A Method for capturing abnormal signals with an oscilloscope

Welcome!

Note: 1. the oscilloscope must be a digital 2. The oscilloscope must have a afterglow function 3. The oscilloscope must have a trigger function (it seems that the digital oscilloscope has this function)

 

Step 1: Enable the oscilloscope afterglow function (permanently enabled)

 

Step 2: Access to generate a signal source header to the oscilloscope (a bit nonsense)

 

Step 3: Observe abnormal signal characteristics of the signal source through the signal source afterglow to determine the trigger mode,

For example, if the pulse signal suddenly rises when the abnormal signal is greater than the normal signal used, it can be set to Level Trigger.

If the slope of the abnormal signal is different from that of the normal signal, you can set it to slope trigger.

And so on.

 

Step 4: After determining the trigger mode in step 3, set the oscilloscope trigger mode and set the trigger mode to a single trigger. That is, if an abnormal signal exists, the oscilloscope can capture the signal and display it.
