Time-Averaged SAR Testing without Special Tools » SPEAG, Schmid & Partner Engineering AG
Summary
SPEAG worked closely with chip manufacturers and regulators to provide a solution for testing devices with DASY8/6 that feature dynamic power control – exposure time averaging (DPC-ETA) algorithms without manufacturer tools. Efficient demonstration of compliance with exposure limits typically requires special tools provided by the manufacturer to set up the devices in specific test configurations. One of these features is the so-called dynamic power control and exposure time-averaging algorithm (DPC-ETA), which ensures that the time-averaged specific absorption rate (TAS) values are not exceeded, even if exposure is larger over a short period of time. Together with chip manufacturers and regulators, SPEAG has developed a method to evaluate DPC-ETA-enabled phones with DASY8/6. A user video that follows the instructions in the application note shows how easy yet accurate TAS evaluations are.
