- The solution combining Rohde & Schwarz’s CMX500 broadband radio communication tester with Speag’s DASY8-3D system enables manufacturers of wireless communication devices to automatically perform specific absorption rate (SAR) tests of 5G devices operating in the FR1 frequency band.
Many wireless communication devices operate close to the human body. Whether cell phones, smartwatches or even glasses for augmented reality applications, all these products must comply with SAR 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. 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.
Speag, a provider of dosimetric test systems, has combined the CMX500 OBT tester from Rohde & Schwarz with its 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 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 include wireless technologies like NR-NTN, 5G RedCap, and Wi-Fi 7.
