Now I see that some of you A-holes are hacking your SDS2354X from a cheap ass SDS2104X.
When you buying cheap version to hack it. There is a big chance, that you will get worse result than original unhacked version.
Just because any factory has quality control check. And when some device doesn't pass quality check due to a slightly out of spec parameters they can sell it as lower grade version.
So, hacked SDS2104X is not equals to original SDS2354X from a factory. The difference is hidden in hardware frontend (ADC, amplifiers, etc). At a glance it looks exactly the same, because it running the same software. But they are not. Because low grade model may use worse components quality (factory rejected)
It may use exactly the same chip as a top-level device model, but it was rejected on the factory due to a little worse parameters. Both chips may be from the same package, with the same part number. Both can meet chip specification. But cheap model will have a little worse parameters.
