Plus:
50 Ohm inputs
Autosense inputs
Int. awg
Bodeplot
More decoder protocols
Better DC accuracy
Etc., etc.
As for 2N3055, this does not sound to me everything else, The core parameters are the same. Just not overestimate it. I am waiting for this scope but with this new look and upgrades this seem to me that Siglent will try to push it to a more pricey zone ...
You asked and got your answer. It is superior in it's capabilities, having many functions that were until few years ago only in mid range scopes, some that even DHO4000 does not have (at least at the moment). As I said, if you don't need that, than you should go with simpler and cheaper scope if that one is satisfying your requirements.
I'm sure many people don't need advanced functions and will be more than happy with a simpler scope that still have decent analog performance. And is very affordable. Fantastic news for them.
Fact that advanced functions are not of use to you doesn't make simple cheaper scope equal in capabilities to one that has more capabilities.
It simply means you shouldn't get something that you will not use in full. It would be waste of money..
What the actual price of SDS1000X HD in EU market will be, I have no clue and will not speculate. Even if somebody knows, they won't say anything before Siglent authorizes release of scope and publication of the price in which case it will be published for everyone to know anyways. Same as any other manufacturer.
