Certainly there are some maturity differences and one in particular is addressed with a recent firmware addition that provides for EasyScopeX support in X-U models. I am not aware of any other issues.
All our new stock has to be updated with this version before sale.

I don't believe Siglent have made changes to any component quality.


--- Quote ---Finally, if I am going to play with signals having frequency over 100 MHz (for instance to measure attenuation of a RF filter at 130 MHz), would a scope bandwidth of 100 MHz be fine if I just measure the scope's attenuation beforehand and take it into account? Am I correct?

You could and results would be indicative of performance but amplitude would of course not be correct.

SDS1202X-E could be the better choice for you at this price point.
Bathyscaphe:
Thanks for your help, I decided to purchase a SDS1202X-E. If I ever needed a four channel scope some day for decoding multiple digital transmissions, I could buy a logic analyser. Otherwise I have no need for 4 channels. I would be even happy to just see whether the transmission is OK or not.
tzok:
After some time, it is worth to mention, that SDS1104X-U is still the only X-U series model, and for all that time it received 1 firmware update, while SDS1104X-E had 4 FW updates and 2 OS updates since last (and only) FW update of X-U :(
