When debugging digital designs, it is often difficult-to-impossible to set up an oscilloscope to trigger on specific and unique signal problems. The Keysight Technologies Inc. Zone Trigger, which is available as a standard feature in all InfiniiVision 3000T, 4000 and 6000 X-Series oscilloscopes, can be used in conjunction with conventional oscilloscope triggering to quickly zero-in on problem signals. If you can see the problem signal, then you can trigger on it using Zone Trigger. Learn how to easily use Zone Trigger to capture non-monotonic edges, set-up and hold-time violations, and serial bus arbitrations.
