Anybody have any issues with their "Scale" encoder jumping/glitching around?
I have one of the earlier 5074s... Just started getting very "touchy" lately when scaling-up or down... Just wondering if the newer firmware did a better job of de-bouncing the encoder output?

Hi
Bit Bug.
I have the same problem on my MSO5074, the Horizontal Scale (Time Adjustment) keeps jumping non-linearly when turning the control, left and right.
Here is a set of photos of the internal part of the MSO5000 taken by Dave:
https://www.flickr.com/photos/eevblog/45756741562/in/photostream/I think the name for this component is Rotary Encoder, it seems that there are 12 identical parts in the MSO5000, all are SMD type, and with the same type of finish. I think that of all of them, H-SCALE is the most used, maybe that's the reason it's failing, and it could get worse.
Dave made a video and disassembled a Rotary Encoder:
On Aliexpress I found a similar Rotary Encoder, from ALPS model EC11J1524413, but the finish is not exactly the same as the one used in the MSO5000, I don't know how many positions it uses in the MSO5000, and also the Axis Length.
If the Original Part has a Manufacturing Code printed on it, it will be easier to find it, or a similar one.
See the detail in the corners of the ALPS piece:

As long as you do not replace the defective part, you can change the H-SCALE using the TOUCH SCREEN on the screen, in the upper left corner.
This here is a specific topic for MSO5000 Hack, so that we can analyze the solution to the defect in more depth, and how it was you who gave the idea to the subject,
I suggest that you open a NEW specific TOPIC for discussion:
