I guess the field of hobby electronics is big enough to incorporate someone who really wants to know what their scope can do. This is the most fun thread I have ever been involved with. Truly educational!
Agree..
It's even more than that. By explaining how some measurement on scope is performed, we also spoke about measurement itself. For those playing at home, they might not realise how important this part of electronics is. Many times solving a problem with a circuit is all about devising method how to measure something here and there and by looking at results realize how it works and what is wrong and what is right.
Congratulations on your efforts.
But there are so many subjects to study in electricity and electronics that it may be unconstructive to spend months just studying a small part of all the possibilities of your new oscilloscope.
I am sure that with your intelligence you could have learned to use an oscilloscope like the HAMEG 203 in less than an hour.
Don't you think you've gone in the wrong direction?
Excuse me for this intervention, I am new to this forum, but tried to read the 33 pages of this topic and gave up .....
By that logic, than she shouldn't have bought the scope at all, multimeter is a better choice, because it even simpler, only one knob.... Or maybe not take electronics as a hobby at all, because you can, you know, hurt your head with
thinking..
Point is, some people want learn
more,
not less.. As rstofer nicely said, many years ago, I learned to use analog scope in few hours, including reading the manual cover to cover... Because there is nothing to learn. The notion of X-Y graph with time on abscissa and voltage on ordinate was familiar from elementary school math. Then X-Y mode that you can use to apply any voltage to abscissa and ordinate ... cool, so I can show graphs with two voltages that are correlated to show anything I like.... Triggering was name for a circuit that there to ensure waveform always start sweep at the same part of waveform, so graph on screen would retrace always the same spots on screen so it would be stable, otherwise you would see some scribbles...... Wait, but if signal is not repeating exactly the same all the time, you will see god knows what on screen... That's not cool..
And that is analog scope. You can explain concept of all analog scope can do (and it can't do very much, in fact very little..) on one A4 page. Literally nothing to learn there. And it cannot do more than 10% of even cheapest digital scope of today. Easy to learn, and even less useful..
And with digital scope you don't need many other instruments (most of the time)... I'm not a timenut, so there has been a long time since I used my freq. counter. To verify CPU clock frequency, counter on a scope is more than enough. Also you need special instruments to measure true RMS of a 5 MHz signal. Scope's RMS ( or Stdev function
![Azn ^-^](https://www.eevblog.com/forum/Smileys/default/azn.gif.pagespeed.ce.7t5xC2ZH_H.gif)
) will get you closer to correct value than almost anything else that you have in a lab. etc etc... If there is a instrument that should be called multimeter, that is today's digital scope.
In the old days, you had to learn how to use all of those
individual instruments
one by one. Today, you have them all inside the scope so it takes a bit of a learning curve.
And that is not something that is hard to do. It is
powerful and
enabling and is
worth the effort..
