| Abstract: | The process of analysis and evaluation of the measurement uncertainty of crosstalk of digital storage oscilloscope（DSO） is described.Some error sources of crosstalk measurement are discussed,including the signal errors,the gain errors of DSO,the amplitude measuring errors of DSO,the resolution of DSO,the measurement repeatability etc.The uncertainty model of crosstalk of DSO is given.Combined with an example of experiment,the analysis and uncertainty evaluation results of crosstalk is presented. |
