Dosimetric test systems developer SPEAG 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, provide 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 U.S. Federal Communications Commission, 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.
