Hi
Beatman
With this Rotary Encoder EN12HS1L code I did not find the datasheet.
I think that in this type of Rotary Encoder component, the External and Internal Parameters must be STANDARDIZED, and a cross-reference of brands and models will help everyone. Perhaps you can change the Height of the Axis, and its Format, but the Pitch and Functions are the same. This is better than nothing.
I think it's productive, if any of the participants have a DSO from Tektronix or Keysight or Teledyne-Lecroy or Rohde-Schuarz, which have a LIST OF PARTS, and Spare Parts, check the Original Rotary Encoder Code, and inform the link here in this Topic of the datasheet. And check if it is similar, and if it is easy to buy.
The defect in the Rotary Encoder on the MSO5000 may occur in any of the 12 positions on the MSO5000. It's a matter of time when symptoms appear...
I don't know if RIGOL can indicate to Brands the Rotary Encoder models that can be used, and also sell them at a low price to users.
If someone has the symptoms on the MSO5000 during the Warranty Period, they can uninstall the HACK and send it for Free Repair, if the warranty seal has not been broken. It means spending some time without your MSO5000.
