DASY8 Module APD is the first system worldwide for demonstration of compliance with absorbed power density (APD) limits at frequencies from 10 – 45 GHz in full accordance with all national and international standards and regulations.
DASY8 Module APD is composed of a pseudo-vector APD probe (EUAPDVx) mounted to the precision robot TX2, which allows the fields inside frequency-specific APD phantoms – filled with liquids that simulate reflection/transmission of the human skin – to be scanned. The probes are miniaturized, sensitive, highly linear, and calibrated. The relative spatial precision used to position the probe inside the phantom is better than 0.1 mm. The scanning is optimized and is adaptive to the induced field. The peak spatial APD is determined by reconstruction. The advanced software allows for the evaluation of any transmitter, including multiple-input multiple-output (MIMO) devices.
An advanced application programming interface (API) allows for the development of customized testing strategies.
|Evaluation of the compliance of any wireless device with APD safety guidelines and regulatory requirements at frequencies of 10 – 45 GHz.
EUAPDVx – Designed for precise near-field measurements in the mm-wave range. The specifications are:
The APD phantoms, together with the skin-simulating liquids, reliably emulate the absorption and reflection characteristics of human skin.
DASY8 Module APD supports the following APD phantoms:
Additional phantoms are being developed and will be released in 4Q2024 to cover the full 10 – 45 GHz frequency range.
|Skin Simulating Liquids
DASY8 Module APD supports the following skin-simulating liquids (SSL):
Additional skin-simulated liquids are being developed and will be released in 4Q2024 to cover the full 10 GHz – 45 GHz frequency range.
Dielectric properties of the skin-simulating liquids can be measured with a DAK 1.2E.
MD4APDVx - Ensures accurate positioning of smartphones under the APD phantom.
MDP4APDVx - Mounting device platform to easily position the MD4APDVx under the APD phantom.
|System Check / Verification
DASY8 Module APD is compatible with the Verification Source 30 GHz.
Additional verification sources are being developed and will be released in 4Q2024 to cover the full 10 – 45 GHz frequency range.
DASY8 Module APD offers the following features:
The API Option enables further automation of APD compliance measurement workflows via HTTP commands.
Typical use cases are:
The API is compatible with any programming language supporting HTTP requests. It is available as a licensed option.
|DASY8 Module APD supports the Sensor Model Calibration (SMC) and standard linearization for pulsed signals.
DASY8 Module APD enables measurement of the absorbed power density (ICNIRP2020) and epithelial power density (IEEE C95.1-2019).
It is fully compatible with the GB 21288-2022. the latest draft of the IEC/IEEE TR APD and other upcoming national regulations.
Reliable and Repeatable
The only solution that accounts for backscattering, standing waves between transmitter and body, and absorption of reactive near-field components
The method is optimized to assess devices featuring transmitters with massive multiple-input multiple-output (MaMIMO) elements
As the method directly measures the APD, it is more reliable and provides better repeatability than any other method.
