Simultaneous Specific Absorption Rate Ratio Summation and Peak Location Separation
Exceeding simple SAR summation thresholds requires peak location separation ratios below 0.04 to avoid multi-thousand-dollar volumetric chamber testing.
DASY
Meaning
Precision robotic measurement platforms engineered for dosimetric and near-field radio frequency evaluations form benchmark compliance hardware in regulatory SAR testing. Recognized by global telecommunications authorities, DASY utilizes high-precision robotic arms and miniature E-field probes to scan wireless transmitting devices inside liquid-filled anatomical phantoms. Test routines execute automated grid scans to quantify localized energy absorption rates in living tissue models.
Qualification reports generated by these systems form the foundation of regulatory compliance filings worldwide.
Robotic Precision
Automated positional accuracy within sub-millimeter tolerances ensures reproducible field measurements across complex spatial geometries. Scanning modules within DASY execute coarse area scans followed by fine zoom scans around peak absorption regions. Robot arm movement avoids field distortion by utilizing non-metallic structural components near the phantom.
Tissue Simulation
Liquid phantom media match dielectric properties of human tissue across specific operational spectrum bands. Maintaining accurate fluid parameters in DASY test tanks prevents measurement drift during extended compliance runs.
Standard Compliance
Regulatory bodies mandate standardized test protocols to guarantee measurement repeatability between independent laboratories. Utilizing DASY ensures full compliance with international standards such as IEC 62209 and IEEE 1528. Advanced software algorithms perform phase reconstruction and field extrapolation from measured grid points.
Automated system checks verify probe calibration factors prior to initiating formal certification sequences.
