Both resistive type and reactive type power divider/combiners can be used to fan-in or fan-out RF signals. However, both types distribute RF signals in a different fashion. This white paper offers guidelines and considerations for determining a divider/combiner for each application.
Many spectrum analyzers can detect phase noise levels automatically, making phase noise measurements a task without much thought. This paper discusses key aspects in determining phase noise measurements, and presents formulas and examples that may be used for simplifying measurements.
Tactical radios typically use frequency hopping in order to minimize interference and jamming threats. However, when a frequency hopping technique is applied, the radio may interfere with adjacent signal bands or inband communications technologies. This application note explains the benefits of using a Rohde & Schwarz signal and spectrum analyzer (with realtime option) to enable wideband signal analysis and high probability of intercept in the testing of radios in a frequency hopping mode.
This application note explains how to troubleshoot an eNodeB using a spectrum analyzer with LTE over-the-air (OTA) measurements.
At the beginning of 2015, around 1,200 satellites were fully operational in orbit around the planet, half of which were communication satellites. This number of satellites is expected to expand at a progressive rate within the next years. To have success in developing satellite projects, reliable testing needs to be done at each stage. This application note focuses on RF component and module testing of satellite communication payloads using R&S instruments at pre-launch levels.
