I hate it when they can't be bothered to mention WHICH bugs were fixed, is it really that hard to do? A firmware update is always risky, is it worth the risk?
My 1025 has a bug that resets the external reference back to internal each time its powered up (but it still says it is using the external reference - even though it is not). Has this been fixed - Who knows?

It's great to see Siglent still supporting their older products, I can't complain. :-+
However the changelog is annoying. They did step their game up previously but are now seemingly going back to when changelog's were not a thing. Perhaps this is just that Chinese face-saving culture thing? Don't admit to anything perceived as bad, pretend it didn't happen, etc.
What I was quite surprised at is the calibration adjustment scripts being made available! (may require a login). After all the flim-flam I got from a couple of Siglent dealers in the forum last year :-DD (hey, I forgive you guys!) ;)

The risk is very very low, the main thing to consider is power loss so I never do them in storms.
Of the some hundreds I've done, never has one failed.

Not yet but it's going to be.

Edit
Let me add this automatic reversal to Internal reference applies to all Siglent AWG's and therefore any fix applied for SDG2kX models will most likely be rolled out into all the other Siglent AWG series. 800, 1000, 5000, 1kX, 2kX and 6kX as each firmware is revised with a new version.

Thanks for the response! I'm a little more wary than yourself with firmware updates though, I've bricked several MBs in the past but thankfully no test gear (yet). I don't want to start now - and the comments about failure when updating the Rigol DM3058E underlines the fact you cannot take it for granted (yes, you may laugh about that :) )
It's not the fallback to using the internal reference per se because I would expect it to do that if there were no external ref signal present. It's the fact that it does so when re-booted with the external ref active and it still erroniously reports it is using the external ref whilst actually it is using the internal reference. It can be difficult to actually diagnose it is doing this without performing some tests so I routinely need to remember to reset to internal ref, then change it back to external again in the settings.
