Abstract:

With the continuous development of high-speed serial bus technology application, jitter control method become the key factor of high speed digital system design.In this paper, through to the importance of the jitter test, to study the classification and reason of the dither signal, based on broadband digital oscilloscope, pulse type generator and arbitrary waveform generator building jitter test system. The article on the system structure, principle and using method are introduced in detail, and through the test cases are analyzed in application. Through practice shows that the system can provide high-speed serial circuit design and debugging work with good supporting role.
