Frequently Asked Question
I sure can't measure jitter with femtosecond resolution on my scope! How do you do it? How much confidence do you have in the jitter figures that you are quoting for these parts?
Well, we don't have an oscilloscope with (usable) femtosecond time resolution either. Femtosecond level jitter has to be inferred from other measurable values. In our case, there are two types of measurements which allow us to determine jitter at the femtosecond level:
