SPEAG combines CMX500 OBT with the DASY8-3D system for automated SAR testing of 5G NR devices SPEAG and Rohde & Schwarz expand their long-term collaboration with the combination of the CMX500 wideband radio communication tester with the DASY8-3D utilising the enhanced DASY8 Application Programming Interface. This combination allows manufacturers of wireless devices to perform Specific Absorption Rate tests of 5G FR1 devices using the future-proof CMX500 multi-technology, multi-channel one-box signaling tester.

SPEAG, a global leader of dosimetric test systems, has combined the CMX500 OBT from Rohde & Schwarz with its advanced specific absorption rate (SAR) measurement system, DASY83D. The CMX500 OBT emulates a 5G new radio (NR) FR1 base station, fulfilling the requirements for SAR testing of 5G NR devices and providing ease of use for the test engineer. The CMX500 radio communication tester supports cellular technologies such as LTE, 5G NR, as well as non-cellular technologies like Wi-Fi, all in a single instrument. The latest test feature sets, including state-of-the-art wireless technologies like NR-NTN, 5G RedCap, and Wi-Fi 7, provides a long-term, future-proof callbox platform.
The evolution of wireless technology has enabled the creation of an increasing number of wireless products that function close to the human body. These products range from cell phones and smart watches to AR/XR goggles, all of which need to ensure their SAR values meet the essential regulatory requirements imposed by many countries. For instance, the Federal Communications Commission (FCC) in the USA, Innovation, Science and Economic Development (ISED) in Canada, and the European Union have all established stringent SAR regulations and continuously developed safety standards for decades. Several other countries, including China, Vietnam, and India, have gradually adopted similar market access regulation requirements regarding the SAR of radio equipment in recent years. Globally, numerous regulatory test labs and market surveillance test labs are equipped with SPEAG systems for SAR testing.
The successful collaboration between SPEAG and Rohde & Schwarz is testimony to the long-term strategy of both companies for leadership and innovation in test and measurement applications for the wireless industry.
