12720A Gigatronics RF Generator

20GHz Synthesized Microwave Signal/Sweep Generator

The 12720A is a 20 GHz RF Generator from Gigatronics. An rf generator is a tool engineers use to generate sinusoidal outputs while testing electronic equipment. The output will automatically have its frequency varied or swept between frequencies. A “sweep” is one complete cycle of a frequency variation. Engineers use rf signal generators as test equipment, mostly to measure responses of filters, amplifiers, and electrical components.
