Purchased a DS1054Z/DP712 and need advice

I have a bunch of times now but I still find myself having to double check before I hook up anything new for the first time  :palm: |O. I’m going assume it’s just  nerves and inexperience on my part

I’m extremely happy I’ve found this forum though as I really don’t have any friends or family in my life that understand or care about this kind of stuff. It’s definitely a huge help and I look forward to reading through the forum and experimenting with some of the new found knowledge!

DON'T - this is bad advice!

I didn't knew about the low range issue, the bit stretching was pretty obvious, and the self noise for sure, but not usuable at all haven't cross me yet.

--- Quote ---@JS - how long have you been using your scope?

Not long enough, for sure, I got it a short time ago and only made a few measurements I actually needed for real applications, pretty little play around to test things before to get used to the interface and that's it. Working with audio the lower range seemed useful to me as you are sometime playing with pretty low signals and even if it's only useful in long averaging might help to see things a bit bigger when offset is not the problem, I haven't really used yet.

This is not the first time I use a scope, and I'm very used to do post processing on the PC from the samples so I make a lot of my math there, being able to capture directly from matlab or octave in real time is really nice for me. Do whatever script I need there. Even then this scope has proven to be much better than the cheap lecroy we have on the university for most uses, every once in a while we get to use a better one but nothing too fancy or modern for general use.

I did used quite a bit of the digital decoding and will some more as soon as I grab a repair I have on the shelf of a PC controller for audio. Already fixed some of it but I think there are a few ICs on the thing still messing things. Non of this seen on the university, I think is something really missing there.

One thing I'm missing are the diff probes for which I've done some research but haven't find time to work on them, as there are too many applications as one single one won't cut it I rather experiment a bit and build a few than buuing one that only works for some applications. I work mostly on induatrial applications and some on audio gear. For industrial I would need an isolated probe for sure to measure power drivers and a differential probe I might buy for safety, so far I been getting away with a transformer as I mentioned. For audio some small CM low noise is required, 30V of CM is plenty, some gain like a 0.1X is nice mainly to avoid the 1mV/div on the scope so the noise of the scope is not a limiting factor. Nothing to do with high speed which makes them pretty DIY friendly. For the embedded side of things differential probes aren't so essential so I can live without them. Other problem I'm facing is some work on a boat, to hunt some noises but the reference of the boat isn't the mains earth reference but the water, so I'm not completely sure how to deal with that.

@ebastler If I'm missing something let me know, I'm always open to learn, I know I need a few things around my scope to be able to work confortably with it, way too many probes on the world to get them all, I'm just trying to figure out which ones I actually need. Too long so I leave it here. Thanks in advanced.

Hack it.  It's easy to clear.  I really don't think the manufacturer cares that much.  They have even sold it "hacked" at times.

I have the full three year warranty on the scope and it came with everything unlocked besides the 100MHz.

IMHO, Not worth the effort to unlock the 100MHz for guitar effects/audio amplifiers etc.

Adrian_Arg.:
I bought my rigol with all the licenses, except 100 mHz, I enabled them, and to prove it I went back to factory mode and I released it again. I did it by means of USB connection. It remains the same as DS1104z but with two 2 bit less. I am really very satisfied with the team, I use it in electronic and arduino project. I had a single problem with the equipment which was 100% solved with advice from the people of Rigol, after waiting a month or so for them to respond to my problem.
