content: Hi,Has anyone tried the GA1122CAL+ 2-channel Digital Oscilloscope from ATTEN / Hantek / GRATTEN? I found it on eBay (only in USA) and AliExpress (world-wide) such as at "https://www.aliexpress.com/item/4-8-arrival-ATTEN-Digital-Storage-120MHz-Oscilloscope-Scopemeter-2Channels-1GSa-s-USB-7-TFT-LCD/32751294054.html"It sells for an incredibly low $300 and supposedly is 120MHz bandwidth, so it's very tempting but I can't find any mentions of it on the web!Cheers,Shervin.

content: Welcome to the forum.You might find some more information on these scopes by searching for the Siglent SDS 1000 CML+ (plus) series oscilloscopes which for the price I believe are not bad value based only on what I have read. My concerns would be that there are now newer and better models available and also the link you provided is in USD so that would be almost $400 AUD which would probably also exclude any warranty if shipped from overseas, somewhat risky business in my opinion.A slightly earlier but similar model being the SDS 1102 CML with less screen resolution in brand new condition sold this morning on Ebay AU for $215 + $18 postage, I happened to be watching the listing at the time it ended and was both signed in and tempted, this was a good indicator that there are still some realistic bargains around. Some but not all of the Atten, Gratten, Siglent and Digitech scopes are very similar if not the same, I believe Hantek are a separate and completely different company altogether and not associated with the previously mentioned group.

content: Thanks, I've built literally hundreds of electronics circuits over the past 25 years but haven't really been part of the online electronics community so far, I've just been too busy with life & other online communities.I mentioned Hantek because in an eBay listing "https://www.ebay.com//itm/222711827501" they don't mention any brand name at all but in the images it shows Hantek brand, for the same Oscilloscope as the other Chinese brands are selling, so it looks like Hantek is also rebadging this scope. That's why I'm surprised there's no reviews of it on the web, I guess there will be over time.I haven't looked at the Siglent scopes but that sounds really cheap! Yeah the GA1122CAL+ is around AUD$400 when you include shipping, and doesn't seem to come with any warranty at all. So it's definitely a risky purchase!

content: I also saw a similar but slightly older Hantek CRO on AliExpress at "https://www.aliexpress.com/item/Hantek-DSO5102P-Digital-Oscilloscope-100MHz-2Channels-1GSa-s-Real-Record-Length-1M-USB-PC-Handheld-Osciloscopio/32709218713.html", it has hundreds of 5 star reviews, but when I read the reviews there's about 100 comments about the shipping & handling, and only 1 comment about whether it works OK as an oscilloscope! Considering how highly technical an oscilloscope and the need for it is, I doubt those hundreds of feedback are real, because if they really bought the scope surely most of them would be judging it by the measurement behaviour & performance, not whether the packaging got scratched or not!I guess I'll stick to borrowing the Rigol scope at my techspace if I need to use a scope for now.

content: IIRC the GA1122CAL+ maybe a rebadged SDS1000CNL+ model, they only have 40Kpts memory depth.Siglent rebrand these for many resellers. The + denotes a later model with a higher res display and LAN connectivity.For a few bucks more a CML has 2Mpts memory depth but is otherwise the same scope.Trio in Oz might still have some otherwise you have to go with some Asian seller and take your chances.

content: Thanks for the info tautech. You're right, it would be wise to pay a bit extra for much more memory points. The SDS1072CML+ does look like great value:https://www.ebay.com.au/i/332440271447?rt=nc:-)

Good little scopes, I've sold dozens of the 100 MHz CML model.If you can stretch for a little $ more take a good look at the SDS1202X-E as they are a big next class up in performance and features.Still a CML will serve you well and hold some good value until you're ready to take another step up.
