The Fundamentals Of Signal Generation

Erik Diez (Keysight/Agilent Technologies) wrote a great article in Electronic Design describing the fundamentals of signal generators - indispensable tools for developing and testing electronic devices and systems.

Being from Keysight, of course they lay claim to the beginnings of the electronic test-and-measurement industry: the model 200A audio oscillator for the Walt Disney Company—in 1940, used for the movie “Fantasia.”
Today, typical applications include RF/IF signal generation and LO substitution, as well as radar, GPS, and avionics signal simulation.  In modern wireless communications systems, signal generators supporting a range of digital-modulation formats are commonly used to test digital receivers and transmitters against increasingly complex requirements.
