content: Announced 6 days ago:http://www.hantek.com/english/news_list.asp?unid=40= the DDS-3X25 repackaged.I guess Hantek thinks this horse still has legs - but the question is: does it come with Goltek software, Mechatrommer?

content: duh! i'm dissapointed. why? few points...1) i expect this is to be a stand alone unit. wrong! another pc based fg?2) ok fair, by the name of it... 1025, i thought they managed to view and implement my hack so they can provide ±10V output amplitude. wrong again! still ±3.5V3)"25Mz arbitrary waveform output"wtf is Mz?4) the cd driver showing pc-based DSO. they have lazy guy working in their company.on the good side though, our 3x25 still wont look that badalum. casing? i have that for my external HDD if i'm really that desperate i can rip that apart and mod the 3x25 to 10x25-Aland about the goltek, its "open binary" so anybody who bought the 1025 may test whether there's FW change or simply an exact 100% duplicate.

content: I think it's the exact same device - on a slightly modified PCB. I'm sure they didn't put any extra work into firmware/software.Probably the massive DDS-3X25 thread here on EEVBlog - and everyone's hacking efforts (especially you) - breathed new life into a product that had been nearing the end.

content: IF i ever recall, the DDS-3x25 is discontinued though hundreds of thousands of them are still lying aroundBut this is essentially a DDS-3x25 in new Hantek packaging... I like seeing them in aluminium though. Could be fun to try and find a 5.25" caseNote : The listed weight is exactly the same which leads to me to think they just copied and pasted the data, i doubt a aluminium case itself is 300gramsBesides that everything is exactly the same

Instead of the DIY cable one had to do for the DDS-3X25.

I quote:Excellent industrial design-the same anodised aluminium casing as iPad, which is not only beautiful and tasteful but also greatly enhanced the hardness of aluminum alloy surface, and has good heat resistance and strong wearability.

content: LOL with that!I don't think i want iPad-ish aluminium though, i would probably scratch it everytime i lifted it off the table! Heat resistant ... is that the reason why the iPad 3 has such a massive surface and still feels hot as hell when using it?I prefer 4130 alloy aluminium, tough as hell.On the price side it's a bit pricey compared to the original 3x25 so no thanks but prices will come down

content: yeah unfortunately i dont have a need (and money) for that now. if BaW figure is right... 1025 is $244, lets round off to $250. 3x25 is $150, with $100 difference, you can buy another cheapo logic analyzer or something. i can even recommend the $15 FG on the other thread if you dont need the arbitrary feature, and buy your GF beers for many times. the sensible upgrade for me after the 3x25 is a standalone unit, not another ipad casing 3x25, not an empty reply when you send email "please send me full doc of the API i can develop for you for free". someone must hate me for this kind of advice but well, sorry "i cannot satisfy everybody" and i'm not politician. YMMV.

content: Fairly expensive new clothes, methinks, and it would be good to know how much of its resurrection was related to eevblog and Mecha's good work.http://www.hantek.com/english/news_list.asp?unid=13http://www.hantek.com/english/news_list.asp?unid=40What remains of old stock 3x25 are fairly scarce, I just checked taobao and eBay USA, so if anyone is interested get it before it disappears completely.

content: Quote from: Mechatrommer on November 05, 2012, 09:48:57 amI'm thinking about picking one of these up, the dds-3x25 that is. My question is; will your mod work with any version of the firmware? I would like to know before purchasing.

content: Quote from: tlu on November 05, 2012, 07:14:09 pmthe only way to know is:1) buy one and test.2) email hanteki dont think "soasystem engineering" will support or upgrade the goltek software in case of incompatibility.unless "MAYBE" if someone kind enough to send one test unit to Malaysia

content: IIRC there was never a firmware upgrade to the 3x25, just desktop software. So, the odds favor if you get one it will work with mecha's software.For $100 more, the new chassis and USBxi[ what is it anyway? Can't find any data on it except from Hantek products] :

content: yeah i forgot the point saturation mentioned. another way to test it is, download the 1025 software and see if it works on 3x25. if it is, you should bet goltek should be compatible with 1025, but dont blame me if you lose the bet.

content: it is the same device (oh well, maybe with very few changes). What's more curious is the even "newer" stand alone AWGhttp://www.hantek.com.cn/english/produce_list.asp?unid=156It looks for me like something i already saw before,wasn't that Siglent?Ehm f* .. wondering why Hantek announced a YEAR agonew gears (and there was a nice AWG on the list, check herehttps://www.eevblog.com/forum/product-reviews-photos-and-discussion/new-hantek-gears-released/)and now they producing just another one "crap clone"EDIT: haha, no, it's famous Gongchang One Hung Low Limited (functionality) MFG3000CH series AWG:http://product.ch.gongchang.com/d507418739.htmlOh well, i hope only that Hantek bought Gongchang (which is probably not the case, there are others selling exact the sameGongchang AWG out there, and well why to buy a company when you can only rebadge products) and not just re-sellingrebadged crap.

content: Quote from: saturation on November 05, 2012, 10:45:53 pmI'm also guessing that USBxi is exactly the same bus as the "Multiprocessor Link" on the DDS-3X25 - just renamed.
