DASY6 and cSAR3D: Detailed Guidance for 5G NR FR1

To unify 5G testing, two new Application Notes provide detailed user guidance for testing any 5G NR FR1 transmitter with DASY6 and cSAR3D. And we have more good news as SPEAG has received ISO/IEC 17025 accreditation to calibrate dosimetric probes up to 10 GHz and BNNSPEAG for field probes between 100 kHz – 6 GHz.

SPEAG is pleased to announce the release of two new Application Notes that provide detailed guidance for DASY6 and cSAR3D testing of wireless devices using 5G New Radio Frequency Range 1 (5G NR FR1). Both Application Notes – “cDASY6 SAR Measurements: 5G NR FR1 SAR Evaluations”, and “5G NR FR1 Evaluations with cSAR3D” – are available for immediate download.

These Application Notes are in line with our Z43 contributions to the draft of the Technical Report that is currently in preparation by the IEC Technical Committee 106 Joint Working Group 13. They also include many valuable inputs from regulators. The guidelines are also consistent with the procedures applied by many test houses to achieve device approvals from the U.S. Federal Communications Commission (FCC). These include carrier aggregation for simultaneous transmission in multiple bands, the use of sub-carrier spacing to support wider bandwidths, dual connectivity between 4G and 5G, and power reduction. Updated uncertainty budgets have also been added.

Extended Calibration Accreditation

At the end of June, the scope of SPEAG’s ISO/IEC 17025 accreditation was extended including dosimetric calibrations of DASY and cSAR3D systems to 10 GHz including the validation sources. This places SPEAG ahead of the IEC/IEEE draft 62209-1528 standard (frequency range: 4 MHz – 10 GHz) to be published in October. The 6 – 10 GHz frequency range has recently been opened for 5G and Wi-Fi transmission technologies. Our calibration capabilities therefore allow the industry to perform accreditation tests today for future wireless devices.

Our sales and testing partner in India, BNNSPEAG, who is accredited for specific absorption rate testing, has recently received ISO 17025 calibration accreditation for EMC probes for the frequency range 100 kHz – 6 GHz, and for E-fields up to 100 V/m (up to 140 V/m in the 100 – 200 MHz range). The EMC field probe calibration facility will serve the entire south east Asia region. They already have the capability of power density testing of wireless devices, including 5G systems.

SPEAG’s extended capabilities and new application notes provide wireless device manufacturers, testing labs and regulatory agencies with the tools needed for 5G device accreditation.
