SPEAG and Rohde & Schwarz collaborate on automated SAR testing of 5G NR devices

Dosimetric test system manufacturer SPEAG has combined the CMX500 OBT from Rohde & Schwarz with its advanced specific absorption rate (SAR) measurement system, DASY83D for automated SAR testing of 5G NR devices.

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.

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.
