Probably you found yourself in the situation when you couldn’t get a clear view of a more complex signal on your scope. For instance, it is pretty hard to synchronize packet data waveform. All you get is a mess on your scope screen. With an analog scope it is almost impossible to get it while on Digital Storage Oscilloscope (DSO) you can store trace in memory and then analyze it. But this isn’t very handy. So there is a nice feature on most scopes which is called Trigger Holdoff. Check out this video tutorial from eevblog where Dave shares his thoughts about how this feature can be used in real life situations.
