I just want to comment that you seem to expect that Siglent should provide service that is nonexistent with ANY other manufacturer out there...
I just looked back over all of my posts. I couldn't see any where I'd said I expect Siglent to provide such a service? I certainly would have been impressed if they did.
Have a look at this video. It's by a guy, who blew the input of an SSA, exactly the same way that I did, doing the exact same thing. Skip to the 1:30 mark.
He apparently has been offered a free repair. If this is true, I certainly would like to know what qualifies him for that, but not myself? I was not asking for a free repair, just a bit less than a €3200 bill to sort out such a minor mishap.
Although he is Chinese, him and his business are based in the UK, just as myself. We ought to be talking to the customer same customer service team too. Why such different treatment? As I said I am assuming that assertion is true.
Thank you for clarification, I missed that.
I guess there is a difference between entry level inexpensive instrument and one that cost 5 times as much.
Also, we don't really know how that person reported problem to point of sale. Maybe it was accepted as a warranty claim, not as user damaged equipment...
In your place, I would not expect Siglent to repair for free. If they did, I would be happy, but certainly they wouldn't owe it to me to do so.
Also, don't take for granted what people with Youtube channels say, or think that the way how manufacturers treat them is same as everybody else. They sometimes not only get offered free repairs, but all kinds of free equipment in the first place in exchange for reviews or simply web presence...
But all that is a moot point now. Most important thing is that you, with your competence and knowledge, were able to repair expensive instrument. That was nice work.
I would, if I may, would like to invite everybody to a discussion as to how they protect their SA inputs from damage in various potentially dangerous situations. That would be one very useful topic for us all.
