content: Looks to be using a UI resamplance of Micsig's other MHO models. (MHO3 & MHO6)So I would guess, you do have statistics and all that jazz.Screen ratio also matches 16:10 (1280x800)

It is like an upgraded STO1000C/E series.

With convenient analysis and viewing functions, it allows for both integrated and individual display, making analysis and positioning more accurate and efficient, turning "finding a needle in a haystack" into a possibility."source:https://www.micsig.com/MHO1/

content: This was just released on youtube:https://youtu.be/MB7G8_siJa8I asked my local distributor about this scope, and he said this model would come to Europe "very soon", but details about date and price were unknown. He thought that this could become a very popular scope if price and performance is ok. Micsig is a bit of a higher risk scope - less volume, less support, less general maturity - compared to Siglent. So, im keeping my eye out for this one, because i like the concept of mobility, proper knobs, and big screen. But im also aware that one of the newer Siglent HD scopes might be a safer choice.

content: Hello,I have had a very good experience with the support from Micsig.When I entered a license for my MHO3, the frequency was set to 0 MHz. As a result, the filters no longer worked.I asked Micsig for help, which they gave me. After a few days they solved the problem and gave me a license for a higher bandwidth.Best regardsegonotto

content: Good to hear they are responsive to online support.What my distributor was talking about is more related to hardware support. Siglent apparently has a support center located in the EU, while Micsig does not (or so i assume). Might make it a bit more time consuming if a device needs repair or service.Anyway,i still like to see reviews and teardowns of this unit. From what i can tell from the short intro video it seems to be quite responsive on the UI.

content: Thanks for the datasheet! Interesting to read some of the specs.My impressions are that it has a lot of nice features, hopefully properly implemented, but it is perhaps lacking a bit on capture performance? Single 1GSa/s ADC and 50.000 waves/s update rate. That makes it perform about half as fast as the old Siglent SDS1x04X-E (dual 1GSa/s ADCs, 120.000waves/s). So maybe that comparison is a bit unfair, the MHO1 is targeted more at field work (hence the battery) where capture performance is perhaps slightly less important. And of course it does have 12bit, bigger screen with touch, so that is a true step up from the Siglent.So yeah... im not sure that with these specs it would replace my SDS1104X-E, but it sure as hell would outperform my Owon HDS2102S in every possible aspect. Well... except for the function generator output.I wonder if Micsig has a function generator integration option, so you can get things like bode plots. The newer siglent HD scopes really do shine in that department it seems.

content: Quote from: S13 on January 17, 2025, 09:10:16 pmI don't know what your Siglent SDS1104X-E actually performs and what is real-world vs specifications.Many vendors tend to spec-race, many of these criteria for sale incentives.I recall Rigol's entry listings DHO800&900 are often listed with 1.000.000 wfps and some buyers take that on face value as the scopes norm, from third-party sale listings that are quite silent about the ltd circumstances some of these specs are achieved under, while in actual use and in "normal auto-memory" (where the specs claim 50k) it seems to peak at around 27 to 28k.. at least the impression I get from Daves video, maybe that value has increased with later fw..https://youtu.be/S8jrpCoZyx8?si=RxRWCflm2w2qeWwB&t=1389There is a notation inserted at 23:53 with a Siglent 1104X-E and 17k wfps as a compare reference' but I don't know how Dave tested it on that model, and if there are model or fw variables that will fluke that number, and if Silent got fixed memory selection or Auto, and to what extent their sequence vs normal operate.There is a lot of wrong info going around.. and certainly also on Micsig.Even a somewhat decent sized salevendor like Batronix.https://www.batronix.com/shop/oscilloscopes/Micsig-STO1104C.html?Will highlight on the older STO-C model.QuoteWhile their own specs just below on the exact same model STO1104C says 80.000 wfms..In practise and while your in auto-memory mode.. STO1104C peaks around 100k (around 98.000 If I recall correct) which certainly wasn't bad for a handheld unit at the time in that pricebracket.So the best thing is usually to either test it yourself, or get someone else that got it, to check specific specifications that fx matters a lot to you.

content: Quote from: DaneLaw on January 27, 2025, 05:34:22 pmYep, done by all every since earliest DSO days.Understand that most DSO's work in 2 triggering modes, Sequential and normal use.Sequential is with minimal blind time and limited to a # of continuous display captures, dependant on DSO settings.Both modes are dependant on settings which are different for every model and brand and the max WFPS spec claimed is always best case.Add in Normal or Single and use of all the settings that provide best WFPS and you have your answer to any DSO's peak ability to capture some event.Preparing a full table to quantify best WFPS settings is a considerable task.......

content: Quote from: nctnico on January 27, 2025, 10:59:57 pmI brought it up because even according to their own metric, it is a step backwards from their older STO series (130.000 waves/sec). I had assumed the MHO1 was supposed to be a step up from that (higher resolution, bigger battery etc, "next gen"), but maybe its not?I agree that waves/sec is not as important as it sounds, probably having good trigger capabilities to detect that once in a lifetime runt pulse or whatever, is more important.But still, i kind of use it to estimate the performance of a scope. Since waves/sec is sort of inversely related to the dead time of the scope (the part where it has to do the processing, measuring, etc), it kind of gives a sense of the processing power. So in that sense it can be helpful. But maybe we need some objective numbers here, and not whatever numbers a marketing department comes up with...

content: Quote from: S13 on January 28, 2025, 10:10:03 amWhy are you comparing it to STO1104C ?STO1104C had only 28MPts of memory, for instance. Claimed Wfms/s could be achieved only in special settings.Also I don't see this scope as a replacement for STO1104C. That would be new versions STO1004 and STO2002.MHO1 , I think, is Micsig reimagining of the scopemeter concept in tablet form factor. Micsig did have (once upon a time) classic scopemeters but they stopped producing them.It seems they are returning that type of product but in tablet form.We will see how well it works.I used both my STO1104C in field, and for years had used original Scopemeter..I must say that while tablet scope is portable and usable, Scopemeter form factor feels more appropriate (for the lack of the better word) for the more "in the field" work.Tablet scopes are more of a scope you can take to different office today. Scopemeter is more of a "take it to see generator in the field".So like with many new products they released in last year or a two, I really don't understand what market they are aimed for...

Tbh, i dont know how long that has been on the market, but since with the MHO1 we are at "GEN 6" i assume it has been out for quite some time now.

I see this as a different segment product, not to be compared to STO range.Everybody seems to think that all scopes should do everything.If this scope has DMM inside it is a "scopemeter" type of product.It is literally new class, in parallel to other types Micsig does.On which different types of priorities would have driven design decisions.For scopemeter, I would optimize for low power consumption, not speed, for instance.

content: Quote from: S13 on February 19, 2025, 09:42:47 pmThx' Certainly gives a good indication of the very similar UI but with some long-awaited added benefits.Seems the bootup time is around 47 sec. to the scope is loaded.. if I recall correctly the older models were also around that... it's mainly Rigols.. that are way past +1 minute on their latest fleet..At least on the sig-gen I got, which is like +65 sec and also seems to be the timeframe on their latest scopes.Not to fond of Micsig's new UI colorscheme with black & cyan highlight but it seems to be quite common acroos their models...I dont know if the user can change it in settings?Personally prefer the older denim-dark blue UI theme, -From the posted billi-video, it seems the UI is holding a huge area of the right-side up for no good' and the waveform starts like 2cm in, same with the bottom with around a cm to the waveform window starts, I get that it's likely intended to display some added text and values but it also makes the waveform area smaller for your precious bits..A shame. as that is one of the things I'm not fond of on Rigol's UI that secondaries, bezels and their corresponding window, constrain so much of the actual waveform area, not least on bench scopes that already have relatively small screens ... Instead, they should maximize the waveform display and ideally provide the option to hide unnecessary info bars & UI elements when not needed. However, this is obviously easier said than done on digital oscilloscopes due to the crucial pixel mapping to their raster grid.// Checked an older vid.. the bootup time on the older models like STOxxxxC/E is around 37sec, though when first arrived, it was faster to boot and down around 30 sec. (if I recall correctly) but apps & data on the scope. like all the office programs, so you can work with the scope-data in various office programs on the scope itself... graphs, arb waveform values etc.. slowed it down a tad, so now it's more like 35 to 37 sec. before the scope aspect are ready, I don't know if its the same on newer models.Bootup timeExamples of Misig's previous UI scheme, but it likely comes down to taste.

content: Thank you for that comparison DaneLaw.To be honest i dont mind the colorscheme, i think it looks ok. But yeah, the large bezels on the side of the graphing area is wasteful.Boot time is not great. If you are out in the field making a quick measurement, waiting for almost a minute is a long time...I still wonder what price range they are targeting for this scope. The reviewer seemed to make a comparison with the Rigol DHO804 and the Siglent SDS804X HD, so maybe it is in that ~€500,- price range?

content: In the video at 29:20 where the reviewer is doing the bandwidth measurement, i noticed that the waveform seems a bit jittery on screen. Even at just 20MHz sine input. I wonder how stable the edge level triggering of the scope is. I know this is something that lower end scopes just suffer from, but it kind of annoys me if a scope cant even show a stable waveform on screen.Could also be a clocking architecture limitation i suppose.

At the beginning MHO68-350 was 5999 € without VAT, then it gradually became more expensive until it now costs 13999 €.At evision, the MHO68-350 costs only €9,518.81 with VAT. They've had this mistake for a long time.With the MHO3, the difference between different bandwidths has changed. A year ago the difference was 1000 € each. Batronix calls for € 2,299 for the MHO3-2504, at Micsig Germany it is € 1,850.00 without VAT.Best regardsegonotto

USA is so entangled with China.. I think Trump is gonna cave in, also in regards to China, and find some middle ground.USA got the same problems like so many countries here in the west, that are killing regional jobs like there are no tomorrow, and outsourcing to the Far East and low wage countries to optimise profit.- it goes without saying that ain't sustainable in the long run.I hedge and speculate in stocks and tend to like voltality, but it ain't the stock market that is setting the pace and create the pressure, but the bond market, and why Trump had to fold, with his "extension to the rest of the world" as foreign players were drastically dumping US bonds, not least Asia that is one of the biggest holders of US bonds.When you're selling state bonds.. You display your faith in the "future" of those state bonds. Are severely diminished, and not the safe haven to store & derisk value..But who wouldn't, with such a display of a one-man-regime, got a mentality like a spoiled, entitled, spiteful child, that has never been told no.Have you tried to ask Saelig..if their orders with Micsig are from past tense, as some companies do make orders before actual delivery but I don't know how Trump tariff are implemented in practice..//It does not look like it (at least for new orders) as Saelig now lists the MHO14-100 price at almost 1600$https://www.saelig.com/product/mho14-100.htm- while a brief frontpage-search on their site. claim 700$ (likely the older price)To put that into perspective..In England it's 707$ in total for a given MHO14-100 (595GBP incl. VAT)Denmark it's 904$ in total MHO14-100 (800€ incl. danish EUVAT)That's quite something... higher prices than even here in Denmark. which is the most expensive country by far in EU with 150% above the EU-average, though the wages is also high..

content: Sure looks nice for a portable scope that is still usable. I actually love the form factor (front BNCs) even though I could have lived without the multimeter part. E.g. I wonder how easy it will be to exchange fuses for the current ranges. Also the technical specs look OK for this price range.It would have been nice if they had at least kept the automatic probe detection, though. I also can't shake the feeling that too much space on the screen is used for touch controls and it would have been possible to reduce that a bit to have more space for the signals. What also puzzles me is that the intensity grading on the available screenshots doesn't really look state of the art.Anyway, I'm looking forward for a first review, Hopefully in the next weeks.

content: Micsig's Intensity grading is usually pretty good, though this ain't from MHO1, but an older STO1104C and vids from a handful of years back with a lightsensor / lazing diode, but it still gives an idea of Micsig's 256-levels of intensity grading both in native ch. colors, and heat mapping, as it's likely the same look-up table that Micsig is still using, which back then was the BGYOR wavelength color-toning spectrum for the CCT.I think it's pretty good, and I was quite impressed with their 256-levels of grading and their LUT for temp-visualization.https://tinyurl.com/386ss23wMaybe it's been changed with updates over the years, and on newer models, -but it gives an idea of the Correlated Color Temperature template Micisig was using back then.Waveform capture rate in standard auto-memory peaks around 100,000 wfms/s on that older STO-1104C battery model, while newer models and certainly also MHO3 and MHO6 are faster, but it could look like this coming "MHO1" is spec'ed a tad lower, at around 50.000 (normal auto) Its likely better in practise at ideal scales, but like always it varies drastically across settings & time standards. (I'm not referring to any post-sequence / segm. aspects, just normal use)I do like Micsig's temperature grading profile.

content: Wasn't this already posted in #26?Looking at the datasheet, there is obviously only one ADC (as in the STO1000). So the sample rate and memory is split when using more than one channel. Also, the timebase accuracy is only specified as 20ppm which is slightly underwhelming nowadays. There's also no channel-to-channel trigger (as in the STO1000). I think it's slightly sad that the more advanced probe connectors of the STO1000 are gone. I'm not sure if there were ever active probes using the serial connectors, but this also means that there's no automatic probe detection.Anyway, I guess for a tiny mobile scope, these things don't really matter and it still looks like a solid little scope from what I can tell.

That ain't something I miss on a scope in this price bracket, where x10 is the norm, and I don't think Micsig even got other attenuation standards for their common passive vprobes..

content: I have to agree with DaneLaw on this one. The examples provided by him show that Micsig does indeed provide samples for review and marketing purposes.Also they do run a website, have a youtube channel and market through resellers and distributors.Now obviously Micsig isnt anywhere near Siglent in terms of size, support and marketing, at least here in Europe from what i can tell.Also it is important to remember that Chinese companies do work differently from what "we" are used to. It does feel foreign if you ask me. And indeed whatsapp is a common way for the Chinese to do business. For them it is just a highly efficient way to communicate with western clients. Again, i agree with DaneLaw here.

Besides, it's somewhat concerning that manual and data sheet say that the serial decoders/triggers are "optional" (even though Batronix says that they are included). I faintly recall that the first Micsigs also came without the decoders but when you asked their support, you still got them for free. Still, a weird approach. I surely can live without the 50Ohm inputs on such a small, entry level scope and the memory should be also sufficient, but it could have been closer to the SDS800X regarding the technical data and features. I'd instantly sacrifice the multimeter feature and battery for that.I still like the screen size/resolution and form factor, though

I know it's a bit exotic but my siglent supports arbitrary length. Signal decoding works well even so, and the protocol trigger feature is really cool (not had such a feature before).Was reminded while using my siglent that no matter how good a touch interface is it doesn't beat full manual controls in terms of intuition. On the other hand, the touch screen is really useful for zooming in and out and moving a signal around, and the micsig does have manual controls for most things.The USB C charging is really nice, cant see me using the supplied transformer at all.

If i was in a lab with usb power everywhere, i wouldnt bother with the battery at all to be honest... I'd get a scope that runs on usb-c exclusively.Is 2 hours enough to measure signals in the field? Eh... maybe...? For some simple captures perhaps? But i'd say it depends.If you are doing some in depth debugging and analysis, 2 hours is very short. I mean it isnt a device that you just quickly power on within seconds to measure a voltage like a multimeter. A scope needs boot time, setup, wiring etc. Before you start to actually measure, you're already 15 minutes in. And then there is waiting for the event you are trying to capture. And afterwards there is analysis, saving the results etc. Maybe you need to make some on site changes to the thing you are measuring. And then measure the changes on the scope. 2 hours wouldn't cut it for me to be honest.An usb power bank might be a solution of course.Quote from: DaneLaw on June 16, 2025, 03:47:33 pmYes this is deceptive if you ask me. Market it with what seems double the size battery of the previous gen (but really isnt, its the same amount of Wh's) and to top it off you only get half of the run time of the previous gen...

content: Quote from: Wirehead on June 21, 2025, 04:35:51 pmNo. Min would show the lowest level of the signal (or max the highest).Offset is mainly used when the zero line is not on the screen, like when you have a 20 V signal and you check it with 1 V/div because you want to see a lot details around the 20 V area so you move the zero line for example 18 divs or 20 divs down.Then this will show a line somewhere on the screen but you wouldn't immediately see the value of it so usually the scopes would display 1 V/div and -18V for example. At least the DSOs I have been working with so far (Tektronix and LeCroy at my former job and my old Fluke at home, even my Rigol does it).Here I can't see the offset displayed.Maybe it's just something I am used to and to be honest it's not absolutely necessary since I can still enable measurements as you already mentioned. For me it's just strange that this information is missing on the screen. I'm simply used to keeping an eye on that value.

content: Many scopes do not show channel vertical offset on the screen directly because it takes screen spaces and offset is a secondary priority (number of divisions, V/div, grid labels and GND symbol implies offset). Turning channel offset may bring up numerical offset value in some scopes.Micsig is sparse w.r.t. grid labels in previous models, it's a GUI design decision.

It's running constantly, and the back is getting warm.Are you able to use standard multimeter probes? The ones that came with my unit have a retractable shroud, and standard probes that don't have a retractable shroud don't fit.What type of multimeter fuse do you have?

Shroud length of typical 4mm probes is ~22mm, normal length socket is ~24-26mm (shorter sockets exists). MHO1 likely uses single PCB construction, so 4mm sockets would be a very tight fit. Sockets on the side would not be space limited.Fuse situation requires more attention if automotive fuse is used.

content: My observations on the fuse situation:The fuse part number specified in the User Manual (both English and Chinese versions) is 0216010.MXP which appears to be a Littelfuse ceramic part with a 10A @ 250V rating. The fuse holder is also shown with a small indentation in the center of the holder to allow a screwdriver to pry it out for changing. The 10A symbol molded into the holder is centered as well.All variants of the MHO1 that I've seen in the wild at this point (my own, Sorama's unit, the ones shown in videos on bilibili, the one Dave saw at Micsig's Electronex 2025 booth) use a different fuse holder with the fuse symbol and indentation offset to the left and covering presumably an automotive mini-fuse holder. Pictures of my unit and spare fuse are linked below.My assumption is that any MHO1 units with such a mini-fuse should only be used to measure currents in low-voltage circuits up to around 32V max.

I purchased and am usingthis Cudy WU650for its compactness.I asked Micsig for a list of supported chipsets / drivers, and the person I spoke with couldn't provide one.If the chipset is supported, the USB dongle can be hotplugged during operation and WiFi will be made available in the system.Other chipsets in the same family may not be supported. I tried the TP-Link WiFI/BT combo device (Archer T2UB Nano) and it definitely does not work. Linux driver support for these combo devices is limited and would require special configurations.I found thisUSB Hubto fit nicely on the MHO1 in case anyone is trying to use multiple USB devices.

Don't you think that this will ignite an electric arc in the fuse that won't stop burning as the fuse is only rated for 58 V? There is no sand to kill the arc. That means potential danger with burning device, overheating probes, etc.If you specify Cat I / 300 V the device has to comply with it. Simple as that.

content: The voltage rating of a fuse determines its ability to suppress the internal arcing that occurs after its link melts and an arc is produced. If a fuse is used with a voltage rating lower than the circuit voltage, arc suppression will be impaired and, under some overcurrent conditions, the fuse may not clear the overcurrent safely.

content: Quote from: Sorama on July 14, 2025, 03:45:48 pmI'll save you the trouble. They will potentially release a new design variant at some point in the future with an HBC fuse similar to the one that's shown in the user manual. They have intentions to qualify this device for IEC compliance, but obviously the current revision may not suffice.And like you say, maybe it doesn't matter for most people working with low voltage circuits (actually 58V is already much better than typical 32V rated automotive fuses). Problem is, it's clearly specified in the manual that a sand filled ceramic HBC fuse is used for the 10A range, so anyone making their purchase decision based off that information would have been deceived regardless of whether the mini fuse meets their use case or not.

See picture below, that's not what's used on mine.Maybe they originally planned to use the Littelfuse 0216010.MXP which is a Fast-Acting, ceramic body, sand filled cartridge fuse but then they might have selected something different. Anyway, at least in my scope there is this "definitely-no-250v-fuse".And - besides - even the Littelfuse 0216010.MXP would be a hell of a lot more suitable it would still be the wrong choice for a mesuring device rated Cat I / 300 V.

It simply doesn't display the playback options as shown in the manual and nearly 99.99999 % (very rough estimate) of operations I'm doing on the scope will reset the captured frames back to 0. Nice.

content: Quote from: msnremea on July 20, 2025, 02:38:25 pmFor those of you who wonder about segmented storage:1. Make sure your trigger is setup properly so that you are actually capturing the thing that you want to look at. For both Single Shot and Segmented mode, the MHO1 will always function in Normal trigger mode, so you dont need to switch from Auto trigger mode to Normal trigger mode.2. Go to menu: "Sample" -> "Segmented Storage" -> and here you check "Segmented Storage" to activate it. Also select the Number of Segments to your liking.Note: the record length for each segment is always the width of the screen, and cant be adjusted as far as i'm aware of.3. Now press "Single SEQ" button on keypad or screen and watch as the Segmented memory fills up.4. When the segments are all recorded, you should get a menu pop up that allows you to display the segments individuallyNote : if you dont want to wait for all of the segments to record, you can always prematurely end the capturing process by pressing the "Run/Stop" button. You will then only see the segments captured up to that point.5. You can overlay all of the segments at once with the "Fit" option. This is actually a nice feature!One kind of anoying thing is that the Popup menu goes away if you try to access other menu's. This is no problem. You can always access other menu's, add measurements, use the Zoom function, etc, and the recorded segments should stay intact. Then to restore the Popup menu for browsing through the segments, you access the lower menu (swipe up from below, or press the physical "Menu" button right underneath "Cursor 2" button) and there you press "SG View" on the screen. This button is kind of difficult to find, so i assume people struggle with this a lot. Micsig should really redesign that popup menu so that it integrates better with the rest of the UI.Hope this helps!

Its a huuuuge leap forward from the Owon HDS2102S that i previously had for field work.ok this thing is in another class of course, but still...In my opinion there are a couple of things that Micsig actually does better than some of the competitors, like the dual rotary cursor control, the consistent snappy speed of the UI (no slow downs when using math, measurements etc), the additional side apps, fully adjustable lo and high pass channel bandwidth, Y-grid scale labels (why dont all scopes have this!!?), etc. If you get used to the UI you can work pretty efficiently, because there are shortcuts to menus everywhere. And they really have integrated touch screen control properly, its not just an afterthought.Now on the flipside, the menu structure is a bit chaotic if you ask me. It could be a bit more "professionally" styled or something. Other areas of improvement would be the FFT function, it really is too basic. Battery life is also not according to spec. I measured only about 2:15 of usage on a full battery, just like others have here on the forum. So the -N version isnt different in that regard.But to be honest all of that doesn't bother me too much. The one thing that i think makes the Micsig fall a bit behind the competition, is the waveform update rate. The manual specifies up to 50k/sec. Yeah, that would only be in segmented mode, but they don't tell you that. In normal continuous mode you are not getting anywhere near that 50k/s. The limitation is, i think, that the Micsig does not overlap multiple waveforms before they are presented on the screen. So you get a waveform update rate that is linked to the screen update rate. Each screen update only contains a single waveform. Granted, the screen update rate is really snappy as i mentioned earlier, but that limits the rate to ~50 to 100 waves /sec. That means you also don't get those nicely intensity graded overlapping waveforms that even the cheaper Siglents (like the old SDS1000X-E) have. And finding those rare signal glitches on persistence mode might take you a long long time...But hey i get that there are compromises with a battery powered scope, so im not complaining. For the price i think this is a pretty competitive scope!Now to go and find a decent carrying case...

content: Quote from: S13 on September 05, 2025, 05:24:47 pmThis can't be true if you look at the modulation examples shown above. And no scope can actually update an LCD screen faster than what the LCD screen is able to (which almost always is 60Hz for scopes).But every somewhat serious scope in the last 30 years or so did some kind of "digital phosphor simulation" by using tens, hundreds or thousands of measurement to calculate one frame to be displayed.But usually that doesn't work in single shot mode and the actual capture rate depends on different settings as memory depth etc.I.e. the maximum waveforms per seconds can usually only be reached in very specific settings. E.g. even scopes with 250k waveforms/s can't nearly reach this capture rate if you're using the maximum memory depth.Also. e.g. if you're capturing a 100Hz signal, there are only 100 waveforms to be captured per second. I.e. you're stuck with 100 waveforms/s then unless the scopes pulls of some tricks.

content: Quote from: 0xdeadbeef on September 05, 2025, 10:56:31 pmYeah im not sure if im doing something wrong here. I was surprised as well?Im not talking slow signals. I was trying to capture an eye pattern for a 40MHz prbs signal. So we are talking ns/div ranges here, and very limited scope memory. I'll do a comparison later in the day between a SDS1000X-E, SDS1000-HD and the the MHO14-200N and show the differences.

content: Quote from: S13 on September 05, 2025, 05:24:47 pmThis is weird. I have TO1104 which has it, and it's like a 10 years older model. Are you sure you didn't activate "speed mode" when it increases update mode by disabling intensity grade and using less acquisition memory? (from bottom menu on my scope). Or may be intensity grading is disabled?I don't use intensity grade on my scope. It looks fancy, but it has a performance penalty.

content: I don't see anything like this mentioned in the manual (i.e. neither "grading" nor "speed mode" nor "intensity" can be found). BTW: according to the manual, there is also no interpolation selection (sinc/linear).But there is a "color temperature mode" which should replace the normal intensity grading with different colors. So, this could be used to check if there is grading at all (without using a persist mode or so).

content: There is no speed mode or ability to enable intensity grading on the MHO14.Anyway, i have it figured out, sort of...I had to omit the SDS1000-HD comparison, because it died on me while testing. I think its internal powersupply just went pooof!So i can only compare with my old SDS1000X-E. What im showing is a 40Mbps PRBS signal with some noise superimposed on it.So this was the original problem i had with the MHO1 where it would only show one waveform each screen update:Note the phone i was taking this picture with actually shows a couple of waveforms, but that is due to the slow shutter time i suppose. The screenshot is what you actually see.The siglent is doing much better by default. Nice waveform update rate with many overlapping traces and intensity grading:Well, turns out the MHO1 can also do it, however, you have to enable Segmented Storage!In fact, the depth of the storage also influences the amount of traces drawn each screen update. But you just let it run continuously, without using the "Single SEQ" button.Lowering the intensity also shows the intensity grading feature:And yes, color grading also works in this mode!Persistance also works nicely in this mode, and again highlights the intensity grading. Nice!Ok, so problem solved i guess! Its just a bit weird to have these 2 different sampling modes, and having to enable Segmented Storages to get what is actually the normal sampling mode on other scopes. But hey, at least it is in there!

content: Had a chance to look at Micsig MHO1-200N, initial impressions:Nice form factor, integrated legs fold in flush with magnets.GUI is nice and responsive, both touch and buttons work well.Scope functions work with no major bugs.Fan is small & noisy (either ON or OFF, mostly ON if scope is running).FW bugs:trigger selection up/down buttons sometimes change AUTO/NORMAL mode, i.e. if trigger is AUTO, changing trigger source leads to NORMAL (or vice versa). Changing trigger source from menu with touchscreen does not have this issue. Unclear when/how, can reproduce often.On CH1 pressing "50% trigger" level showed 1V offset while for CH2-4 it showed 0V with no signal. Unclear when/how, can't reproduce again.Few times screen and buttons became unresponsive - restarted scope app to fix it.Feature request:Add a way to force trigger with buttons/touchscreen as currently there is no way to force trigger in normal trigger mode. Manual mentions that trigger is forced in auto mode, but that is "automatic force" and not "manual force". Previous Micsig's had dedicated force button - maybe use push function of time knob for this function.Add indication that scope is in roll mode, currently it is not indicated. In "roll" mode trigger information box in top left becomes blank, so there is space to add status text there.

content: I would guess it has the same 256 levels of intensity grading as the older ones.I do like the look-up table/LUT Micsig is using, and I reckon it's the same, on these newer models, as previous..https://tinyurl.com/54armcjfIt seems to save some EXIF metadata for the edit programs in the scope.https://tinyurl.com/29c66774On the older budget-entry series, the waveform wfms/s was pretty fast in normal real-time acquisition mode.If I put it into auto-memory, where it is most of the time, it peaks at just under 100,000 wfps (around 97k), obviously under ideal timebase.Which aint bad for normal real-time acquisition-mode on a mobile scope back in 2018, but Micsig labelled it as up to 80k and why their claim of fx 50k on MHO1 could perhaps be downplayed a bit.But looks like they have sacked aux-out on the MHO1 series.

content: Quote from: DaneLaw on September 06, 2025, 05:39:29 pmYes the MHO1 has no aux, so no way to check the speed sadly. Would have been nice to see the difference between the modes and chosen segment length.So, your older Micsig is pretty dang fast! Even the Siglent SDS1000X-HD doesnt seem to go much further than 29k/sec in normal continuous acquisition mode. And the older SDS1000X-E is slightly below that. So 97k/sec is nothing to scoff at!The MHO1 can do about 50k/sec in segmented sequence mode. At least that you can sort of check by how fast the 50.000 records fill up (takes about 1 second).Oh a feature request of my own:Make Intensity adjustment available on one of the rotary knobs. I think knob 1 is only used within the menus, so maybe when viewing only the wave screen use that knob for intensity control. Right now you really have to dig through the menus to make an adjustment.

content: Quote from: 0xdeadbeef on September 06, 2025, 10:14:03 pmYes you are right!And it worksIve tried many different settings to see how the capture rate changes.It is a complex interaction between the selected timescale and the selected number of segments.At peak, when running in true segmented single capture mode, the segmented memory works up to 167K waves/sec, for a maximum of 10.000 segments. Pretty nice!When running in continuous non-segmented mode, you basically get a pretty consistent 36.8 waves/sec over pretty much the entire timescale up to 500us/div. Beyond that the waves/sec starts to drop as expected. In this mode the FPS of the display is equal to the waves/sec. In other words, you always seem to get 1 wave for each screen update. 36.8waves/sec is quite poor if you ask me, but if you favor consistent high display FPS, this is the way to go.When running in continuous segmented mode, you can get a lot more waves/sec, but there is a bit of a tradeoff with the FPS on the screen. Especially around the 100ns-100us/div the frame rate drops significantly. But you can get up to 9.9K waves/sec on the 2ns/div timescale and 1000 segments. I'd say that is pretty ok.

At least i assume they have some kind of processor core running in the Zync SoC too? And there is even a third tiny CKS micro for what i assume is for user interface / front panel processing.Now what would be the purpose of that tiny switch??

content: Thx for the great pictures Wirehead.Have they removed the speaker altogether?Looks like Micsig went away from metalthreaded insert and relies on selftappers on current models.ON the older model, they relied on a shutload of threaded inserts, something like two dozenMade it relative easy to use these molded metal-inserts as a makeshift non-standard VESA-like-mount, by just using some longer hex-screwsThough selftappers will likely also work okay as long as they align with the previous groove, it should be strong enough to hold, not that heavy a unit..From Mikes YT video (STO1104C)Was my crude plan on the older model, just exchange a few of the hex screews with ones that were a tad longer to lock it to the stand, perhaps with a small spacer for air.Simply fit it on one of these quite beefy 2kg alustand with an upper grip, and then I could take it around & place it in the exact orientation I preferred,- though in practise it did not make much sense for my use cases, with a Tek2-like stand approach.

That Tiny CKS micro is indeed running frontpanel I/O. It's well built tbh. The DMM is a handy extra. Not the best in terms of input design, but for low voltage stuff / diode measurement / continuity / ... - it works a treat.On the cooling: i wish they had used maybe a more dense fin design. The fan seems to be PWM controllable, it would have cut back the noise substantially.Quote from: DaneLaw on September 09, 2025, 12:07:02 amSpeaker is in the backplate and connects to the main board by pogo pins, same for the fan - so we still have a proper speaker _with_ a 3W audio ampIt's all still threaded inserts - none of that selftap rubbish

NORMAL/AUTO (when set on the right) is kept when trigger channel is changed. NORMAL/AUTO (when set on the top) isnot keptwhen trigger channel is changed.Still no way to force NORMAL trigger.I have to say that legs on MHO1 scope are very nice and practical (easy to extend or retract).
