Rigol DS1054Z rotary encoder mod *works!*
<< < (18/28) > >>
StormJunkie:
Are the detents stronger/more solid on the ALPs enocders?    I'd prefer a more solid feel if they offer it...and if I'm going in any way, why not do them anyway.  I agree that replacing the trigger and position pots doesn't make much sense.  So I should have only asked if the menu select, horizontal, and vertical are the  same.

Thanks for the help!

They might indeed be a bit more pronounced on the ALPS encoder. But I can't say for sure, since I have never tried to swap large vs. small knobs: The larger knobs on the horizontal and vertical scale give you a bit more torque, and that will certainly contribute to making the detents feel softer.

I would say that the build quality of the stock encoders actually looks better than the recommended ALPS encoder: Metal body vs. plastic, and the axis feels a bit more precise (wobbles less if you wiggle it sideways). So I would leave the scale encoders unchanged. Coming from an old analog scope, I also thought that the scale knobs felt a bit too soft initially, but I got used to it very quickly. The detents are certainly strong enough to give you a clear haptic feedback on the steps.

I am also planning to replace the encoder on my DS1054Z. Its behaviour is now completely erratic!

I first thought to use the "ALPS EC12E2424407" used by Howardlong (below, August 23, 2015) but, on mouser, the part is obsolete and, on Farnell, it gets two reviews, both bad (http://uk.farnell.com/alps/ec12e2424407/encoder-vertical-24-det-24ppr/dp/1520813).

I then tried to find the exact reference of the EC11 which worked for you. There are many choices and I am a bit lost... The best match I found with your description is the "ALPS EC11E15244G1", datasheet: http://www.mouser.com/ds/2/15/EC11-951851.pdf

The shaft is in metal and it seems more robust.

But I am a bit reluctant to buy it (especially because of the shipping cost) without being sure that it will work. Anyone has opinion and help me make my choice?

Thanks!
Fungus:
Has anybody done a step by step guide to doing this?

How many screws do we need to remove, how hard is it to desolder, etc.

What's the chances of messing it up?
cowana:
The EC12E2424407 which people have successully used is 24 detents, 24 pulses.

The EC11E15244G1 you suggest is 30 detent, 15 pulses. While 30 vs 24 is not an issue (menus will scroll through slightly faster), the detent:pulse ratio is - unless it is also 1:1, you'll need to turn the knob two clicks per change.
