12 Measurement Procedures
The measurement procedures are as bellows:
<Conducted power measurement>
 For WWAN power measurement, use base station simulator to configure EUT WWAN transition in
conducted connection with RF cable, at maximum power in each supported wireless interface and
frequency band.
 Read the WWAN RF power level from the base station simulator.
 For WLAN/BT power measurement, use engineering software to configure EUT WLAN/BT continuously
transmission, at maximum RF power in each supported wireless interface and frequency band.
 Connect EUT RF port through RF cable to the power meter or spectrum analyzer, and measure WLAN/BT
output power.
<Conducted power measurement>
 Use base station simulator to configure EUT WWAN transmission in radiated connection, and engineering
software to configure EUT WLAN/BT continuously transmission, at maximum RF power, in the highest
power channel.
 Place the EUT in positions as Appendix B demonstrates.
 Set scan area, grid size and other setting on the DASY software.
 Measure SAR results for the highest power channel on each testing position.
 Find out the largest SAR result on these testing positions of each band.
 Measure SAR results for other channels in worst SAR testing position if the Reported SAR or highest
power channel is larger than 0.8 W/kg.
According to the test standard, the recommended procedure for assessing the peak spatial-average SAR value
consists of the following steps:
 Power reference measurement
 Area scan
 Zoom scan
 Power drift measurement
12.1 Spatial Peak SAR Evaluation
The procedure for spatial peak SAR evaluation has been implemented according to the test standard. It can be
conducted for 1g and 10g, as well as for user-specific masses. The DASY software includes all numerical
procedures necessary to evaluate the spatial peak SAR value.
The base for the evaluation is a “cube” measurement. The measured volume must include the 1g and 10 g
cubes with the highest averaged SAR values. For that purpose, the center of the measured volume is aligned to
the interpolated peak SAR value of a previously performed area scan.
The entire evaluation of the spatial peak values is performed within the post-processing engine (SEMCAD). The
system always gives the maximum values for 1g and 10g cubes. The algorithm to find the cube with highest
averaged SAR is divided into the following stages:
 Extraction of the measured data (grid and values) from the Zoom Scan.
 Calculation of the SAR value at every measurement point based on all stored data (A/D values and
measurement parameters).
 Generation of a high-resolution mesh within the measured volume.
 Interpolation of all measured values form the measurement grid to the high-resolution grid
 Extrapolation of the entire 3-D field distribution to the phantom surface over the distance from sensor to
surface
 Calculation of the averaged SAR within masses of 1g and 10g.
