I agree. However I would like to know what our more experienced fellow forum members would have to say.
If, as said, DSO2512 does sample at 200/100 MSa/s and does sin(x)/x interpolation, that would add up with the results? 100/2.5 = 40 MHz.
However I doubt it's being tested with both channels activated?
I don't quite understand how you come up with these numbers.
I have already shown the different "bandwidths" of this device here before.
By this I mean the limit up to which it can still measure the frequency, not the absence of "artifacts".
2 channel/standard mode: ~48MHz
2 channel/OC mode: ~60MHz
1 channel/standard mode: ~96MHz
1 channel/OC mode: ~120MHz
The 40 MHz you mentioned refer to the square wave. It is the state you see on the DSO154 at 6MHz.
The DSO2512 is specified with 500Ms/s. I guess in reality it is probably like this (Or they lie!
):
2 channel/standard mode: 200Ms/s
2 channel/OC mode:250Ms/s
1 channel/standard mode: 400Ms/s
1 channel/OC mode: 500Ms/s
Would be DSO2512 good enough to do some low-end but serious work or is it just a toy?
Opinions differ on this question.
It's enough for me for the time being.
It's the first and only oscilloscope for me, so I have no comparison
I'd say it's a lot better than
no oscilloscope and a little more usable than the DSO154.
I don't use it professionally, just as a hobby. (Arduino etc.)
I would say if you want to buy a new handheld 2-channel toy-or-not oscilloscope, then there is nothing that costs less than the DSO2512 (I paid 77.50 CHF including delivery)
I don't have a dedicated work desk for these devices, so I need to be able to easily stow them in a drawer. Therefore handheld.
