ADS-3102A - This is a rebadged Siglent SDS1102 it looks like. Not a bad scope (at least that I know of) but the Rigol DS1054Z is hackable to better functionality and as a result is a better value.3. DS1052E is VERY antiquated, it is not worth the money anymore. Much better to save a bit extra and get the DS1054Z.

content: Unlike the Rigols that have had every bug listed on this forum in excruciating detail, I am yet to find a bug in my Owon SDS7102V. Having said that, the feature list of the Rigols are much longer than the Owon for the same money, if you can get them all to work.

They've been my biggest seller in my marketplace.http://www.siglentamerica.com/pdxx.aspx?id=27&T=2&tid=1

content: Quote from: tautech on March 22, 2016, 09:00:00 pmIt seems like maybe the SDS1102X gives you more scope for only a little bit more money? That's the one I've been hovering over the buy button on all day but keep waffling thinking I should just get the 1054Z because everyone has it and it'll be fine. I've watched Dave's video on the Siglent though several times and even the interview he did with the CEO. I'm thinking I'd like to go with the Siglent but I don't want to make a stupid decision. Is there a reason you would suggest that SDS1102CML over the X?EDIT:Actually I'm even seeing the 1202X-S for a pretty good price online which has the waveform generator, though I can't find any videos about how that functions.I've got my 500$ gift card from VW for the TDI debacle burning a hole and am thinking I could finally get a scope I've always wanted to replace/supplement my 20Mhz analog.

content: Quote from: firworks on March 24, 2016, 03:07:35 amOnly price, thinking it's your first DSO and it'd save you a few bucks. BTW the 100 MHz CML is my biggest seller.But you're quite right the X series, not only is it a much more modern design but a more capable beast.For the few I've sold buyers have been pleased with them. I'll add these buyers have had other DSO/CRO's before and have had expectations of performance to satisfy which the SDS1kX series has.Is there further info you require, maybe we could provide a link.Best wishes for your decision.

content: This will be the first DSO I own but I've used quite a few DSOs over the years both in college and now in industry. They've all been very expensive Tek and Agilent scopes though that I don't need nor can I afford for home use. Your mentioning that the SDS1000X series has better performance is intriguing. Have you used them enough to compare against the reigning champ around here 1054Z? Is the UI generally more responsive on one over the other? Obviously the 1054Z has the advantage in having two extra channels, but I'm not sure how important that would be. Extra channels would be a nicety but not a necessity.Also asliyucegsm sorry for somewhat hijacking your thread. Hopefully this discussion is useful to you as well trying to decide on a scope?

content: Quote from: firworks on March 24, 2016, 03:58:44 amHow to answer that on this forum I'm not sure, other than to say I have not used a 1054Z.I did mean the SDS1kX series has better performance than the CML series, just in case you misinterpreted my comments.I know of no problems with the SDS1kX series UI.If you've been lurking here a while and taking notice of things Yaigol (Google it), you might have second thoughts.All I can do is offer info, to do more would be bad form so you'll have to make the decision for yourself.Most of the SDS1kX series technical atributes are examined by rf-loop in this thread:https://www.eevblog.com/forum/testgear/siglent-sds1000x-series-oscilloscopes/Do take some time to study it.Further guidance if you can ignore the high noise floorhttps://www.eevblog.com/forum/testgear/should-i-buy-siglent-sds1202x-or-rigol-1054z/

content: Quote from: Karel on March 24, 2016, 07:24:43 amBullshit. There was one very unclear single case where we do not know whole truth.Just tell honestly it is used, second hand or what ever but do not claim it is new (if it is new, in original factory paackage untouched, just tell honestly what is this case you want sell it - example purchased accidentally or stolen or some other honest explanation).What is motivation to continue repeating this disinformation about problems to sell your second hand Siglent equipment.Also example my customers have sold some they old used Siglent's after they needs have changed.There is not any Siglent company origin problem to sell your used Siglent equipment where ever markets, not even in ebayshit. For Siglent is is totally nonsense if someone sell, destroy or give away free as gift his own used Siglent equipment Absolutely, not any problem. Who try tell other truth he do not know what he is talking or he is lying intentionally. Period.

AFAIK it has the same functionality as the other inbuilt AWG's in DSO's from Siglent and therefore any vids you can find on the AWG for the other models should help you get the picture.Member Performa01 reviewed the SDS2000 V2 FW AWG in this post:https://www.eevblog.com/forum/testgear/siglent-sds2000-new-v2-firmware/msg825340/#msg825340

The list is really quite short.Don't tell people they're useless and they'd be out of their mind to buy one, because... it's not true. It's a very sensible purchase (provided you know what the three bugs are).

content: Quote from: tautech on March 24, 2016, 05:25:34 amMost of the technical attributes? Only waveforms/s and noise! Noise is actually more interesting (I'm avoiding the word important here) than waveforms/s. There is so much more to a modern DSO than just noise. How about protocol decoding, FFT performance, saving screendumps, connectivity, PC software, overal ease of use, BUGS!, etc, etc.

content: Quote from: nctnico on March 24, 2016, 06:43:33 pmI actually meant more about the responsiveness of the UI, and how "well it works" kind of. Like the feel of using it to to testing. I've had to use a Fluke Scopemeter on machine before to do troubleshooting and while the performance stats on it aren't bad, it's very sluggish and frustrating to use. Everything is slow and choppy looking.

content: Well, here she is!So far seems to work really well, very responsive and it didn't take long to locate what I needed in the menus. The only standout disappointment is it is pretendously sluggish with the FFT up.Now to figure out why that power supply board I built last year appeared to be switching at the wrong frequency. Or even if it is actually switching too slow.

content: Hmm, that is either a very basic question, or you are after some specific detail which you did not spell out.There are many oscilloscope tutorials on the internet, which I would recommend as a starting point if you are new to oscilloscopes. I think this primer from Tektronix is quite good and comprehensive (need to enter an email address to download):http://info.tek.com/www-xyzs-of-oscilloscopes-primer.html. Or, shorter and with some helpful animations:https://learn.sparkfun.com/tutorials/how-to-use-an-oscilloscopeApologies if you already know all of these basics. If you are looking for something specific instead, please let us know what.
