This application note, Part 4 of the Fundamentals of RF and Microwave Power Measurements, overviews various instrumentation for measuring RF and microwave power, including spectrum analyzers, microwave receivers, network analyzers, and the most accurate method, power sensors/meters. It begins with the unknown signal, of arbitrary modulation format, and draws applicationoriented comparisons for selection of the best instrumentation technology and products.
