Yeah: it could be said it's a 18-20 MHZ BW device,
How do you define that? How do you come up with it?
Do you own such a device now?
I don't see anything special happening at 20MHz and I have such a device.
Why do you say something like that?
Please note I'm not bashing the device.
Yes, you are!
Just don't buy it if you hate it. Why bother?
@jebem: thank you very much for the information you provide.
@Aldo22: Now you are throwing a temper tantrum. Please grow up and spare us any drama. I have some questions for you:
1) It has been said this device has a 100 MSa/s ADC. If so, I can't understand how it could be good up to 120 MHz bandwidth. I'm sure you can, probably mentioning something fancy like the ancient aliens that gave civilization to us or something like that. Could you demonstrate DSO2512G has a faster than 100 Msa/s ADC instead? If you can, please do so. I would really like to hear that, even if a real 20 MHz bandwidth already seems to me good enough for the price.
2) I define DSO2512G as a 18-20 MHz device because:
a) I do own a DSO154Pro also from Zeeweii, which I think is quite a fine device for the price, It is advertised as a 18 MHz device, one channel, with a €40 price tag. So I think DSO2512G is like a siamese couple of DSO154Pro, perhaps a little more, with a €100 price tag. To me, that seems to add up, I mean, similar bandwidth, etc, but two channels, not one, for double the price.
b) It has been reported DSO2512G has about 36-40 MHz bandwidth. Please note this quote is from you:
So in 2 channel mode not overclocked: 48Mhz -> 4.8Mhz -> 16MHz
2-channel mode overclocked: 60Mhz -> 6Mhz -> 20MHz
And then we have this quote from gitm:
A general comment about the DSO2512G. It's bandwidth is not 100/120 MHz. That's bullshit. It's actual bandwidth is about 35/37 MHz and that's with decent probes, 250 Mhz 1X/10X from Probemaster.
I'm sure you remember how yor reply included a boxing emoji and how you took a couple jabs after that. I can't help but think a 100 Msa/s ADC adds up with about 36-40 MHz bandwidth. I asked if that was with just one channel active so it would be about 18-20 MHz with both channels active. No answer to that, so I can only assume that's the case.
Your assertion that perhaps this device would have been designed to work with only small signals to have higher bandwidth is ludicrous. To me that means that I should use a 100x probe when working with, say, 24 V signals. No way. I'm going to say its a 20 MHz device instead. I say 20 MHz since it's a dual-channel device, and I want to know what it's able to do with both channels active and real-world signals. Those half-truth assertions can remain for marketing people and other thieves of that kind.
3) I'm sure you don't see anything special at 20 MHz but I have noted you don't want to see anything that could mean you gullibly bought it thinking Zeeweii marketing hype is true. You are the only guy here gringing anytime somebody says that advertised bandwidth has to be an outright lie. If you continue that way, I --and probably others-- will have to think your opinion isn't valuable. But, hey, that's not my problem, please feel free to do as you want. Ancient centro-american natives thought that to make his penis bleed would make the gods happy so droughts could be avoided. I'm fine with that too --as long as it's not my penis the one to be wounded-- but know what? Droughts can't be avoided that way. Perhaps the gods are to be blamed for that?
4) No, I'm not bashing this device. I even could buy it knowing its shortcomings, wich aren't that bad for the price. Particularly after knowing other devices in that price range aren't perfect either. Do you need to gringe if I say this is not a 120 MHz device? Well, that's your problem.
5) No, I don't feel any hate for any device. It would be ludicrous to hate an unanimated thing. I do hate marketing thieves, however.
6) Perhaps I'll buy this device, perhaps not. But anyway I'm not going to recommend it as a 120 MHz device. Can you understand that?
Last but not least, I don't really care if you reply to this post or what could that reply say. I already wasted too much time with your "arguments". Particularlly if they are just temper trantrums.
