For many experiments and applications of circuit QED systems the time evolution of the quantum system plays an important role. Therefore, studies of the quantum dynamics in the time domain are essential. Here, we present a time domain excitation and readout scheme, which allows us to investigate the quantum behavior of coupled qubit-resonator systems. We apply this scheme to perform Rabi and echo measurements to fully characterize our systems. Additionally, we investigate the decoherence properties at various operation points definded by the applied magnetic flux. Our readout scheme is promising for future simulation experiments of relativistic quantum systems.
