Analysis on temporal evolution of the mean frequency is a useful tool for studying bandwidth-limited pulses. Based on a dielectric-loaded power extractor experiment, we present the temporal evolution of the mean frequency of a microwave pulse measured with a field probe. Time- gating study on the detected voltage signal revealed a nominal carrier frequency of 7.8GHz with occasional dips. Further development of the signal analysis scheme is currently underway to facilitate more elaborate pulse parameters identification and pulse stabilization. Key words: frequency evolution, time gating, time window, bandwidth-limited pulse, power extraction.
