I guess that way they don't even have to put a fuse in it. --- End quote --- That's an advantage in some use cases. How many times have we seen somebody stick the probes in a wall socket or worse with them plugged into the current jacks? Really you should be using a clamp probe for line voltage stuff. The Fluke 101 is a low cost meter with the reliability and safety of Fluke. It's not something I'd buy, but that doesn't mean it isn't a good value, it could be perfectly well suited for an electrician. |

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 |

Do it, otherwise I will someday.... ;D |

Or compilation from different sources. I might try to do that as I go further with my learning curve, to note where I read what and what I learnt from practice... I noticed that The Art of Electronics, the third edition, has a chapter on oscilloscopes and a chapter on transmission lines that I study now. And I remember low pass and high pass filters from that book, and differentiation and integration of signal. Another book "An Introduction to Electrical Instrumentation" by Gregory, 1977 has interesting chapter 4.2 - Components impurity effects on signals. Also explains nicely (to me at least) what stands behind probes compensation and that at some unfavorable conditions oscillation might occur with probes connected. Is it really like each time something to be measured some calibration or attenuation to the circuit being measured is needed? Would then playing with embedded generator be useful as to get sense of what is on the scope and then what should be in reality? |

People on this forum with decades of experience and good theoretical knowledge should really join efforts and write down that mythical textbook about oscilloscopes. |
