Rigol DS1054Z rotary encoder mod *works!*

<< < (12/28) > >>

Thanks to Howardlong and Penguin36 for finding the part number. Bought it weeks ago for 5 Pounds in UK. Today I finally had the time (and courage) to replace the encoder and it works like a charm. Unsoldering took some time and plenty of leaded solder.
Now that the fan is silenced with a resistor (6V instead of 12V) and the menu button annoyance is resolved, the scope is perfect (for me).

According to the warranty contract only "Repaired by anyone who is not from RIGOL Maintenance Center or an authorized maintenance branch" will void the warranty. So this means that opening up your scope and making modification to it does not void the warranty, because you are not repairing the equipment, you are making modifications to it. In fact, making modifications is protected under the Magnuson–Moss Warranty Act. They can only deny repair coverage if, they can prove, your modifications are the cause of the problem with the equipment.

I didn't really do anything other than affirm that Penguin36's mod works, and I was lucky enough to have the right encoders in stock. Interestingly, while using the scope recently I'd completely forgotten I'd done the mod, I'd become so used to it: it'd be interesting to see how I felt about the scope if I undid it again! Equally, I'd not even noticed the 0.55mm additional excursion of the knob either, so as a result I won't be filing it down now I guess.

I guess there's no harm in bumping this thread on a very helpful modification up again... Modified my DS1054Z today, with the same encoder suggested before (ALPS EC12E2424407). I can just second that the rotary knob is much easier to use for me now!

It's not just avoiding the sporadic additional step when pushing the button -- I had reasonable control over that, but it did happen often enough to be annyoing. But you also get nice haptic feedback when you want to rotate the knob a defined number of steps, e.g. when stepping down two channels while selecting the trigger input. Registering (counting?) the clicks happens totally unconsciously, but for me is much more pleasant than having to observe the display to see when the right selection has been reached.

On the other hand, the detents are subtle enough, so they don't become annoying when one has to rotate the knob several times. Overall, a highly recommended mod!

As a side note -- while I had the scope disassembled, I noticed that the screen is indeed protected by a glass plate, not plastic. I recall that this was debated in some other thread a while ago. A decent thickness too (approx. 2.5 mm), so Rigo did not skimp on this. Makes me feel better about having the scope directly on my desk, rather than on a shelf, while working with a soldering iron...

TheSteve:
I also did this mod to a 1074z-s - totally worth doing, especially with the AWG.
