The need to properly represent the ever changing complexities of the RF environment across communications, surveillance, electronic support measures (ESM) and signal intelligence system (SIGINT) with the advances of signal complexity and bandwidth, requires an enormous test and measurement effort.Extensive field tests are often applied to verify the performance and capabilities under preferably natural but controlled conditions. This is both costly and requires a great deal of time.RF signal environment generation using Test & Measurement equipment brings field tests into the laboratory, where a controlled, cost-effective and reproducible environment exists. The R&S®Pulse Sequencer software is a versatile tool to generate arbitrary and realistic RF signal scenarios ensuringsystem readiness for the real operational world.This application note introduces the R&S®Pulse Sequencer software, explains several examples that are applicable for research, development, before operational and during life-time test in detail, and guides you through the necessary steps, to generate a self-defined, arbitrary real life RF signal environment.

In addition to the main function, power electronic circuits very often have to provide other essential functions such as interfacing with submodules to fulfill system design requirements. Power designs therefore include bus communications in combination with a microcontroller. This can easily lead to more complex designs that may have a negative impact on the conducted emission measurements. Sometimes these auxiliary functions generate emissions infrequently, making it challenging to locate and isolate the root cause. An instrument with a very fast FFT analysis capability is essential to find infrequent events efficiently.

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.
