Rigol DS1054Z rotary encoder mod *works!*
<< < (9/28) > >>
JohnPen:
Surely the wise thing to do is after a few months of fairly intensive use and you feel confident then pick up the soldering iron and do modifications.  If after those original few months of use you no longer feel it necessary don't do any modifications.  My view of this modification is that I will consider it for the future as I do agree the delivered encoder could be improved upon.  This mod does provide a useful way of avoiding a slightly annoying finger trouble for those of us with larger fingers!  With regard to the fan mod, as it was mentioned, just holding your hand to the left side of the scope creates a large drop in noise level if you deflect the airflow to the rear so one could improve things without opening the case.  Not necessarily a pretty solution though!

Regarding the throw away 'Crap scope'  obviously some have money to burn I do not.  This scope provides so much for the price range and is not really intended for high level professional use.  If you have a burning need for more precision then you pay the price but look at what you can do with this scope and be happy.

I own one of these too.  I have twin 16 months old girls.  Believe me, I don't have money to burn.  It fits what I need at a great price. I'm going to stand by my statement though...it's kind of a crappy scope. If I was back in a real lab, I probably would have flung it across the room on day one out of frustration...much of it centered around how alternately touchy and sluggish the knobs are.  They did a TERRIBLE job on that interaction. I can't imagine they can't fix most of this in the firmware. Doesn't anyone over at Rigol know how to do proper velocity/acceleration control interactions? It's really stupid that they behave like this.  Sometimes it takes dozens of turns to get to where I'm going, and other times I breathe heavy and the pointer moves. Come on.

But for less than $400, it's an amazing steal, especially considering the display which is VERY good IMHO, and for occasional/hobbyist/light/whatever use, there's just nothing else like it anywhere near this price range...but I'm not going to worry about some stupid warranty on it, especially if it makes working with it easier.

Encoder velocity control is just a few lines of code in a home PIC/AVR based project. So no, they do not know. And yes, they are stupid.
SimonD:
Hi Bud,
because i' m very interested about this application (encoder velocity) and appears to have dealt with it,
is it easy to give an example for PIC ? (or the idea behind that ?)
Thanks in advance
Simon

I was going to suggest putting an AVR between the encoder and their PCB to add acceleration yourself, but that still doesn't guarantee that their code is polling the encoder fast enough for that to work.  |O
