The Bluetooth® wireless standard has been an unparalleled success. It has found its way into virtually all smartphones, PCs, cars, entertainment hardware and wearables. Bluetooth SIG reports that more than 8 billion devices are currently in use. Bluetooth supports Internet of Things (IoT) technologies and direction finding methods, making it a sure bet for the future as well.This white paper summarizes the various Bluetooth technologies with a focus on the physical layer in line with core specification version 5.1.

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.

5G networks will need to offer more capacity and flexibility while lowering the operational expenses of the system. Two new technologies can simultaneously address both the increase in capacity and the increase in energy efficiency: Virtualization & Massive MIMO. This white paper provides an overview of test solutions addressing current and future requirements for antenna verification including both conducted and over-the-air (OTA) test methods, which result from applying Massive MIMO antenna technology.This white papers complements the white paper (1MA276) from Rohde & Schwarz, which introduces fundamental theory behind beamforming antennas and provides calculation methods for radiation patterns, a number of simulation results as well as some real world measurement results for small linear arrays.

RF pulse measurements, to characterize the signal in the frequency domain, are traditionally carried out on an RF spectrum analyzer. For time related pulse parameters, oscilloscopes are widely used. However, the measurement capabilities of state of the art test and measurement equipment has evolved over time and crosses domains. With a combination of R&S®RTO digital oscilloscope and dedicated pulse analysis software R&S®VSE-K6, pulse signals can be analyzed in both domains, frequency and time.The R&S®RTO digital oscilloscopes are unique in that they allow output of I/Q data for processing. This application note focusses on signal measurement using this instrument.Analysis of an L-/S-band ATC RADAR utilizing the R&S®RTO2044 oscilloscope running Vector Signal Explorer Software R&S®VSE and Pulse Analysis personality R&S®VSE-K6 is followed by measurements on an X-band RADAR utilizing R&S®FSW, R&S®FPS, R&S®FSV or FSVA signal & spectrum analyzers with the same dedicated R&S®VSE-K6 software.
