A phase coherent signal generator apparatus is disclosed that outputs a coherent continuous phase signal that includes fast switched multiple different frequency bursts. The apparatus comprises: a clock generator including an input to receive a reference clock signal, and outputs to independently supply a master clock signal and a slave clock signal; an accumulating digital synthesizer that includes independent inputs to receive the slave clock signal, a digital frequency tune word signal, a phase tune word signal, and a reset signal, and an output that supplies a digital coherent continuous phase signal; a master digital synthesizer that includes independent inputs to receive the master clock signal and the digital frequency tune word signal, and independent outputs to supply the digital phase tune word signal and the reset signal; and a converter that receives the digital coherent continuous phase signal and supplies the coherent continuous phase signal.

Phase disciplined, direct digital synthesizer based, coherent signal generator

A phase coherent signal generator apparatus is disclosed that has fast frequency shifting and numerous phase memory points, outputting a coherent continuous phase signal that includes fast switched multiple different frequency bursts. The apparatus comprises: a clock generator including an input that receives a reference clock signal, an output that supplies a master clock signal, and an output that supplies a slave clock signal; an accumulating digital synthesizer that includes a first input that receives the slave clock signal, a second input that receives a digital frequency tune word signal, a third input that receives a phase tune word signal, a fourth input that receives a reset signal, and an output that supplies a digital coherent continuous phase signal; a master digital synthesizer that includes a first input that receives the master clock signal, a second input that receives the digital frequency tune word signal, a first output that supplies the digital phase tune word signal, and a second output that supplies a reset signal; and a converter that receives the digital coherent continuous phase signal and supplies the coherent continuous phase signal.
