production line testing. All tests are conducted under typical loaded conditions when operated close to the body and can be evaluated with respect to a reference phone. It provides a host of new advantages instantly (<3 s) and reliably (<0.1 dB):

• detects non-compliance with safety limits
• detects deviations from target antenna input power
• detects any deviation in RF performance compared to a reference phone (e.g., antenna matching, poor contacts, shielding problems)

Application – Prototype Testing

Provides total confidence automated testing in combination with a tester, e.g., CMU200:

• measurement and visualization of the complete absorption pattern 4 mm below the surface
• visualization of differences in the absorption pattern between prototypes
• evaluation of the effect of small design modifications on RF performance, such as the different quality of interconnections, shielding, antenna feeds, etc.
• spatial peak SAR (deviation from DASY5 evaluation of less than 0.5 dB for the majority of transmitters)
• repeatability of less than 0.1 dB using the combiner feature (the combiner feature combines numerous measurements by registration to substantially increase the resolution and reduce the isotropy and calibration uncertainty.

ISO/IEC 17025 calibration service available.
