Really ? My first DSO had 2.5 Kpts memory/channel so to get the best from it you used it wisely. Even the other 2 laterTeks I had were similarly pitiful. What are we actually trying to do here, teach the reader some obscure scope usage method rather than proper well know methods that return universally predictable results from any DSO ? --- End quote --- No, I think you've used other scopes. Your argument seems to be not every scope can do it so people shouldn't do it or talk about it? I'm really confused about people being vehemently against this when it's just another way to use the tool. Plenty of scopes can do things my scopes can't but I'm not telling them they don't know how to use a DSO because they use those available features. Some people don't see the point in doing it and that's fine but it's still another method to do a job regardless your feelings. It's literally capture and zoom out(or scroll to the point of interest) OR capture and zoom in, then zoom back out again(or scroll to the point of interest). One of these is the shortcut. |

If you get more signal then your scope supports recording beyond the screen. --- End quote --- Shouldn´t be the trigger set to "manual" in this case ? |

I forgot to mention the trigger mode should be set to 'normal'. Not single, not automatic. |

A 1khz Signal and then 100ns ? Nevertheless, I´ve just tried it out on the sds2104x+ and the signal disappear. Now it´s your turn, Gandalf_Sr…. |

To clarify, the scope has to be in 'normal' mode or it will retrigger itself after the probe is removed from the calibrator output. Anyway, after the probe was disconnected, I could wind the horizontal axis all the way out to 10 mS/div and still see valid waveform so it looks like the MSO5000 does capture outside the visible screen area. |
