Analysing jitter using a spectrum approach

Keywords:jitter  bit error ratio  test and measurement  spectrum analyser 

This application note includes an explanation of jitter and its components; jitter component separation using a spectrum approach; and bit error ratio estimation.

Tektronix' DPOJET application software uses real time jitter analysis tools with Rj/Dj separation to predict system bit error ratio.

As clock rates increase and timing budgets get smaller, timing characterisation continues to become more important. With today's designs, you can't stop at characterising jitter; you must also be able to investigate the causes of jitter by accurately measuring jitter and use it as a tool to predict system behaviour over periods and with equipment that minimises the total cost to your company. That means being able to analyse jitter using a spectrum approach on a multi-use tool like an oscilloscope. This results in designs being brought to market faster and made more robust to operate better in today's high-speed environment while minimising the investment required for engineering tools.
