On several of my YT videos talking about this scope you've posted the same comment:
If you update to SP3 does it sort the problem out? I have just received my own Rigol fucking DS1054Z shit but all the posted hacks look pretty old. Your openings scare the shit out of me for my new oscilloscopy. Please view my own box-opening experience in pictures here: https://www.eevblog.com/forum/testgear/my-new-rigol-ds1054z-has-just-arrived-in-its-box/msg944321/#msg944321 and if you have any updates about that shit please feel free to discuss it there !?
Thanks for watching and commenting on my videos. No need to be scared, just be aware.
1. Since your scope appears to be new production and was delivered with the 00.04.03.SP2 firmware, it probably has a later Boot Version than the scopes that are subject to the Freeze Bug (Boot Version 0.0.1.2) , where the scope stops responding totally to any user input and must be rebooted and sometimes even reset to factory defaults to recover. So you don't have to worry about that one (probably).
To display your full System Information screen which shows your Boot Version and the rest of the installed Software suite, you have to do a keypress dance. Very rapidly press, in the Trigger section, Menu Menu Force Menu. Then quickly go to Utility>System>System Info and you should see the full System Information screen. If you don't get it the first time, keep trying, and press the button sequence faster.
2. As far as I am aware, the most recent firmware is version 00.04.03.02.03, which is identified by the scope as 00.04.03.SP2. I don't think that Rigol has released any "SP3" version.... yet. See the screenshot below which I just captured from the RigolNA website. We are waiting, Rigol.....
3. Putting the spring hooks onto the bare probe ends sometimes takes quite a bit of push to get them properly seated. There is a definite "click" when they snap into place.
Good luck with your new instrument! You have a nice workbench layout.
