New Line of Synthesizers
GED completed development of a family of both phase-locked and direct digital synthesizers. Phase-locked synthesizers feature low noise signals
up to 8 GHz. Direct digital synthesizers (DDS) feature high resolution (less than 1 Hz step size). Both families can be customized to meet your specific requirements.
