good morning World
![Azn ^-^](https://www.eevblog.com/forum/Smileys/default/azn.gif)
the choice of the oscilloscope stole my life, I dreamed of probes tonight
![Embarrassed :-[](https://www.eevblog.com/forum/Smileys/default/embarrassed.gif)
-circlotron: true, if the display is bigger it wouldn't be bad (the models taken into consideration have a good display, excluding ds1052 but I don't think I'll take that..)
-james: i quickly looked at oscilloscopes used on ebay.. but they sell them for a little less than the new price

-wizard69: unfortunately I have to buy online and anyway even trying the oscilloscope I wouldn't understand much...
Thanks for instructive link, two things: I already have some books, although for now I have preferred the electrotechnical part...
and I would like to let you know that I am not only interested in audio devices.. I try to repair any failed device: I fixed a mouse last week and repair power supply swich (it was just luck, I usually don't solve problems...

)
thanks for telling me that the oscilloscope helps in troubleshooting.. it helps me believe that it is the right and desired purchase

-alsetalokin: great video, nice music.. I saw that you measured 800vpp, you used 100x probes: need to sell a kidney to buy probes 100x???

-mechatrommer: i inserting woman in the title, just to warn that I wasn't very experienced in electronics. I know few women who use soldering iron and oscilloscope!

-dietert: Are you claiming that these low cost digital oscilloscopes have many problems? to start I will accept the risk ;-)
-magic: thanks for advice, I believe that even if they have limits, they will be fine for my initial use... for memory depth, I think that rigol offers something more than siglent (in the basic models)
-ebclr: thanks for the advice, on the pc I already have NI multisim 14 for play ;-) . But now I would prefer to use a real oscilloscope

-tggzzz: I read now what you write. First I take the oscilloscope, then I will ask for advice on the signal generator. That will be the next purchase

---------------------------------
my reflection just got out of bed:
I am excited to buy a new oscilloscope.. but reading online that using an oscilloscope can be very dangerous..
for example I read:
-it is dangerous to touch the oscilloscope frame... shock hazard
![Cry :'(](https://www.eevblog.com/forum/Smileys/default/cry.gif)
-be careful not to measure devices with mains voltage
-better use an isolation transformer (but it costs too much)
-someone advises to detach the ground of the oscilloscope
![Roll Eyes ::)](https://www.eevblog.com/forum/Smileys/default/rolleyes.gif)
I'm usually cautious, but these warnings scare me
![Embarrassed :-[](https://www.eevblog.com/forum/Smileys/default/embarrassed.gif)
Is it really so dangerous to use an oscilloscope?
Can you reassure me? I begin to have doubts that he is able to use an oscilloscope...

thanks dear friends, you are important for my choice
