In order to generate noise power ratio stimulus signals and to measure the resulting noise power ratio of a device under test (DUT), Rohde & Schwarz offers the Noise Power Ratio (NPR) as an add-on tool for WinIQSIM / WinIQSIM2™ software. This NPR measurement technique drastically reduces measurement time compared to classic gain wobbling, and is able to characterize the linearity of a wideband amplifier over a custom frequency range. This application note provides an overview of the software, its features, hardware and software requirements, installation, parameters, and more.
This application note provides an overview of the MHL technology and also describes the Rohde & Schwarz compliance test solution for the system part of the current MHL2.0 standard version.
At the beginning of 2015, around 1200 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. In order ensure proper performance in the satellite transponders in the payload, on-orbit measurements must be made as a part of maintenance. This application note focuses on satellite post-launch or on-orbit measurements, and monitoring strategies used for satellite functionality checks when running maintenance routines.
This application note introduces the working principles of a conventional trigger system and explains the advantages of the real-time capable digital trigger of the RTO oscilloscopes.
