10 SAR System Verification
Each DASY system is equipped with one or more system validation kits. These units, together with the
predefined measurement procedures within the DASY software, enable the user to conduct the system
performance check and system validation. System validation kit includes a dipole, tripod holder to fix it
underneath the flat phantom and a corresponding distance holder.
Purpose of System Performance check
The system performance check verifies that the system operates within its specifications. System and
operator errors can be detected and corrected. It is recommended that the system performance check be
performed prior to any usage of the system in order to guarantee reproducible results. The system
performance check uses normal SAR measurements in a simplified setup with a well characterized source.
This setup was selected to give a high sensitivity to all parameters that might fail or vary over time. The
system check does not intend to replace the calibration of the components, but indicates situations where
the system uncertainty is exceeded due to drift or failure.
System Setup
In the simplified setup for system evaluation, the EUT is replaced by a calibrated dipole and the power
source is replaced by a continuous wave that comes from a signal generator. The calibrated dipole must be
placed beneath the flat phantom section of the SAM twin phantom with the correct distance holder. The
distance holder should touch the phantom surface with a light pressure at the reference marking and be
oriented parallel to the long side of the phantom. The equipment setup is shown below:
