Pulse signal source device

Abstract

The invention discloses a pulse signal source device, and belongs to the field of atomic frequency standards. The device comprises an initial signal source, a control module, a first digital frequency synthesizer, a second digital frequency synthesizer, a phase-looed loop frequency divider, an attenuation matching network, a frequency multiplying and mixing module and a power amplifier. The initial signal source is used for outputting frequency signals; the control module is used for generating reference signals according to the frequency signals, generating keying frequency-modulated signals and generating time sequence control signals by taking the frequency signals as reference; the first digital frequency synthesizer is used for taking the reference signals as reference, performing keying frequency modulation by the keying frequency-modulated signals and generating modulating signals; the second digital frequency synthesizer is used for generating original pulse signals under the control of the time sequence control signals; the phase-locked loop frequency divider is used for processing the original pulse signals by set fractional frequency and outputting pulse signals; the attenuation matching network is used for compensating the pulse signals; the frequency multiplying and mixing module is used for frequency multiplying and mixing of the pulse signals and the modulating signals to acquire optical-detection resonance signals; the power amplifier is used for power amplification of the optical-detection resonance signals.
