10BASE-T1S Ethernet enables the integration of diverse sensors into an automotive-Ethernet vehicle supply system, for example short-range radar sensors for detecting blind spots or ultrasonic sensors for the parking assistant. For reliable operation of the functions, data transmission over 10BASE‑T1S Ethernet must be assured at all times and in every climatic environment. Functionality must be tested during development and in production. Only 10BASE-T1S Ethernet interfaces that have passed compliance testing in line with IEEE 802.3cg can be deployed in vehicles. Consequently, vehicle manufacturers and their suppliers need measuring equipment that allows them to perform these tests quickly and reliably.

With recent enhancements in semiconductor technology the microwave frequency range beyond 50 GHz becomes more and more attractive especially for wideband communication applications like 802.11ad, microwave links or automotive RADAR. Low phase noise is essential for these applications to work properly. Accurate measurement of phase noise is needed to improve the performance. However, test setups at these frequencies become difficult, especially when cross correlation of two receive paths is needed to suppress additional phase noise added by the local oscillators or mixer stages. Two external harmonic mixers in combination with a commercially available phase noise tester are used for phase noise analysis. Signal sources with frequencies up to 500 GHz can theoretically be measured with this setup.

More and more everyday items such as household appliances, vehicles, lights, etc. are now connected to the Internet, forming what is known as the "Internet of Things". Even clothing with sewn-in sensors to measure vital functions can now connect to the Internet and transmit data to cloud services. These different things use a variety of wireless technology standards to establish a connection. Due to its popularity, one of the most important standards is Bluetooth (or Bluetooth Low Energy). Before a new product with Bluetooth functionality can be launched, the qualification process defined by the Bluetooth SIG must be successfully completed. To save time and money, performance tests need to be performed in the development stage. This application note describes how to use the R&S CMW platform to perform the measurements defined in Bluetooth test specification version 5. As an alternative solution, we also cover how to perform almost all of the measurements with a spectrum analyzer and signal generator.The Bluetooth® word mark and logos are registered trademarks owned by Bluetooth SIG, Inc. and any use of such marks by Rohde & Schwarz is under license.
