A couple of weeks ago I was waiting on a refund, but I had a change of heart when Batronix passed on confident reports from the factory regarding isolation of the problem.
Just received a new SSA3032X Manufactured Jan 2018 and all is well. The spur is looking very much like the earlier instruments at -71dBC, it's fixed.
Noise floor compared to the earlier instruments posted in the thread remains 3 to 4dB inferior. Checked against Siglent data sheet and this machine easily meets minimum spec and meets typical floor all the way up to 3.2 GHz, so no problem with that, very happy.
Winner winner .... you know the rest. Thanks to all who added useful information and technical interest to this thread.
Good!
The main reason was the previous major suspect as I write yesterday here (yesterday edit) :

So, the "guilty" has been found and terminated. Everyone can breathe and sleep again and relax.
Relax ?.....
So anyone with this issue needs to contact Siglent right ?
I meant that the cause of the problem was discovered. It would be a pretty stressful situation if the cause of the problem was not yet found. This, and only this, was the cause of my commentary. And it may not be unclear to anyone that I'm more interested in technology than trading, even if I sometimes do it.
I have also previously said that Siglent made this mistake and Siglent is responsible for it.
I think it is quite unequivocally said.
If I had sold a spectrum analyzer that is part of a potential problem set, I would contact the buyer or buyers and make a request for service. This is no more special than the fact that new cars are called to be repaired several times for many different reasons and constantly.
I do not take a stand on how someone else works. I will only take a position on what and how I do.
Just do not buy from sellers who do not have real after sales customer care.
Who ever suffer this isssue, imho, first place to contact is seller, not Siglent. Seller need handle this and seller seller cooperate with Siglent as/if nessessary and how need in different situations. This is main road - or least sales network need develop (and limit) so that it go to this way sooner or later. Better if yesterday..
If I have problem with my Sony TV I do not call Sony factory in Japan and I do not ask in some forum do I need really call Sony. In the old days there was no ambiguity about where to go if the purchased item was not ok.
