This guide from Keysight introduces the fundamentals of RF signal generators, covering how they produce precise, stable signals for testing wireless and radar devices. It explains types of signal generators (analog, vector, agile), key specs (power, accuracy, speed), and use cases from component testing to electronic warfare. Detailed sections describe amplitude, frequency control, spectral purity, and fast switching. It emphasizes how advanced signal generators improve test accuracy and efficiency, critical for modern, multi-band devices that demand faster throughput and more reliable measurements.
