Find Rare Signal Anomalies Faster

High-speed digital debug often requires finding rare signal anomalies that are buried within otherwise normal waveform activity. These events may appear only occasionally or differ only slightly from the expected pattern, making them difficult to isolate with a conventional stable waveform view. To uncover them, engineers need a measurement approach that can compare repeated waveform behavior and identify outlier events based on parameters such as pulse width, rise time, and fall time.

Isolating these anomalies requires an oscilloscope that can capture repeated waveforms, screen them against learned normal behavior, and automatically mark events that differ from the baseline. In this test setup, the oscilloscope acquires the waveform record, applies anomaly detection to repeated signal activity, and highlights suspect events for review. When implemented properly, this helps engineers focus debug effort on the waveform behavior most likely to explain hidden signal errors in high-speed designs.

High-Speed Digital Debug Solution

Debugging hidden signal errors in high-speed digital designs requires a measurement setup that can screen large waveform populations and automatically highlight the events that break from normal behavior. Keysight Expert benchtop oscilloscopes use built-in anomaly detection to mark outlier waveforms based on measurements such as pulse width, rise time, and fall time across repeated acquisitions. This setup helps engineers review abnormal events in context, compare them against the normal waveform population, and narrow the investigation to the signal conditions most closely associated with intermittent failures.
