The Research of a Random Sampling Method with Automatic Calibration Capability of DSO

摘要

The random sampling method is offien used to enhance sampling rate of DSO(Digital Story Oscilloscope) and to improve the bandwidth of testable periodical signal. This paper discusses the realization methods of random sampling and proposed a new random sampling method with automatic calibration capability. With this method, the acquisition and calibration can be finished in synchronal, the errors of sampling site measurement will be reduced.
