I just purchased an used Rigol DS2102 that has full function for a pretty decent price.
Got the unit in today and so far I am very happy with it but I do have an issue...
The intensity multi function knob broke during transit or packing and it's not in the box.
I have been searching very hard to find some where that will sell or part out a junk oscilloscope to no luck..
Does anyone know of a source or a fix.
I have contacted Rigol but have not heard back from them yet.
Many thanks to all for your help.

Matching knobs are hard to find. A flea market (even ebay "parts only" listings) or hamfest might have something. You might contact Rigol's authorized dealer for wherever you are.

One of the popular mods for the Rigol scopes is to replace that encoder with an encoder with detents. That often forces use of a different knob anyway.
