at the laboratory LPL
For some years for cold atoms teams of Laser Physics Laboratory (LPL), we use the DDS (direct digital synthesis) to develop RF generators of a few MHz to several hundred MHz essential to the operation experiences.
This technology through specific components, enables us to produce electronic cards suitable for laboratory experiments. They are fully controllable digitally (frequency, amplitude, phase …). This component allows us to generate RF signals of high spectral purity, high stability and low phase noise.
