content: I find this product interesting. A modern scope can be constructed on a single PCB so why not make use of this attribute and attach it to the back of an LCD display? As you are using a touch screen I do have one product suggestion, let the user have the ability to change the colors used by each channel (rather than use the standard yellow, blue, magenta, light blue).

content: Quote from: Rubi Han on February 05, 2015, 08:21:57 amMy idea is that it looks intriguing, but Micsig isn't going to generate much interest until they start answering some basic questions. This is just a re-hash of dropping a pebble in the pond that Micsig did 16 months ago. And nothing at all came out of that.Things like availability, MSRP, and which options are field-installed, vs. factory-only. And how much the options cost. And whether the many options advertised are actually available, or may only appear at some indefinite future date.rf-loop asked quite a few questions in this Forum last summer, and Micsig never responded to any of them. Micsig hasn't been forthcoming with answers, but has instead simply asked for reactions. This is just Phase3 of that same process, designed to generate discussion.You'd like people to talk about how great they these tablet-scopes might be, butno one has oneto examine it. You'll get vastly more commentary simply by providing one to a Forum member to review and get the ball rolling, than you ever will the way you've been proceeding. Check your PMs.

content: One frequent criticism of Micsig in previous bouts herewas that they didn't haveanydemo videos, showing off the device in operation.Well, they rectified that omission about 2 months ago, and now have 7 or 8 videos on YouTube, showing their tBook in action. They're mixed in with their handheld videos, but easy enough to pick out. Each is short, about a minute or so, and shows some element of the functionality:https://www.youtube.com/channel/UCu37SRPI8SaavIhzlXojEnANothing extended, but considerably better than what they had to show 16 months ago.

content: Quote from: Fsck on February 08, 2015, 03:11:08 pmThere's no full manual available yet (in English anyway), but there is aQuick-Start Guide, that contains most of what you may want to know about how the unit is operated. A slightly different version (dated 2015, and minus the Safety Info) is available onthe Micsig site.Also, Micsig has been updating their info on the tBooks recently, and over the past month a lot has changed on theirDownloads page. They even have firmware Updates directly available to their latest version (4.0.106). Interestingly, there are 12 different BINs, one for each of the variations currently available (100/150/200 MHz, 2/4-chan, A/non-A).One very positive sign is they seem to be focusing on the 3 performance levels they actually have available(?), and setting aside the 70/300/350/500/600/1GHz models for the moment. That suggests they are ready to sell what they have, rather than what they are planning.Lastly, there now seems to be several avenues available for actually purchasing them now. Batronix, as mentioned above already is one, and their offering already bundles some of the most attractive Options. They can also be purchased on AliExpress.com (cheapest unit with express shipping to the US under $1k), or ordered directly from Micsig, as Sample units.This last option may be interesting, since they currently are offering a 30% off incentive, on their Homepage. Of course, not knowing what any of the MSRPs are, for either the scopes or the options, makes it hard to evaluate what 30% off would be.I suppose it wouldn't hurt to ask, though Micsig really should be providing a Pricing Sheet. But people also need to know which options are only Initial Purchase, vs. field upgrades, vs. Factory upgrades. Micsig should try to start clarifying these questions.

If you want engineers to give your product any consideration, you have to be ready, willing, and able to respond to questions. Or havesomeonewho can. Otherwise, you may as well forget it.

It's really unfortunate that Siglent management is shooting themselves in the foot on the SDS2000 series, by not prioritizing the firmware improvements the unit needs, to match the quality of its hardware capabilities.QuoteThe tBook does offer the advantage of a full performance scope, running completely off battery. That can be a real plus in the field (or for mobile use on vehicles, e.g.).

Only few trigger types.Are these videos completely silent? Why?Here is another video made by a reseller. Oh, there is a microUSB. Why? Standard USB is more durable.Hey, this scope might have a powerful hardware, but for me it is just an expensive toy.What is that function generator icon on the start screen? Where is the output BNC?

content: Quote from: Hydrawerk on February 20, 2015, 08:21:32 pmLess than $900 is notcompletelyout of reach for a hobbyist, if they needed the portability + performance. But it's certainly not a casual purchase. However, who ever claimed it had to be priced for hobbyists? There are many professionals here in the EEVBlog Forums.QuoteAt this point, their Dealer network seems to be very limited, so probably not many could. And since they are currently lacking both distribution and dealers in many parts of the world, getting one serviced would be problematic enough to impede many purchases.QuoteThat model is ~$2400 US. It also has 4 channels, 90M depth (1chan, 45M for 2, 22.4M for all 4), 200 MHz BW, 2 GSa/s, and 500k wfms/s update rates. Sounds fairly competitive to me.QuoteYou really seem to be more interested in bashing it, than finding out anything about it. I'm unsure why. No search or markers,just like similar scopesfrom Rigol and Siglent. No segmented memory, that I could find. (Though they've got more than enough memory depth to support it later in a firmware update, if they decided to do so.) Why say "probably not" though, when you clearly don't know? Why not just ask, instead of bashing?QuoteIt's a portable device. It has a WiFi option instead. Not having a wired ethernet port does not make connectivity "poor". In spite of your assertion that it does.QuoteYou really are on a roll, aren't you? It does support Mask testing, according to their info, and triggers on Edges, Pulses, Runts, video, and numerous serial data streams. No mixed signal capabilities? Are you kidding? Where did it ever claim to be an MSO? Will you now bash every DSO ever made for having the same "failing"?QuoteYes. Possibly because they were made in China, and they had no English speakers handy to narrate them? One can only guess. Could you not see what was being demonstrated on the screen, w/o being told what that was?QuoteIt might? From your commentary, it sounded like complete junk.QuoteSo even if itdoeshave powerful hardware, to you it's a toy? Got it.QuoteIt's for, wait for it... a Function generator. The output BNCs are on the side, and the Option is only available on the 2-channel versions. On the 4-channel scopes, there is no room for another BNC output.Your belligerent attitude seems puzzling. Did someone from Micsig run over your dog or something? Your obvious animosity belies any possibility of an objective assessment of it's strengths or it's weaknesses. I think it has both, though I've seen nothing but their literature on it. It would be nice if someone got their hands on one to give some real feedback and commentary. I'd like to see how their touch-screen UI worked, and if it brought anything new to the table. Contrary to their claims, they're not the first or only ones to support touch.BTW, some of their promotional materials are quite amusing: "ultra-thin body", and describing it as a "tablet". In the sense that Moses came down from the mountain with the commandments on stone "tablets", I guess these scopes are tablets as well. But I would not describe 2.4-inches thick as "ultra-thin" in any way. Look at the tablet computers on the market, and 0.4" would be considered pretty chunky. Andyou'd have to stack 6 of those(!)to get something as thick as the Micsig tBooks. Holy mackerel!And the weight is "only" a 4 pound brick. That's far from a handheld device, which most would consider a tablet device to imply.BUT, that doesn't mean they're not portable, or potentially powerful and capable. And Micsig has another series of Handhelds, also with touch-screens, so they have that use-case covered. This is a scope you can grab and take with you anywhere, prop up, and start using with no power-cord. The stock battery lasts 4h+, and the optional battery does 8hrs (supposedly). That's saying something for a test instrument in this performance class. There are no knobs or switches to break or snap off, though the usability of the touch UI is something that remains to be seen/proven. Who knows? It may suck, or it may be really great.Unlike you though, I can't tell that without actually seeing and using one.

content: Oh, and Hydrawerk, one of your commentsI totally agree withis the placing of an XY Mode as an "Option". That really is ridiculous, and a poor decision on the part of Micsig. For no other reason than it's standard on even the cheapest scopes on the planet. And these aren't cheap.They've also been doing a poor job all along of discriminating between which features are Standard, and which are Options. They're starting to correct that now, but not all of their literature properly reflects it yet. That will do nothing but confuse potential customers, and generate negative feedback for them. Buyers will think they're getting certain functionality, find it missing, and discover it's an extra cost option. And NOT be pleased.In fact, Micsig is still unclear or being cagey about which options are Original Only, vs. Factory Installed Upgrades, vs. Field Upgrades. Or which Options are actually AVAILABLE now, vs. still under development. And no Price Lists for the options, so there's no way to evaluate cost comparisons. Ask them directly, and they won't provide them. I already have. They're not ready yet.These are all problems I'm sure they will eventually fix. They'llhaveto, if they want to sell them.

content: Looks interesting - the price seems high when you compare it to something like the new Rigols. It also seems to suffer from some of the errors/omissions that many Chinese products suffer from - so no BNC output on a 4-channel version?And from the video, the UI looks slow - which is one of my biggest pet peeves. And the screen looks pretty shitty - low resolution and washed out. Case looks kind of chintzy as well... and I think the lack of buttons means the UI has to be really good, and even then it would probably not get main usage for me, but might be a good backup and portable unit for field work.I would not consider buying one until I saw a review from someone - and it would have to be someone like Dave who has no skin in the game and is known for giving honest and unbiased reviews.I encourage Micsig to get one over to Dave for review. If it's great, they would probably sell many hundreds based on just that review. If it's shit, then at least they will have excellent feedback on where they need to improve.

content: Quote from: Hydrawerk on February 28, 2015, 09:13:23 pmHydra, I'd agree with both those statements. The problem here is two-fold: many Chinese products don't get a manual written (or translated) until after the scope is in distribution. Sometimes it takes a year or more before all the functionality is fully documented.Secondly, they don't have serial decode documented yet becausethey don't have it implemented yet. One of the unfortunate mistakes that Micsig has made on this series is to start out by promoting and advertising all the wonderful features and capabilities they plan on having,some day. That raises expectations to an unreasonable level, and results in disappointment when it is discovered that A, B, and C don't even exist yet. And there may not even be a definite date for them.Micsig is definitely learning as they go, and making some mistakes along the way. At least they've stopped promoting their 1 GHz bandwidth model, which doesn't exist, and may still be a year or more away. But be aware that their adverts and website describe significant functionality that someone buying one now WILL NOT GET. And whether they can just add it later or not is a, still unanswered, question.

When I contacted Micsig about the tBook, and using it for a serial decode project I had, I was directed to their Handheld series, which DOES support serial decode. Because their tBook does NOT (yet). That function is still under development.This is a problem I pointed out to Micsig a year and a half ago... their advertising of things that do not exist yet (potential future products, and capabilities), as if they already do. That may serve to generate interest, but is bound to lead to disappointed customers, or potential customers.There's nothing wrong with showing "future features", as long as you make it clear that they ARE future. Micsig has failed to do that, pretty consistently.

I look at the screen on the tBook and it looks blocky and low-res compared to tablets, even compared to the original iPad (132ppi). It's equal to what Agilent/Rigol offer in terms of PPI, but it's not an improvement.And in a few of the videos, the UI is slow. There is a significant delay from when the user is swiping their finger around and when the menus are opening and closing. My Rigol does that too when it's loaded down with tasks and it's frustrating.Again, not saying the Micsig is necessarily worse than others, but it doesn't seem to be any better - which is a shame when it's missing some important features and is higher priced, compared to those competitors.You said you are a sales rep for Micsig - have you talked to them about sending a unit to Dave for review? I would be very interested in hearing his opinion... I wouldn't risk $1,000USD of my own money on it until I had seen an unbiased review from someone I trust, and that would really be Dave (eevblog) or Mike (mikeselectricstuff).

content: As others have pointed out,Maybe you should send one to Dave for a review/teardown? But you should know by now that he is hard to please, he probably likes how much real state you have for the waveforms.The provided online documentation doesn't touch much on measurements and other things like serial decoding that for example the Rigol DS1000z series can do, but being battery powered is a big plus.If you decide to send Dave one, you should send the TO204A fully optioned specially with the 500K wfms/s and include the mouse so he can do measurements without being frustrated by the touch screen, also probably add the ground terminal so he can review that aspect as well.Of course the TO204A is over $2000 but the dual channel one seems to be around $1000, it's hard to find consistent pricing on the different models.The only detailed information I could find is here:http://www.dx.com/p/micsig-to202-10-1-full-touch-screen-200mhz-2-ch-tablet-digital-oscilloscope-blue-326711Even the micsig site pdf document doesn't show as much detail and I can't find any reviewshttp://www.micsig.com/Files/others/Tablet%20Oscilloscope_Product%20Introduction.pdfAlso the DX.com site mentions 5Gsps but I don't see any listed on micsig.com, maybe they are future versionsAnyways, if you feel your product can stand Dave's review and offers something others don't you should send him one.

content: Why not just make a front end with knobs, connectors and such drive a users own tablet? I've seen scads of USB scopes but I can't recall one that drives an Android or iOS tablet AND has buttons & knobs like a real scope.

content: Quote from: Corporate666 on March 02, 2015, 04:05:47 amI would have to agree with both. The resolution on the tBook is pretty good, as Rubi indicated. That 1024x600 on a 10.1-inch screen is partially control area, and partly display. The signal display portion is 18x10 divisions, with 900x500 pixels at 8.8" diagonal. Compared against the 14x8 divisions on the Rigol DS2000, with 700x400 signal-display pixels at 6.9" diagonal. Gaining 2-inches is a fairly sizable jump (28%) in screen-size and the visible amount of sample data.Corporate is also correct in that the latest gen of tablets has spoiled us. Not just in providing a welcome higher and smoother rez, but some so high they're bordering on ridiculous (e.g. the 9" kindle). And the PPI on the tBook is approximately 118, so about equal to the 116 PPI on the Rigol. Thus no change in detail (both 50 pixels/div).He considers that "blocky and low-res" on the Agilents and Rigols , as well. Just as he would the touch-screens on the $10k+ LeCroys and Rhode & Schwarz. (E.g., the hi-rez LeCroy HDO4000 with a 12.1" horizontal touch-screen and a $9k-20k price tag, is only 1280x800, at an even coarser 106 PPI. Even though the 12-bit acquisition there could actually take advantage of more vertical detail.)However, that doesn't mean that level of detail is required on an 8-bit scope, with an accuracy of 2% of FS. Any "smoother" waveform you might see on a super-high rez screen would be a fiction, created by the rendering software.

content: Quote from: Mark_O on March 01, 2015, 01:01:45 amI agree here. If functions are missing manufacturers should continue development before releasing a product. I think most people here got wary of products which aren't complete when released.

content: Quote from: Mark_O on March 02, 2015, 08:56:09 amI actually think it's shameful that so many of these scopes have such low-res screens. It's like what you see in CNC machines... they will sell a 512MB memory upgrade for $1,500 (yes, MB.. not GB). Many/most of these devices run CE, so putting in a higher res screen isn't that big a deal. At least for the Rigol, a lot of folks have complained that the text is too small. That's partly down to the choices the programmers made, but it's also about the lower res screen. If it was a higher resolution, they could make the smaller text look nicer with aliasing and have it smoother.One subject that's frequently kicked around at my work is unique selling points. We always try to make products that are better than what else is out there, as everyone should. I looked at the 100Mhz version of this scope in comparison to a Rigol DS2102. It is roughly equal on the main features with the Rigol - slightly ahead in some, slightly behind in others. But it's missing some things I think are important - although it is battery powered and portable so it has features some may find important. But I think a new manufacturer really has to offer a compelling case for users to buy their product, especially when they are the new kid on the block and don't have the reputation and history of Rigol/Tek/Agilent, nor the support network. This unit doesn't really seem to stand out in any major way, not like the DS2072 did (or the later DZ1054 that seems to be selling like hotcakes).Seems like Micsig has some reps in this thread - they've been talking about this unit for years, they *really* need to get one to Dave or Mike for review!

content: Quote from: Mark_O on March 02, 2015, 08:56:09 amNot really surprising, considering that even the roughly $1M LabMaster 10zi 100GHz scope comes with a paltry 1280x768 screen. And that is a scope that can have up to 80 channels.
