Data Collected using HP 3048A

Four Frequencies from Jitter Tables

62.5MHz only to 2MHz offset due to Equipment Limitation

Jitter is frequency dependent. Below are typical values at select frequencies.

Phase Jitter

TIE

Per MJSQ spec (Methodologies for Jitter and Signal Quality specifications)

Rj and Dj

, measured on LeCroy LC684 Digital Storage Scope, directly into 50 ohm input, with Amherst M1 software.
