I've learned that expecting companies to eventually fix bugs or add features is a mistake. If the product you're buying doesn't do what you need it to do right from the start, it's better to look elsewhere.
Hello! I am very bad understand English and use Google Translate. Google translated so that I nothing do not understand :-). Please explain what you mean by writing this message?
The fact that I paid for the SDS2202 and i hope that soon he will come to me ...
You claim that the firmware update will not? And Siglent will not fix bugs?
Siglent will of course fix some bugs. It may be soon, or it may be late. Some bugs you may be waiting a long time for fixes, and a few may
never get fixed, if they're not deemed important enough to affect sales. Or a new model comes out that supercedes your model.
So Marmad meant what he said: if you will be unhappy that some bug that may be important to you may never get fixed, don't pay your money ahead of time. The only thing you're guaranteed to get is whatever happens to be implemented in the unit when you get it. Anything beyond that is nice, but may never happen.
Ask Siglent (or, Rigol, etc. for that matter), if they will sign an official document guaranteeing that bugs important to you will be fixed. Or that important features or usability fixes that are critical to you will eventually be implemented. They won't do it. Ask them if they will sell it to you for a part of the cost... with the rest to be paid after they eventually get all their claimed features working. They won't do that either.
Marmad was warning folks not to buy based on what they
hope it will some day do... but instead only on
what it does now (bugs and all). Otherwise you may wind up learning the hard way (as some of us old-timers already have).
None of the products are perfect, and all have at least some minor issues that owners have to get used to. That's a fact of life. But not all have the SAME bugs and limitations. If the bugs/limitations of a specific unit are things you CAN accept, and use the instrument in spite of, then you won't have a major problem. But if not, you could be very unhappy indeed, when something you were so sure would get fixed, never does. After you had patiently waited for it for a year or more.
