PIM (passive intermodulation) occurs at very high power levels and is common in duplex filters, cables, and connectors. This application note discusses fast and accurate ways to measure and detect passive intermodulation.
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.
This application note provides information on the testing of a Buck-type DC/DC subsystem that uses switch mode power supply technology and the oscilloscopes used to conduct the test.
This application note describes how all required receiver (Rx) tests (TS36.141 Chapter 7) can be performed quickly and easily by using vector signal generators from Rohde & Schwarz.
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.
