Our Dosimetric Assessment System (DASY) is a robot-based high precision electromagnetic (EM) near-field scanning platform that was first introduced in 1994. Since then, more than 800 systems have been installed worldwide. DASY8, the 8th generation of DASY, is the most precise and advanced flexible scanning platform for testing compliance with any national (e.g., FCC, CENELEC) and international guidelines, standards, and regulations (e.g., IEC, IEEE, ICNIRP) and for a wide range of R&D measurement tasks related to EM exposure from 3 kHz to 110 GHz. Several application-specific hardware and software modules are available for DASY8.
The DASY8 Modules offer optimal solutions for any near-field tasks and are continuously updated to meet the latest regulatory and research requirements. they are tightly coupled with the co-developed premier simulation platform Sim4Life for advanced computational life science research and effective device development (ZMT Zurich MedTech AG, member of the Z43 alliance).
DASY83D is a full integration of the cSAR3D system with any of the DASY8 Modules, offering a combined system that seamlessly transitions from automated SAR pre-screening with cSAR3D to full evaluations using the gold standard DASY8.
DASY8 Module SAR / APD is optimized for demonstration of compliance with local and whole-body specific absorption rate (SAR) limits from 4 MHz to 10 GHz and the absorbed power density (APD) from 6 GHz to 10 GHz based on SAR measurements. The module scans the field in the entire or in a sub-volume of a phantom filled with tissue simulating liquid and determines the peak spatial SAR directly without any approximation. It is the most accurate SAR tool available on the market and considered as the gold standard in compliance testing.
DASY8 Module SAR / APD is compatible with:
DASY8 Module APD is optimized for demonstration of compliance with the absorbed power denisty limits from 10 to 45 GHz
DASY8 Module mmWave is optimized for demonstration of compliance with the incident PD limits from 6 to 110 GHz using the smallest pseudo-vector electric (E-) field probe. The module scans the magnitude of the field in planes (closest plane as close as 2 mm from the device) and determines the phase using our powerful reconstruction algorithm. Two options are available: the Forward Transform Evaluation (FTE) option to determine the field in the entire volume above the scanned plane, and the Maximum Exposure Optimizer (MEO) option to evaluate the maximum of beam-forming antennas. The measured files can also be directly imported in Sim4Life to perform additional advanced Use Case evaluations.

DASY8 Module WPT is optimized for demonstration of compliance of magnetic field sources (e.g., wireless power transfer (WPT)) operating from 3 kHz to 4 MHz with reference levels limits and basic restrictions. The module performs a volume scan of the magnetic (H-) field in free space and computes the induced field using the integrated Quasi-Static EM solver (P-EM-QS) component of the Sim4Life simulation platform. The exported file Sim4Life-WPT is fully compatible with Sim4Life for any further Use Case investigation.
DASY8 Module WPT is compatible with:
DASY8 Module HAC is optimized for effective demonstration of hearing aid compatibility (HAC) with IEEE C63.19-2019.

DASY8 Module R&D is optimized for performing user-specific scans with SPEAG's own as well as third-party probes. Various Jupyter Notebook-based graphical user interfaces are made available for the most common tasks. The extensive command set of the application programming interface enables the user to perform and automate field scans. Additional customized Jupyter Notebook-based procedures are available on request.
