A Quasi-Coherent Sampling Method for Wideband Data Acquistion

摘要

This paper proposes a quasi-coherent equivalent- time sampling method to acquire repetitive wideband waveform sig- nals with high throughput. We have already proposed a new sampling system which incorporates the pre-trigger ability and the time jitter reduction function for a fluctuated input signal while maintaining the waveform recording efficiency. The quasi-coherent sampling method proposed in this paper can be adopted to it in order to improve its data acquisition throughput significantly. Numerical simulation results show effectiveness of our proposed method.
