The latest synthesis techniques combined with advanced modulators result in the availability of signal generators that are accurate, flexible, and easy to use.rnSignal generators have evolved rapidly in recent years, in response to the dramatic changes in communications systems during the 1990s. As a result, modern signal generators must often incorporate a wide range of analog and digital modulation capabilities in addition to functions such as frequency sweeps and power sweeps. And phase noise, spurious noise, and harmonics must be almost negligible to perform accurate measurements of phase-modulated systems and their components.
