This application note explains how to synchronize the signals from multiple R&S®SMBV100A vector signal generators in time.The synchronization of the instruments is based on a master-slave principle where one R&S®SMBV100A acts as master and supplies all necessary synchronization signals to the other instruments (slaves). The setup is simple and provides highly synchronized test signals. Time synchronous signals are needed in several applications. The master-slave setup is ideal for basic MIMO tests, certain GNSS test scenarios and WLAN IEEE 802.11ac non-contiguous channel generation. Furthermore, synchronous baseband signals are the basis for generating phase coherent RF signals with the R&S®SMBV100A.

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.
