SYSTEM PERFORMANCE CHECK
The system performance check is performed prior to any usage of the system in order to guarantee
reproducible results. The system performance check verifies that the system operates within its
specifications of
reproducible results. The system performance check verifies that the system operates within its
specifications of
±10%.
System Performance Check Measurement Conditions
•
The measurements were performed in the flat section of the SAM twin phantom filled with Body
simulating liquid of the following parameters.
• The DASY4 system with an Isotropic E-Field Probe EX3DV3-SN: 3531 was used for the
measurements.
• The dipole was mounted on the small tripod so that the dipole feed point was positioned below the
center marking of the flat phantom section and the dipole was oriented parallel to the body axis (the
long side of the phantom). The standard measuring distance was 10 mm (above 1 GHz) and
15 mm (below 1 GHz) from dipole center to the simulating liquid surface.
long side of the phantom). The standard measuring distance was 10 mm (above 1 GHz) and
15 mm (below 1 GHz) from dipole center to the simulating liquid surface.
• The coarse grid with a grid spacing of 15 mm was aligned with the dipole.
For 5 GHz band - The coarse grid with a grid spacing of 10 mm was aligned with the dipole.
• Special 5 x 5 x 7 fine cube was chosen for cube integration(dx=dy=7.5mm; dz=5mm).
For 5 GHz band - Special 8x8x8 fine cube was chosen for cube integration(dx=dy=4.3mm; dz=3mm)
• Distance between probe sensors and phantom surface was set to 4 mm.
For 5 GHz band - Distance between probe sensors and phantom surface was set to 2.0mm
• The dipole input power (forward power) was 250 mW±3%.
• The results are normalized to 1 W input power.
Reference SAR Values for body-tissue
In the table below, the numerical reference SAR values of a SPEAG validation dipoles placed below the
flat phantom filled with body-tissue simulating liquid are given. The reference SAR values were
calculated using the finite-difference time-domain method and the geometry parameters.
