content: Quote from: SimonM on June 11, 2021, 06:34:09 pmIt's clear that the Siglent is better, but .... it's also more expensive.It all comes down to price difference where you live. If the Siglent is more than 40% more (approx) than the Rigol then you need a very definite reason to buy the Siglent. In general use the Rigol is a very capable 'scope for the money.

content: A friend recently bought the DS1202Z-E and it's very impressive for it's cost, though the price difference between the SDS1202X-E and the DS1202Z-E is pocket money, so the obvious choice is the SDS1202X-E imho if you only want 2 channels.However I'm going for the SDS1104X-E, as it has 4 channels and dual ADC's (And has the option of adding a AWG and MSO later on)

content: Quote from: tautech on June 11, 2021, 10:42:36 pmI was looking at the MSO option but I have also come to the conclusion that a 4ch DSO has some advantages over the MSO:1. Checking signals on an i2c or spi bus "looks about right", then analog scope can confirm levels are OK;2. Extra channels from the MSO make the display more than a bit crowded;3. Looking at a serial bus vs a 16-bit bus is as well served by 4 channel as 16;4. Highly integrated chips don't generally hook up with a parallel bus - 4 channel is more than adequate.Rigol 4 channel 100MHz scope is slightly more expensive (£25) than the Siglent but the cost of adding the MSO is much cheaper (£180) and as well as the H/W there is no license required. The Rigol has 1 gs/s, 500 M/s and 250 M/s for 1, 2 or 4 channel so is closer to the -U version of Siglent. I'm not sure how they get to over 100Mhz with 4 channels running with only 2.5 or fewer samples - seems like guesswork. It has been commented before that sometimes paying a small premium for Siglent is justified.Rigol vs Siglent also comes down to preference of the user interface. I do like the side buttons on the Rigol and the selection of measurements, but also the soft buttons underneath on the Siglent. Both scopes seem to have crowded the screen on the LHS and RHS so that the waveforms are smaller than they need to be and (as I read it) no option to hide the soft menus? The two-channel Rigol has combined the vertical V/div control with a 2 button selection whereas the Siglent stays with two separate controls. When you see the Rigol power-up, you immediately see green lights under the blanked-off areas suggesting it takes advantage of a common circuit board and an overlay that restricts the design.There is a real danger that I may overthink the purchase and get more than what I need. That said I feel more comfortable with the Siglent 4 channel SDS1104X-E over the SDS1104X-U. In the US they aim for a $100 reduction but in the UK there is only a £50 premium. A scope is one of those things, where trying to economize now, can easily backfire later. When considering the price, where you buy it in the UK affects the total price (discount and delivery) so that has to be factored in too.Simon

content: Quote from: QuitButton on June 12, 2021, 03:54:28 pmThe price of the SAG1021I is high enough that it's just not worth it. It's currently $159 at Saelig, but the UNI-T UTG962 $152 from Amazon, is a 60 MHz generator (even though I'm skeptical it hits that target, it's actual capability is almost certainly more than the 25 MHz of the SAG1021I), and has two channels whilst the SAG1021I has only one. It's not clear whether it's controllable from the SDS-1104X-E for the purpose of doing Bode plots, though.The FY6900 is even less expensive (about $130 on Amazon) for 60 MHz, and is apparently also controllable from the SDS1104X-E. Seehttps://www.eevblog.com/forum/testgear/siglent-sds1104x-e-and-sds1204x-e-bode-plot-with-non-siglent-awg/?allFortunately, nothing says you have to buy the AWG immediately.

content: Quote from: kcbrown on June 13, 2021, 07:34:57 amIt clearly isn't controllable directly. That thread with using FY6900 with Siglent scope uses PC in a loop, and a piece of software.Which is great if you happen to already have them both, and you just want the functionality and you don't mind additional effort and equipment being used.Beauty of the Siglent scope + Siglent AWG (not only SAG, but also SDG1000X, 2000X, 6000X) is transparent work in FRA.It simply works. Just connect network or USB.How important is that to anybody, it's their choice.Some people might decide they don't need the FRA at all and that even a simple analog function generator is enough for them...

I use it frequently to set my preferred scope settings for instant recall with the Default key.

content: Quote from: 2N3055 on June 13, 2021, 08:23:35 amHrm, that's disappointing. Not surprising, but disappointing.QuoteThat's most certainly true. Though you might be able to use a Raspberry Pi as the "PC". I've no idea. I've never tried to use it.QuoteThat is most certainly true as well. Keep in mind that if you're willing to pay about $100 more, then you can get a standalone Siglent unit (the SDG830). It, too, is a single-channel unit. An additional $160 over the SAG1021I gets you the SDG1032X, which has two channels.Frankly, I'd spend the extra money up-front and go for a standalone solution like the SDG1032X. Not only will it be more capable, it'll be more flexible and it is not dependent upon a single scope make/model for its operation. It'll be useful to you even if you decide to move on to some other scope later on.QuoteYep. There are a number of options here, each with its own set of tradeoffs. If you don't need the FRA then the options open up enormously.

content: Quote from: tautech on June 13, 2021, 08:11:19 pmI have the spec sheet and the manual for X-E and X-U and for the small increase in price the X-E is a no-brainer (US is about $100 difference and here in the UK it's £50). The manual shows the menu on/off but the operation isn't described. It makes perfect sense that it turns the menu at the bottom on/off and it's close to that area too.I couldn't find anything to suggest that the X-U has less capable processing capability (it would have been nice to know that they didn't save a few cents on this) - I get it that the input is simplified and doesn't have a second sampling chip. At this price point sampling with two chips is cool. So pretty much sold on the idea of an X-E. I can see that the X-U will be an option if the budget was for 2 channels because it's a small increase to go to 4-channels.I get that there is a hack for setting it at 200MHz BW, perhaps there are downsides to doing that? I read that the supplied probes rated at 100MHz are actually quite good ones, so no need to rush to replace them even with the hack (I was nervous about doing it but if it's reversible, why not?).Simon

content: Quote from: SimonM on June 13, 2021, 11:58:58 pmThere is no downside to the hack and you get more than bandwidth--USB WiFi for one. There's also MSO (if you buy the adapter) and external AWG (if you buy one) but those options aren't too exciting. The included probes have excellent bandwidth, but I wouldn't call them 'good'. They're cheap-ish and not very durable, so I'd say they're 'OK'. Not that I am complaining--at the price of the scope they really can't include $200 worth of probes. You'll want to scour eBay for your own specific probes anyway--switchable 1X/10X probes are sort of amateur hour anyway.

content: Quote from: SimonM on June 13, 2021, 11:58:58 pmSimon, you have a good handle on specs and capabilities and certainly with X-U pricing little more than the 2ch 200 MHz SDS1202X-E it's a no brainer to get the 4ch X-U if the additional BW is not required. But the SDS1104X-E is a better spec'ed and more capable scope.I feel the X-U capabilities are only throttled back rather than a result of lesser HW although the likes of the missing webserver, Bode plot and lesser FFT specs matter to some however they are another $100 for the 4ch X-E but you also get the additional ADC and its additional714 Mpts of mem support.When using either there is no noticeable difference in performance for general scope use. One only needs to watch the sampling rate when all channels are active in a X-U at higher frequencies to keep an eye out for aliasing.

A first-time user may not notice for while, but those are all pretty handy if you think about them. For example, USB WiFi + webserver = way to safely float scope!

Today (Monday) I opted for the SDS1104X-E and it should be arriving tomorrow.UpdateArrived as expected yesterday (Tuesday). I had a brief "play" and I think they have done a good job with the SDS1000X-E series scopes. It has a fan that is always on which keeps the scope cool and you can tell by the exhaust temperature that it's required. It weighs (without leads/probes) over 2.4Kg, so that's almost 1.8Kg more than a Hantek - this surprised me. Good as it is to get "stuck in" with the manual, it will require more reading, for sure.Hantek RIP (02.06.2021 - 16.06.2021)Today (Wednesday) my Hantek DSO2D15 was posted back to Amazon UK. I also sent the 250MHz Hantek probe I ordered separately (because Hantek only provides one probe) back. Amazon notified me that both refunds should be with me in a few days (not going to be out of pocket). As they say (and Jack Yellon wrote), "Happy days are here again!"Simon

content: Hi everybody, this is my experience for anybody, who's making decision as I did few days ago:I chose Siglent and sent it back after few days. Now I'm waiting for Rigol (DS2202 in my case).I'm not sure, if Siglent I got was broken or not, but my piece had big vertical offset below 10mV scale on both channels and self calibration didn't fix it. In additions, it changed every time I switched a device on, independently I had quick calibration in menu set to on or off.Secondly, device acted as transmitter - I'm working on RF stuff primarily and when I switched Siglent on, all receiver band was disturbed. It went even worse, when I connected a probe - even layed on table only.FFT mode - as a one of reasons I choose this mark - had some problem too. There was permanent peak on low frequencies even I had input shorted.And there was more small things that made me disappointed.I have old second hand Rigol oscilloscope for many years and there's no problems like this. I hope, that new Rigol will be at least same quality - not like this Siglent toy.

content: Quote from: premek_k on January 24, 2022, 04:48:08 pmThat is a bit of funny story....If any scope has "toy" implementation of FFT that is older Rigols. They are good entry level scopes but FFT is not well made on those.What Siglent scope? What model?What was the offset, in numbers? At which V/div?Those are important pieces of information...FFT peak on low frequencies..... That is you, not understanding how FFT works. Sorry.Frequency of 0 Hz in FFT is representing any DC component (DC offset) in signal. Including DC offset from signal not being fully symmetrical and scope offset. And if you plot FFT in vertical log scale (dBV, dBuV, dBm) it will be visible.For instance if you feed the scope squarewave that is not symmetrical (say 10% duty cycle) that one will have large DC component. You will see thatSo please let us know which exact model of Siglent that was, and also if it was new. If it was new and offset was really bad, you should have sent it back for replacement. If it was used it might have been damaged.If offset was really bad, you could have seen that in FFT too...Also, I hope you didn't buy old Rigol DS2202 but current model Rigol DS2202A. That is a decent scope.FFT will still be much worse Than Siglent has.

content: QuoteExactly like in the topic, Siglent SDS1202X-E. Brand new.QuoteOfset usually started on 10mV range and differed every time i made a calibration or even restart a device. In best cases it was about 3 divs on 0.5mV range (about 1.5mV), in worse case the curve was totally off screen (more than 2mV). On higher ranges it came better, up to 10mV range, when it was almost zero. Meaning DC offset, of course. How I wrote, an old Rigol scope I have has no DC offset on any range, I assumed this behaviour here too.QuoteRoger that, but how I wrote, no signal was connected in these cases, I had a shorted inputs. In my opinion, it accidentally showed some kind of parazital DC offset of the scope.QuoteYes, I choose DS2202A. I know, that FFT isn't great, but in fact, firstly I choose a Siglent hoping to save some money on buying a spectrum analyzer.

content: Quote from: premek_k on January 25, 2022, 11:42:19 amThank you for the answers.You should have returned that scope for replacement. What you saw was some kind of defect.These scopes don't do that.That weird DC offset would definitely show on FFT as DC component, and with log vertical axis would be very visible. That explains that.As I said, DS2000A are decent little scopes. FFT is not very good, but as long you're fully aware and good with that....As for FFT on ANY scope replacing full SA, it's not gonna happen soon. SA have vastly better dynamic and frequency range and many specialized functions (line noise markers, for instance and all kinds of specialized measurements) that simply cannot be replaced with just scope with FFT. FFT on a scope can be useful in addition to SA, to cover lower frequencies SA won't cover and to do time/frequency domain correlation....

content: Thank you,2N3055, for yours reactions.To close this discussion - I'm almost sure, that my piece was broken. But scope came with calibration certificate, someone made a checks. I consulted this wierd things with local dealer and he assured me, that this behavior is not fault. I simply lost confidence in this brand. Generally I am conservative in this regard, I made exception in this case and it didn't turn out well.I realize, that scope FFT can't replace real SA functionality, I use it mostly only for quick look and I was expecting something more from Siglent, but it didn't offer me even a standard.In fact, I'm afraid Rigol won't disappoint me either...

DS2000A are actually scopes one step up from Rigol DS1202Z-E OP mentions. They have 2 GSa/s converter, and go up to 350 MHz, and have 56 Mpts of acquisition memory.Siglent model that goes against it is Siglent SDS2202X-E, and has few more protocols, color grading display and few more differences.
