Rohde & Schwarz and Ceva Announce Over-the-Air Bluetooth Test Solution

The next Bluetooth release is expected to be ratified soon. One important new feature is the Unified Test Protocol (UTP) Test Mode for Bluetooth Low Energy, that will complement existing test methods. The UTP Test Mode will additionally enable over-the-air (OTA) controlled device testing, which will simplify measurements of small and highly integrated devices enormously, since no direct wired connection to the tester is needed. Rohde & Schwarz and Ceva, in close cooperation, have developed a solution for this new test mode.

Fresh From the Bench: QuantAsylum QA403 32-bit Audio Analyzer

The QuantAsylum QA403, the 4th generation audio analyzer from the company founded by Matt Taylor in 2012, has a lot to offer. In particular when a user gets tips and guidance from someone like Bob Cordell, no less. The QuantAsylum QA403 Analyzer was the result of a complete redesign imposed by the silicon shortages and supply chain disruptions, pre- and post-pandemic. It appears that the efforts made were well worth it. Jan Didden shares his impressions.
