New toy(?) scope, DSO154pro, 1ch, claimed 40MS/s
<< < (10/19) > >>

My Rigol has two probes. I tried one of them yesterday.
I had no bandwith limitations neither on x1 nor on x10 positions.
I wiil try to do some tests again on everything I find at home :)

14mhz SINE wave at -3db , stable square wave at 500khz

Please someone tell me which oscilloscope can show lossless 3mhz square wave?  thanks
ataradov:
Ideal square wave has infinite spectrum, so no scope can show that. But generally bandwidth 10x the frequency of the square wave shows acceptable results, something that can be called square.

For square waves it is generally better to talk about rise time rather than bandwidth. Those parameters are directly related, but the rise time is easier to visualize and reason about.

Rise time = 0.35 / F_3db. So pick a rise time that you think still looks like a square to you, and you will know the minimum necessary bandwidth  to get that.

And your generator would also have some limited rise time, and you will not be able to observe it better than that. So another way to know what is the best scope for the task is to understand your source.
