Rigol DS1054Z rotary encoder mod *works!*
tablatronix:
I wonder could you 3d print (might actually need laser cut or cnc for the size) a pressfit 2 piece notched slip ring to augment the physical knob, to get around the pesky void warranty issue.
I guess you could kludge an existing encoder detent ring onto the knob itself even...
edit:
indexing detent knobs, hmm

How many screws do we need to remove, how hard is it to desolder, etc.
What's the chances of messing it up?

It's not particularly hard, but ISTR I found you need a pretty meaty iron to get the existing encoder off. Chances of messing up aren't high as long as your soldering skills are reasonable and you don't lose too many screws.
rstofer:
Desoldering is where PCBs are destroyed. I don't recall having any problem removing the encoder but I have a vacuum desoldering tool. Where I usually get into trouble is using SolderWick. Too much heat, traces lifting, etc.
I just looked up the datasheet and it seems that the pins are all exposed around the perimeter of the encoder. Cut all the pins and the two mounting tabs, remove the body and then unsolder each pin one at a time. Then clean up the through-holes and mount the new encoder.
I bought extras but I'll be darned if I can find them and, short of opening up the scope, I can't recall exactly how difficult the encoder was to remove. What little I remember is that is was simple.
Work carefully and everything should work out fine.

Thank you Cowana!
I guess that I will stick with the EC12E2424407. I do not see any EC11 part with a 1:1 detent:pulse ratio.
The desoldering part is also making me nervous. I will follow the suggestion of rstofer to cut the pins and remove them one by one.

Hi there,
today I installed my ordered rotary encoder (Alps STEC12E08 24 impulses with 24 detents, which is already used by many) in the DS1054z (Mode to DS1104z).
First had to find out that the Rigol button / encoder board was changed.
All rotary encoders are now surface mounted. This means that there are no more holes.
Ok, modified the new Alps so that it was on the back plan, unsoldered the original and installed the Alps exactly positioned.
So far everything is ok, but the detents do not match the impulses.
Especially in longer menu lists, you notice that one menu point is often skipped per rest.
Could it be that in the last update the behavior on the encoder was changed so that this Alps is no longer read correctly?
