A signal generator is one of a class of electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typically used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well.
A comb generator is a signal generator that produces multiple harmonics of its input signal. The appearance of the output at the spectrum analyzer screen, resembling teeth of a comb, gave the device its name. Comb generators find wide range of uses in microwave technology. E.g., synchronous signals in wide frequency bandwidth can be produced by ...

A small fraction of the signal in the microwave cavity is coupled into a coaxial cable and then sent to a coherent radio receiver. The microwave signal coming out of the maser is very weak, a few picowatts. The frequency of the signal is fixed and extremely stable. The coherent receiver is used to amplify the signal and change the frequency.
BNC Scientific operates as a manufacturer's representative for technologies in microwave signal generation, lock-in amplifiers, spectrum analyzers, and high-frequency arbitrary waveform generators. In 2012, BNC began the development of its line of RF/Microwave Signal Generators, Signal Analyzers, and Spectrum Analysis tools to address industry ...
The core of microwave analog signal processing is the dispersive delay structure (DDS), which differentiates frequency components of an input signal based on the group delay frequency response of the DDS. In this structure, a linear up-chirp DDS delays higher-frequency components, while a down-chirp DDS delays lower-frequency components.
