Rigol DS1054Z rotary encoder mod *works!*
<< < (3/28) > >>
Tainer:
That's a very nice mod!  :-+ Another thing that I would do while still in there: increase the value of the current-limiting resistor for the red LED behind the 'start/stop'  button - imo it's way too bright and distracting.

Actually, I don't mind that encoder at all - while selecting values and stuff is not very comfortable, it's quite convenient for adjusting cursors, intensity, etc. I'm a bit more frustrated with the encoders with detents on this scope that tend to miss a step sometimes. The thing is - you can leave the knob is sort of a 'half-step' position and when you turn it you will actually feel the click, but the step won't be registered.

For me, moving cursors with the detented encoder is much nicer and accurate, good acceleration. And I don't like to select menu options using the soft keys. I always 'overshoot' the wanted menu option using the original encoder, like triggers or decoders. And if I got the right option and press the encoder for OK, it jumps one option up or down most of the time.
Now thats gone, 1 step on the rotary encoder is 1 jump in menus. Pushing the encoder button for OK never changes the value or option, selected item just stays there. Spinning it faster, steps are bigger. Changing values is better now too.

But thats my opinion.

BTW, the brightness auf the LED is ok for me. Fan sucks  :--
Ahh, and yes, I will cover the LEDs for SG and LA. Hey, I can see them for 1-2 sec at boot up  ;)

In that case I'll definitely consider this mod. They probably should have used a dented encoder for this knob in the first place, price difference couldn't be that significant. Can you give a link for the digikey part?
As for the fan - I wonder if it will be good enough to simply slow it down (i.e. put a series resistor with a fan).

Sorry, no partnumber for the encoder. I bought mine on ebay some time ago. Description only tells Alps EC11 or EC12 with dents value.
I will try to find out what part number matches.

But you can measure the original encoder with scope or LA to get the right one.

I will change the fan with a quieter one as described in other threads. A resistor will also help, but be sure the fan still starts at lower voltage. I know the stock fan is sucking the air through the scope from right to left, blowing through metal and plastic cutouts in the case. The 'air-noise' is higher than using this fan outside the case. I wonder if it is more quiet when changing the airflow direction.
Will try this later.

Nice to know that the knob can easily be replaced if the original one breaks.

But "not particularly hard" isn't the same as "easy". I bet you still occasionally manage to turn the knob 0.1 degrees when you're pushing it, giving a bad selection.

The whole thing has a ridiculously easy software fix IMHO - just allow people to press the grey menu button to accept a menu choice after you turn the knob.

(And bonus points for letting us move up/down inside a menu using the blue up/down arrow buttons).
