This session presents a new method for accurate jitter measurements that does not rely on modelling or extrapolation techniques. The method uses hardware-accelerated acquisition on a digital oscilloscope to acquire statistically significant measurement ensembles similar to a bit error rate test set (BERT) with the benefit that one does not need complex modelling software to estimate the total jitter. The method provides accurate measurements in real-world conditions including EMI, power rail noise and with long non-repeating data patterns.

Takeaway

Accurate jitter measurements in real world environments are possible using hardware accelerated acquisition processing on a digital oscilloscope. The benefits include the ability to account for EMI, crosstalk, power rail noise and mechanical vibration in the measurement.

Intended Audience

A working knowledge of oscilloscopes and jitter measurements as well as some background in statistics.
