A system to create periodic pulse sequences with defined absolute phase comprises a phase coherent analyzer and a pulse generator. The phase coherent analyzer and the pulse generator are connected with each other. The pulse generator has a clock input connected to the analyzer for receiving a clock signal from the analyzer. The system comprises a trigger line via which a marker signal is provided to at least one of the analyzer and the pulse generator. The marker signal temporally aligns an output signal of the pulse generator with a measurement process of the analyzer. Further, a method of creating periodic pulse sequences with defined absolute phase is described.
