LAB_WM780 - Using Spread Spectrum Clock Tracking

Spread Spectrum clocking is being used almost universally in order to decrease electromagnetic emissions in electronic systems. Being able to measure and characterize the variations in clock frequency is a major concern. LeCroy oscilloscopes offer Spread Spectrum Clock tracking to simplify these measurements

Summary
Spread Spectrum clocking is LeCroy offers spread spectrum clock tracking (SSCTrack) which extracts
being used almost universally and displays the instantaneous frequency variation of the clock as a
