The fact that cable TV networks are generally located in densely populated areas or extend over large geographical regions makes the presence of line extenders at regular intervals a necessity. Cascading large numbers of amplifiers however calls for excellent noise, SWR and intermodulation distortion specifications for the integrated amplifiers in order to avoid quality of service dropping below minimum acceptable levels. Composite second order, composite triple beat & cross modulation are commonly used figures to specify the performance of CATV equipment. In this application note we describe how to determine these figures with the aid of R&S SMU200A or AFQ100A and SMV vector signal generators.

Autonomous and semi-autonomous vehicles rely on a complex hardware and software architecture to gather and exploit information from numerous radar sensors. To generate reliable data, the sensors require an unobstructed view of the surroundings. The bumpers or radomes mounted in front of the sensors must not impair radar functionality. This requires extensive testing of the deployed plastic parts and their underlying polymer structure. The R&S®QAR50 is the ideal tool to characterize the material properties of polymers and their influence on the quality of the radar signal at an early design stage and in quality control of material development.

Measurement deviations due to systematic errors of a network analysis system can be drastically reduced by an appropriate system error calibration. After system error correction, the residual measurement uncertainties are - besides the stability, linearity, and dynamic range of the network analyzer system - mainly affected by the quality of the calibration standards and the repeatability of the connections. The effective measurement accuracy of the network analysis system can be determined using the results of successive verification measurements utilizing highly precise verification standards.

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.

The terrestrial television standard DVB T2 is gaining in significance as a result of the growing scarcity of available frequencies. New systems are being tested in many countries around the world. Other countries have already completed the introductory phase for DVB T2. Broadcasting transmitters are subject to particularly stringent standards with respect to broadcast signal quality, because even small faults can lead to service disruptions for many viewers or even disrupt adjacent channels.A single instrument, the R&S®ETL TV analyzer, performs all required DVB-T2 transmitter measurements, from the initial acceptance testing for the transmitter, to measurements performed during commissioning and preventive maintenance.The measurements described here satisfy many country-specific and customer-specific test specifications. Users need only set the limit values accordingly.
