An automatic synchronous capture scheme is designed for a fast and large-range frequency hopping receiver based on integrated signal processing and digitization of microwave photons. The designed synchronization scheme is based on direct power detection and serial search strategy. A field-programmable gate array is used in the experiments to control and adjust the timing of locally received frequency-hopping patterns. The automatic synchronous capture receiving for frequency hopping signals with a switching time of ~4 ms and a hopping frequency up to 33 GHz is realized in the experiments.
