hmm.... my SDS8102 arrived in a version : V1.0.1. May be i need to check for updates from Owon. See if there is any update.

There is not public loadable FW updates.
No, afaik, update is by USB. Becouse end user can do it. Owon can send it to customer. Many end users have also buy directly from Owon. (also distributor is customer )
But they really do not always new FW hurry and hurry... you look Hantek. Just after FW update new update and some updates very loose done and new bugs and old bugs... most I like personally product what do not need always update after update. There need be wise developers who collect all repair and development needs and then carefully do it.
Owon FW is very clean from bugs (but also littlebit less features and extra dingle dongles) if compare Hantek where today is bug behind every corner. FW is neraly like mixed spaghetti after these "programmers" who do all just now and quickly and just as try-fail-try method. Pawns can write Feynman book if they try enough time.
I think this all is becouse B.Gates have born.

1 VLED+ P Power for LED backlight anode Pink
2 VLED- P Power for LED backlight cathode White
LED backlighted TFT
And this is really good news! (Manufacturer well known Innolux, LED backlight)
Yes, but correct information is: Owon have Led backlighted TFT, not CCFL.
in specs 20000 is minimum. Not typical. And 50%. 50% is not much of.
Yes, it is good news.
compared to CCFL, LED only decay byt typically do not wear out like CCFL
50% 8.2V good setup value for normal use 50 - 80%
0% 7.35V (still can use in dim room.)
Only more reliability.
Quote0% 7.35V (still can use in dim room.)Then you have MUCH lower standards than me in terms of display brightness.
Btw... there was some misunderstooding becouse my language. as dim... dimmed..
(bias, just as hitachi... all do it)
But I have to say, I don't like Owon's choices of screen colors or font - and that they don't give you a method to control the relative brightness (or change the color) of the graticule - it's either on or off - and I feel it's too strong in comparison to the other elements on the screen. But of course, these are all things that could be fixed/added in updated firmware.
But you know, it's so odd that the display of the Owon is higher resolution then the one on the new Agilent X series (and the quality level is probably equal or better), but it looks so crappy compared side by side to the Agilent, because of bad visual design. Most of these Chinese manufacturers need to hire some GOOD visual designers - because their screen layouts, colors, fonts - sometimes even the product design itself - makes them LOOK cheap - and there's no reason it has to be that way - it's one of the easiest things to fix.
When I was a kid back in the '60s, no one took Japanese products very seriously because, even if they were well-made, they LOOKED cheap. But the Japanese learned this lesson quickly, followed later by the Koreans. Now it's China's turn.
But example scope... it can not do good useability if designer do not really have know-how and experience about measuring routines. There need be one "old guy" who know. But then there is also one tuth... all can not make happy. You do young hobbyists happy you loose professionals and wice versa. You can try both... many have try. I do not know any who have win this. So first they need select what side river they stand.

This is true. But even so, once they have tried to develop a good interface, structure, menu layout, etc, they need at least one clever person with sharp visual design skills to look at it when finished and say, for example, 'No, it's not clean looking to have a san serif font printed on the front panel, but then a font with serifs on the LCD. In fact, fonts with serifs don't look very good on LCDs because the low resolution can make them look too big." ...Things like that.
ME: Thank you very much for your reply [regarding authorized resellers]. I wish to ask further questions regarding the firmware of Owon units. How often do firmware updates get released for the SDS models? and how would I receive these updates? would they be sent directly from Owon via email or is there a download site to obtain these? I have read some excellent reviews regarding the SDS7102, but those people also commented that some features of the firmware need improvement, and I would expect that Owon would periodically release updates to improve their already excellent product. I just want to understand how the update process takes place.
MR LEE:
Thank you for reply.
If a product needs to add functions or need to solve a bug, the firmware needs to be updated, it is right, but before selling our products, we already shape our products in good condition, so there is not promising to updated firmware often
If a product needs update firmware often, we can regard that it is not a mature product, is it?
If our products need update, we can send software to you via email, and you could operate update by yourself.
Kindly regards,
Mr. Colin Lee
MR LEE:
After viewing, the man gave his opinion such as how to better design menu and show data in display, and also point out the features such as big LCD display, 10M record length, VGA Port etc.
After all, we think we have not plan to add the functions the man need recently, because we regard this unit as mature products. Unlike other brand scope need to update firmware time by time.
ME: ...how do we go about obtaining firmware updates for this scope? Will Owon release these updates to you, then we can get notified by email? From everything I have researched, the Owon is a great scope, but some of the firmware features need lots of work, so I would assume the manufacturer will be releasing updated firmware occasionally. I don't see anywhere on owon.com.cn to download firmware, and have read that Owon has a bad track record for publicly releasing firmware updates.
Al MacRobbie:
I found from OWON today that F/W upgrades are not, at least for the present, going to be made available to the general public. OWON factory-authorized service centers (like Saelig Company) are to perform upgrades as a service to our customers.
It is a shame that some of these manufacturers don't realize the value that can be had from releasing an open-sourced version of their hardware.
In the radio-controlled model market, one manufacturer (FlySky) has an 8-channel RC system (Atmel based) which comes with pretty crappy software -- adequate but really not using all the processor power available and delivering only minimal, partly-implemented features. A couple of guys have developed their own much better firmware for these RC sets and the result is that they now perform as well as products costing four times as six or seven times the price.
As a result, lots of people are buying the radios and reflashing them with the new code.
The benefit for the manufacturer is that they no longer have to fix the bugs (not that they were bothering to do so anyway) because those who find the software bugs a problem can simply reflash to one of the better open-sourced versions -- and the product now has a much greater appeal because its capabilities are effectively doubled.
So long as a scope company isn't deliberately ankle-tapping its hardware by way of the firmware (like the Rigol) then there's surely nothing to lose by selling it with whatever documentation is required for others to write their own open-source (or proprietary) code.
Software seems to be the Archiles heel of many Chinese manufacturer so why not avoid a whole lot of hassle and allow users to fix/rewrite the damned stuff themselves?
(Hope this isn't too off-topic... it's in reply to what RCMR said)
I absolutely agree, RCMR. So what would it involve for several EE's to get together and design an open-hardware scope? There are several projects out there which are partially open, for example DPScope (dpscope.com) (open hardware, closed source software and firmware), bitscope.com, etc...
