This thesis deals with the design and construction of a versatile digital frequency synthesizer for implementation in the state-dependent transport of Cesium atoms. The versatile digital frequency synthesizer consists of a field programmable gate array interfaced with a low noise direct digital synthesizer that will be used for amplitude, phase and frequency modulation. The versatile digital frequency synthesizer provides better flexibility, for generating arbitrary waveforms, and lower phase noise than the previous setup. The measured reduction in phase noise of around 20dB corresponds to an increase in the lifetime of atoms by two orders of magnitude. This improved phase noise specification with the ability to generate arbitrary waveforms opens up possibilities for transporting atoms over macroscopic distances and eventually realizing an atom interferometer with a large space-time area.
