DASY8 Module WPT - MAGPy

DASY8 Module WPT is composed of the isotropic probe MAGPy-8H3D+E3D Version 2, the reference probe (MAGPy-RAφ), and the data acquisition system (MAGPy-DAS) mounted to the DASY8 robot via the emergency stop (MAGPy-ES). The induced electric (E-) fields and specific absorption rate (SAR) are assessed with Sim4Life’s Quasi-Static EM Solver (P-EM-QS) using only the measured data. At each probe location, eight isotropic H-field values are acquired in parallel. The dedicated graphical user interface (GUI) fully automates the testing workflow.
