DASY8/6 Module SAR V16.4: Enable Multi-TX Evaluations for Devices with TAS

Most modern smartphones feature dynamic power control exposure time averaging (DPC-ETA) and the ability to transmit on different frequency bands simultaneously. SPEAG has worked closely with regulators to release a measurement procedure in Module SAR V16.4 that allows such devices to be tested as part of market surveillance – without the use of manufacturer tools. Furthermore, new features have been integrated that make testing even easier.

Updated TAS (Time-Averaged SAR) Procedure for Market Surveillance

Specific absorption rate (SAR) testing for compliance with exposure limits is often performed using specialized tools provided by the device manufacturer to configure the device under test (DUT) in the desired configuration. In most cases, market surveillance is performed on samples purchased on the market without using test modes.

SPEAG released the first version of the “Time-Averaged SAR Measurements for Market Surveillance” application note in April 2022. It described how to measure SAR for devices with power-monitoring algorithms in the context of market surveillance.

In light of the recent developments in mobile phone technologies, SPEAG was asked to provide easy-to-use solutions for configurations with multiple transmitters emitting simultaneously with power monitoring enabled. The resulting procedure is available in the updated version of the application note.

At the same time, SPEAG improved the time-averaged SAR (TAS) scan display in V16.4: the instantaneous peak spatial SAR averaged over 10g of tissue (psSAR1g/10g) can now be visualized and exported.

Improved User Experience

In response to the valuable feedback from our customers, DASY8/6 Module SAR V16.4 introduces several notable enhancements, which are listed below:

  • The pEind,inst (i.e., the maximum instantaneous electric (E-)field value at the phantom surface) required for compliance testing against the ISED SPR-002 Issue 2 is now computed automatically;
  • The multimeter view has been fully redesigned and allows visualization of SAR, E-field, and measured voltage values;
  • The project files can be compressed when saved, resulting in a 4 to 20 times smaller file size. This feature also minimizes saving time, especially when storing measurements via a slow network drive;
  • The base station simulator has been made more robust, especially when connecting multiple instances in the same DASY8/6 Module SAR software session. The PowerSource1 now supports all system performance check frequencies in the 600 – 6000 MHz range;
  • The report generator tool has been further extended. It is now possible to report both user-specified and actually used grid settings;
  • The API interface has also been extended to support system performance checks and validations. A new command for exporting the measured and post-processed fields has also been added;
  • The DASY8/6 software update process has been simplified in that the Preferences and Mother Scan data are automatically copied over for Module SAR V16.2 users.

As always, you can download the latest software versions, application notes and system handbooks from our website.
