Please look at the scope I just linked to in my previous post.
I want to be able to check for issues related to wiring, distance, and the optimal resistor network values to put in the outputs. I want to be empowered with enough knowledge to know what I am looking at to see if there is a problem. I am trying to use it to troubleshoot communications between a controller like the e682 and WS2811 pixels. I have spent so much time reading online buying guides that all sum up with the same thing "What are you using it for?" and unfortunately I have been unable to find any resources that talk about oscope requirements specific to pixels. Thank you Martin, these are the kind of leading questions that I need to be asked. Hopefully that clarifies things, perhaps you can give me some guidance based on what I have said.Ģ014 Contestant on ABC's "The Great Christmas Light Fight" Lastly, once I have the thing in hand how do I learn what I am looking for specifically with pixel communication? I have never seen a tutorial or anything on using an oscope to troubleshoot for our hobby and I do not want to waste time reading or watching videos on using an oscope in a totally different application that does not at all apply to how I am using it.Īnyway, I was looking at this one, what do you think of it? W One buying guide said to buy at least 2x the speed you need (so if e1.31 is running at 100Mhz do I need an Oscope that can do 200Mhz?) Our pixel speeds are running at 40ms and up (not sure how to convert this to necessary Mhz)Ģ. Here is what I know but not sure how to apply to product selection:ġ. Well the problem is that I do not know anyone in this hobby who uses an oscope so I do not know what specifications are necessary for what we do. However I am not sure when looking at these what the probes support because they do not say or they just say '1x - 10x' which I am not sure what that means.Īnyway, the real issue is applying all the knowledge out there to on oscope selection to what my application is (troubleshooting e1.31 or DMX or whatever) Almost all the buying guides say to start first with identifying what you need it for.
I read an article on purchasing one and it said to beware of the speed being advertised at 100Mhz if the probes can only support a fraction of that. Now after being asked that question I want to get one just for my own personal education. I am working with a company doing some troubleshooting at a major entertainment park and they asked me if I had one that I could take on-site to troubleshoot some communication issues. I want to learn though how to troubleshoot signal issues between the controller and the pixels. I do not know what I am looking at with the o-scope.
