Finding the Cause of an Infrequent Glitch Using Oscilloscopes

Application Notes

Infrequent glitches, non-monotonic edges, and metastable signals are a few of the troublesome signal anomalies that can cause engineers long sleepless nights. Typically troubleshooting anomalies goes through a three step process;

  1. Visible identification; confirm anomalies exist
  2. Isolation; separate the anomalies from good signals
  3. Insight collection; find clues leading to the root cause (such as the frequency of the anomalies, unique patterns, or other identifiers to lead to diagnosis of the reason for the anomaly in the first place.)

 

This application note is a supplement to “Finding the coupling signal that causes the glitch”, which is one of the built-in automatic demonstrations in the Keysight Technologies, Inc. InfiniiVision 6000 X-Series. This application note covers the following topics:

  • Fast waveform update rate and why it is important
  • Hardware InfiniiScan Zone touch trigger and how it accelerates your signal isolation
  • Color grade enabled segmented memory and how it gives more insight into your signals
  • 10-digit counter and totalizer and how the trigger qualified event counter aids your troubleshooting
