Picture showing SPEAG’s DASY6 Module SAR. It’s successor, DASY8 Module SAR / APD, will be released in February 2021.
DASY8 Module SAR / APD is composed of hardware and software components 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 MHz to 30 GHz in full accordance with all national and international standards and regulations. Due to its reliability and proven accuracy it is considered the gold standard in compliance testing.
DASY8 Module SAR / APD is composed of an isotropic dosimetric probe (SAR, APD) mounted to the precision robot TX2 allowing to scan the field inside anthropomorphic phantoms filled with tissue-simulating liquids. The probes are miniaturized, sensitive, isotopic, linear, stable, and calibrated with precise boundary compensation. The spatial precision of positioning the probe inside the phantom is better than 0.2 mm. The scanning is optimized and adaptive to the induced field. The peak spatial SAR is determined without reconstruction.
The intuitive graphical user interface has been designed to follow the workflow described in SAR compliance standards, from generating the project file to reporting the measurements. Base station simulators are integrated allowing automated testing.
An advanced application programming interface (API) allows for development of customized testing strategies.
|Applications||SAR compliance testing of any wireless devices|
The basic components of DASY8 Module SAR / APD are:
|Probes||EX3DVx – Smallest isotropic dosimetric probe for high precision SAR measurements in any exposure scenario (e.g., very strong gradient fields); the only probe that enables compliance testing for frequencies up to 10 GHz with a precision of better than 30%
DASY8 Module SAR / APD is fully compatible with the following SAR phantoms:
|Tissue Simulating Liquids||DASY8 Module SAR / APD is also compatible with SPEAG's tissue simulating liquids:|
MAIA – (Modulation and Audio Interference Analyzer) – Modulation analysis interface to validate the communication settings of the wireless device signal; enables the determination of the linearization parameters
ANT – Ultra-wideband omnidirectional antenna (695 – 6000 MHz) that connects to base station simulators for automated call handling of the wireless device
POWERSOURCE1 – USB powered radiofrequency (RF) source optimized to feed continuous wave (CW) signals to system check sources
|System Check / Verification||
SPEAG offers a variety of verification sources to be used for system check prior to SAR testing of unknown devices.
Confined Loop Antennas (CLA) for frequencies from 6 MHz up to 220 MHz:
Dipoles for frequencies from 300 MHz up to 10 GHz:
|Base Station Simulators||
DASY8 Module SAR / APD inherently supports base-station simulators. The following base-station simulators are currently integrated:
The API Option enables the further automation of SAR compliance measurement workflows via HTTP commands. Typical use cases are:
|Calibration||DASY8 supports the novel Sensor Model Calibration (SMC) method, Probe Modulation Response (PMR) calibration, and standard linearization for calibration of pulsed signals.|
DASY8 Module SAR / APD is compatible with:
Smart Zoom Scan
The Smart Zoom Scan is a new feature to be used in accordance with IEC 62209-2:2019 Amendment 1 on grid resolution. Measurement repetitions can be very time consuming; the Smart Zoom Scan adjusts the grid steps automatically. The procedure is fully automated and integrated in the measurement workflow as shown in this tutorial video.
DASY8 features automated Time-Averaged SAR measurements for devices that monitor and control the time-averaged transmitted power in real-time over the period defined in the applicable standards. A detailed measurement procedure is described in this application note and tutorial video.
Measurements in Specific Phantoms (SAM Face-Down, SAM Head-Stand, SAM Chin-20 Right/Left, and Wrist Phantom) are available in DASY8 to ease SAR compliance testing of wireless devices not operating around the ear-mouth line area or mounted on the torso. The procedure and validation for measurements in specific phantoms are described in this application note and in this tutorial video.
The API enables quicker, easier, and more reliable measurements via full automation of the measurement workflow
