HFAN-04.5.1: Measuring Random Jitter on a Digital Sampling Oscilloscope
Sep 02, 2002
Abstract: Random jitter is playing an increasingly important role in today's high-speed digital communications systems. For example, SONET specifies that an optical transceiver has no more than 10mUIRMS of random jitter (1 UI = 1 Unit Interval = 1 bit period). This would mean for a 10Gbps system, the random jitter must be less than or equal to 1psRMS. This application note describes an improved technique for measuring sub-picosecond random jitter.
