Abstract
The invention relates to a method for measuring the specific absorption rate SAR of a mobile device under test DUT enabled for a combined LTE RF and 5G RF transmission, the method comprising the following steps: a.) Providing a mobile device under test DUT operable in LTE RF and 5G standard, b.) Setting the DUT in a mode to transmit with maximum power level according to the 5G standard, and at the same time transmitting with lower power level of LTE RF standard, c.) Performing a SAR scan and measuring the 5G signal, without taking into account any contribution from the LTE RF signal, d.) Setting the DUT in a mode to transmit with maximum power at maximum power in LTE RF standard, without transmitting according to the 5G standard, e.) Performing a SAR scan and measuring the LTE RF standard signal, f.) Combining the results of step c.) and e.) in order obtain a combined SAR value.
