content: FancyFor sure, the form factor, interface socket-arrangement do seem very similar to Rigol's current entry lineup, just with an Owon kinked UI.

content: Quote from: ptluis on April 16, 2025, 10:40:02 amNot sure. Sampling rate is better than the Rigol (DHO800/900).Rigol has:625 MSa/s (dual-channel)312.5 MSa/s (full-channel)Owon has:1.25 GSa/s (dual-channel)625 MSa/s (full-channel)Quote from: ptluis on April 16, 2025, 10:40:02 amI was wondering the same thing.

content: Quote from: ptluis on April 16, 2025, 10:40:02 amI think that's a mistake.This function is probably only available in the ADS900A with optional AWG (or with an external FG?).https://www.owon.com.hk/products_ads900a_series_12bits_multifunction_digital_oscilloscope

content: Quote from: Aldo22 on April 16, 2025, 10:53:59 amI don't think we can trust the user manual. On owon website they write 625MSa/s (dual-channel), and full channel is 6250MSa/s（full-channel）!!!Companies don't worry much about this kind of error these days. Is it too expensive to pay someone competent to write the correct information? Anyway, I sent them an email. Let's see if I ever get a response.check here and check for yourselfhttps://www.owon.com.hk/products_ads800a_series_12bits_digital_oscilloscope

content: Quote from: Aldo22 on April 16, 2025, 01:00:45 pmComparing both manuals:Owon ADS800A = 2GB system RamRigol DHO800 = 4GB RamIf the specs on Owon are correct 2GB Ram seems to low for multi window mode if that's possible.Look like a clone of Rigol? maybe, maybe not. Proper reviews are needed.

content: Quote from: ptluis on April 16, 2025, 04:16:07 pmTons of similarities in the case, but, not a 1:1 copy.They went with yellow/orange instead of turquoise/blue, gotta have two similar channel colors.

content: Quote from: thm_w on April 16, 2025, 10:05:56 pmI was referring to specs and interface not the case. If Owon clone the case they immediately suffer a law suit.

content: Wow Owon ADS800A/ADS900A are very similar to Rigol DHO800/900. If someone told me that this models are a rebrand of Rigol model, I would believe him. Control layout and colors aside, they are 1:1 with Rigol. Almost same dimensions, connections type and place (USB C powered, HDMI...) and almost same specs... just enough differences to avoid be sued.Aside of that, they look promising:- I like they take advantage of the entire screen. No useless logo in 7" screen. Color scheme it's fine and the texts are clear.- They are cheaper than Rigol DHO800/900 and theirs specifications are equals or better.- Interesting ADS900A series. 2G/s and 100MptsAll that's left is for someone make a review and check that they meet the specifications and how responsiveness they are.

content: I've found a short video where someone disassemble the ADS924A, the components vary significantly compared to the Rigol DHO800/900. They seem to have two ADCs.Maybe that makes sense since for the ADS800A with 2 channels active it can maintains 1.25GSa/s.https://www.youtube.com/shorts/gBUQlmmF9S0?feature=share

content: hmm at least no sd cardfor looks I think they all just mimic one another as such scope design is kinda trendy nowadaysalso Rigol has a vesa mount and here I do not see it (I would love to have it in Siglent scopes)is there a battery option that was kinda "traditional" for Owon?

content: They don't seem to be directly sold in North America, or not much is showing up in the search. But if they do what they are rated for, then I'd say great, the more people that can afford a modern scope, the better.
