Abstract
A signal synthesizer includes a high frequency offset stage having a high frequency offset source and frequency translation element in the feedback path of a dual-oscillator offset loop synthesizer. The signal synthesizer achieves low phase noise via noise cancellation when used to provide the first local oscillator of a spectrum analyzer and when the second local oscillator of the spectrum analyzer provides the high frequency offset source to the signal synthesizer.
