Jitter Measurements on Long Patterns with 86100DU-401 Software
应用文章
Today’s devices are characterized using a variety of test patterns. A commonly used test sequence for jitter and eye analysis is the Psuedo-Random Binary Sequence (PRBS) having 2^31-1 bits in length. Why test using PRBS-31? PRBS patterns are easy and inexpensive for devices to generate using hardware, and a long pattern like PRBS-31 (2^31-1 bits, or 2,147,483,647 bits) includes bit sequences that effectively stress baseline wander and clock wander in devices.
