content: I have one complaint about my new scope. When I mash the dial to select a value, it frequently changes the value prior to setting it.Any hacks/mods for making the detents stiffer?

content: I agree with superUnknown about loose detents when pushing a knob. I would also like to have stronger detents on main knob.Real solution would be to find identical size/functionality knob (it is not that simple too find exact match) and install it (voiding warranty at the same time).One thing you can do is to change a way you push a knob - place your palm on top of the scope, turn the knob to required position with index finger/thumb, hold knob in position with slightly bent index finger from the top, then push straight with the thumb.

Touch scope with you finger tips above Clear/Auto buttons.2) You should still have movement freedom for your index finger and thumb. The rest is easy.

content: I am yet to get one of these scopes, but did notice that it seemed rather hit andmiss in some of the video's that I have viewed, and also comments in the forum.My first thought was if the control knob simply pulled off without dis-assembly then a foam orsoft rubber washer or similar between the rear of the knob and the case may act as a brake.If it worked out, it could be an easy and quick remedy for some of those having trouble,obviously not the ideal solution as a firm indent would be better, but may be worth a try.Muttley

content: The Rigol Knob Swap.GDay tautech,Is this just the knob or the entire encoder assembly, my concern wouldbe voiding the warranty if it was the whole thing that had to be replaced.I do really need to get one of these scopes, not because I need it,but so I can stay in tune with what all you other people are up too.Muttley

content: MuttleyJust swap knobs with a larger one for better "feel".They just pull/push off/on.But really we are just having a it of fun....The ergonomics of the modern DSO are such that with the correct hand position there is NO problem.If the Firmware acceleration of the encoder is OK they work fine.Three fingers in top of scope for steadieness and control the MF knob with thumb & forefinger.Not sure about lefties though.
