Just one month after the successful launch of cDASY6 Module SAR V6.12 for automated measurements with the “API Option”, SPEAG is yet again simplifying specific absorption rate (SAR) compliance testing by introducing an adaptive zoom scan. Thanks to the new Smart Zoom Scan feature, measurements are now:
The new release also features additional application programming interface (API) commands.
Modern mobile devices tested at a distance of less than 5 mm from the phantom shell often generate SAR distributions with a very localized absorptions. The frequency-based minimal grid settings as defined in the international standards are not always sufficient to ensure accurate post-processing. To resolve this issue, knowing that the standardization process is slow, SPEAG recommended more than 10 years ago that DASY users apply more restrictive grid settings and the use of the high-resolution EXD3Vx probe for very localized exposures. In addition, the International Electrotechnical Commission (IEC) published an amendment (IEC 62209-2 Amendment 1) in 2019 requiring that zoom scans must meet the following two criteria:
National regulators like the US Federal Communications Commission (FCC) and Innovation, Science and Economic Development (ISED) Canada rapidly adopted the IEC 62209-2 Amendment 1. SPEAG introduced already in 2017 a warning message in the DASY6 software to flag cases in which the two criteria are not fulfilled. In such cases, the operator would be directed to re-measure the complete zoom scan with finer grid settings.
In-depth discussions with our users revealed that having to perform measurements with very fine grids – or having to repeat measurements &ndash to ensure to meet IEC requirements is very time consuming.
To overcome this problem, SPEAG is now introducing the Smart Zoom Scan feature in cDASY Module SAR V6.14:
The adaptive scanning leads to:

In response to feedback from our first cDASY6 API users, we have extended the available set of commands in cDASY6 Module SAR V6.14 to make it possible to:
