[sdiy] Oscilloscope Bandwidth

[Oscar Salas]

Thanks all for your replies, I will see that video now, tom.

Magnus, I'm buying a new oscilloscope because the screen of the one that I
have now is failing. It is not that I want more bandwidth.

I have got a good offer with one of 30Mhz. However I'm just wondering if
it is worth to spend more money to other possibilities like 60Mhz (100Mhz
is a little expensive) if I would really need it in the previous described
context. (design, build and trouble-shooting analogue synthesizer modules
and switching power supplies).
