| Abstract: | This paper discusses the theory and application of Random Sampling in Peak-Power Analyzer. Firstly,it briefly introduces the theory of Random Sampling technique,and specially detail design idea,hardware realization,one Random Sampling process and the calculation of Trigger Position. Also,it introduces the process of organizing more Random Sampling. The Peak-Power Analyzer adopted random Sampling technique has achieved 60dB power dynamic range and 5G/s equivalent sampling rate. The result proves that Random Sampling technique can meet the requirement of the Peak-Power analyze. |
