Slope Glitch
Source Siglent STB3, 10x probe
Description: On the negative edge of a 156 kHz square wave, a step having a 200ns width adds to the overall fall time of the edge.
It can sometimes be seen as an irregular part of the falling edge of a square wave but can't be captured with a screenshot.

Some Persistence and Colour added shows it's certainly there.

So let's try and find it with Search.....also possible with Trigger settings but then we wouldn't know if was irregular or not.
Search Menu and let's use a Pulse search

And set the period for less than the positive pulse width

Still no hits

Copy settings to Trigger, now we have five events and one directly under the Horizontal position indicator

STOP and timebase increased.
