Measure Clock Edge Timing Using Oscilloscopes

Analyzing clock jitter requires capturing repeated clock edges with enough timing resolution to compare variation from cycle to cycle. The test setup needs an oscilloscope, stable clock acquisition, and jitter analysis that can measure edge timing variation, cycle-to-cycle jitter, and time interval error (TIE) across a large sample of clock events.

To perform the test, engineers acquire the clock waveform, apply jitter measurements to the captured edge data, and review the results using statistical analysis of repeated timing events. Separating random and deterministic jitter components makes it possible to correlate measured timing variation with behaviors such as power supply noise, crosstalk, or phase-locked loop instability.

Clock Jitter Analysis Solution

Accurate clock jitter analysis requires an oscilloscope that can acquire stable clock waveforms over many cycles and software that can automate timing measurements across the captured record. Keysight Advanced benchtop oscilloscopes capture the clock waveform, while jitter analysis oscilloscope software measures cycle-to-cycle jitter, TIE, and related edge timing behavior. Passive probes connect the clock signal to the oscilloscope with the high signal fidelity needed for precise timing analysis. Together, the oscilloscope, software, and probe provide a complete setup for statistical jitter evaluation and root-cause isolation in high-speed clock signals.
