IMHO the best place to start is the user manual of an oscilloscope (or any piece of test equipment) and the application notes / instruction videos to get a good grasp of what an instrument is capable of. |

But there are things that are not so obvious that I have the biggest fear about. For example, where I connect the ground makes a lot of difference, while in general it doesn't matter or can be ignored. Another one is that digital scopes automatically limit bandwidth after going to some low mV per division of vertical resolution. Noted that while reading discussion thread on RTB2000 here... This should be in the scope manual or application notes, right? |

I´ve been looking for years for it, it doesn´t exist. Although all manuals are written in such a way that one obviously assumes that the user knows how a DSO works. Examining white papers and knowing about digital signal processing seems to be the key. And white papers you can get from all big brands, but also from siglent. --- End quote --- It's time I write one... :-DD --- End quote --- It would be obsolete by the time you finished the first page. |

Although there are not many oscilloscopes out there that automatically limit the bandwidth. Typically a lot of details that are basically specifications can only be found in the manual. The datasheet is more like a cursory spec. sheet. |
