content: FOREWORD: I have just received my (second) Migsig STO1104C and feel very comfortable with it. Of course, there are more questions than answers, especially at the beginning. I therefore think it would be good, especially for beginners or those interested, to put together a few pieces of information that were not entirely clear to me in my initial research and that are scattered over many individual threads here, some of which are even off-topic.Although some operating peculiarities are additionally solved differently with the "button variants" (STO), many general questions about software and operation (also the operating system interface apart from the actual oscilloscope) and solutions should concern the entire Migsig scope family. Some things seem abnormal, but are not.I would try to collect by edit the questions and answers bundled in the first post and keep them as up to date as possible and also collect links to other migsic-scope related topics there. I know something like this from other forums and it has proven itself and saves newcomers from having to read through a long thread with hundreds of posts.If something like that is rather undesirable here, please just let me know. Maybe there is already something like this somewhere else and I have just overlooked it so far.Here are my initial questions/statements to the Migsic community, which I would like to ask the Migsic community to answer and confirm or object to.Hardware---H1: Contrary to what portability might suggest, the Scope is of course grounded as long as it is powered by the AC adapter ...H2: The probes supplied have a 1:10 division ratio and cannot be switched to 1:1... I miss that!H3: It seems to make sense not to "shoot down" the scope by a long keystroke, but to switch it off by a short keystroke and popup menu.Android system---A1: Updates offered should be treated with caution.Never change a running system...A2: The WLAN symbol on the desktop is often displayed with an exclamation mark (disturbed Internet connection), but everything apparently works anyway.A3: I can set an IPv4 address in the network for the LAN connection, but I miss the settings for a WLAN connection. No way?A4: I am still looking for a way to actively push screenshots and data away from the scope to a network storage instead of getting them from the computer via FTP server.A5: I miss a PDF reader. Is the WPS Office to install the only way? The scope's manual is in pdf and can be displayed on scope, by what means?A6: Installing my own apps would be nice, but the system won't allow it (for now and also reasonably). Has anyone already managed to do this? Could Migsig be asked to add a freely available app to the store? (a file manager with ftp support would solve my problem A4, ...).Scope---S1: (STO) There is a back button to exit a channel menu without having to turn off the channel.)Tapping on somewhere else on the screen works just as for the non-STO devices, thx FungusS2: (STO) There are buttons to move the cursors, you just have to activate them with  first.The buttons in the left lower corner are the only way for the non-STO. I had to read the manual again and again to find that, after fiddling moving the cursor with fingers ...Other useful threads in this forum:---Review and discussion regarding the (knobless) TO1104Noise on open inputs (without probe)Feedback on Micsig scopes("should I buy it or not") - and have a look atthis thread, too Migsigposted some videos about their scopes hereCreate (and use) own apps on the Micsigs? If using Linux, maybe you shouldkeep an eye on that...(tbc)any hints and questions are welcome, thx!!!

I dunno. It's not exactly the world's best office suite.Ihaveused the web browser occasionally to bring up datasheets and stuff. It can also play media files and view youtube but the sound isn't very good.Mostly I use it as an oscilloscope. The only app I really use a lot is the ftp server for grabbing screenshots from my PC.I'd like to use my HP15C calculator app on it but as you say, we don't have permission to install .mkv files even though the file system looks for them and lists them under the apps category.I don't remember but I think PDF files open just by clicking on them.

content: Above 3 hardware question.H1, Yes.H2, We found fixed 10:1 probe quality is better. and many suppliers use same way. you can buy one more probe. buying more tool, earning more money.H3, many android device shut down by pop up menu. so we are same.Using the scope is simple like to use a cell phone.I hope i can become a member of this scope community.

content: Quote from: Micsig_support on July 08, 2021, 06:33:32 amMeanwhile, I found this more often and there are clear advantages of pure 10:1 probes.Nevertheless: my 10 years old (absolutely) beginners scope have two switchable ones, and for low frequency things I found it useful to take those probes for a universal pickup and put the signal to more than one device at the same time. They managed to built the probe up to 100 MHz (in 10:1, 1:1 only for some MHz). I will use one of them with the MicSig in future. Everything's fine ...QuoteAlmost all do so. But in scope mode, there's no Android anymore. The STOs can be operated only by means of the knobs, why not switch 'em off this way? You put the "shoot off" feature on a (rather short) long power button pressure. Most PCs you can "kill" by a 4 seconds power button pressure, most Android devices can be hard resetted by a 10s pressure or so.As long as it will cause no problems, the long power shoot off will be a workaround, but as I understood (saving scope's settings and so on) it's not healthy to do so.Take it as a suggestion: Make the hardware shoot off longer (>4s) and take a 1 s button press for a command AND ack to make a normal shutdown.This leads to another point: My smartphone is switched off once a month, maybe, but I use the power button to put it in STANDBY, from which it comes up in half a second. Comparing to other scopes, they all have no standby feature and boot times of 1 min or more. But here, we may have a chance to get a real standby, with switched off display and stopped fan and a fast coming up? As far as I understood, when pressing the home button, leading to the android desktop, the scope's hardware stay powered (only wfm aquisition is stopped, thus the scope app is back in a second). This will not work for a standby here, as I think the scope's hardware has no sleep mode, but then shut down the scope app and put the rest of the system to a kind of sleep condition (just as a S3 on PC), so the system is back in 1 second and users have to wait only for the scope app restart and hardware initialization, which seems do be done in seconds (like my old UNI-T, which has a cold boot time of 4 seconds).If not for my, maybe for further scopes?QuoteFor all who are familiar to use a (android) phone.QuoteI would extremely welcome your comments on all the questions and points here and wish you to read and consider everything.And yeah, this could be the thread to communicate wishes and bugs, too.So, what do MicSig think about an automated data synchronisation in background to a ftp server? (see my point A4).

content: Quote from: Pfriemler on July 08, 2021, 09:06:00 amYes. It's a good decision. I'm much happier with a higher quality 10x probe than a cheap switchable probe.The fixed 10x probes are also much safer for the oscilloscope in the hands of newbies.

content: Quote from: Micsig_support on July 16, 2021, 08:34:30 amYou mean me?May I remember that - maybe, if not a hardware issue, think my old device is still on the way back home - this update made my device unusable?edit: OK, installing the SysUpdate-App will not harm the device, but I did use this app and made the offered upgrade before I started to work with the scope.And before that, a "what's new" or changelog would be nice to read... In principle, I would be quite willing to do updates and tests.Quotenohohooo, not mine- but yeah, in this way. There is no need to invent the wheel twice - there are enough Android apps that can monitor one directory in the background and synchronise it with another.Code:Do you when you save the data in oscilloscope, then the data will be uploaded to your PC mean time?Something like that - not to a PC, but any FTP/WebDAV/Samba. It's not that necessary, since I found a workaround with my smartphone - using a file manager bookmark, connecting with the FTP Server on the MicSig and my NAS and copy all (new) files from MicSig to NAS allows me to finish work and switch the scope off without the need to run the PC. Even renaming screenshots is easy this way (for additional infos, it happened to me that I could not recognize the reason why I did 'em). Better: a prompt for some text before saving the pic. But I didn't found that function yet, in any cam or screenshot app.

Here's a photograph of the screen:The camera makes it look worse, but even on a screen capture you can see the problem clearly - many of the horizontal and vertical lines are hard to see because of the antialiasing combined with red color:My suggestion is to draw the text in white (which is much more legible) and draw a border around it in the color of the math channel:(compare the white text with the red text on the left - white ismuchmore legible)nb. 'White text with colored border' also matches the scheme used by the channel menus:

content: Suggestion 2: Add 'statistics' mode:Some measurements are very hard to make, eg. noise measurements, because the values on screen are constantly changing.With statistics mode the values on screen show the average of all readings taken. This number will stabilize over time and give good values.My suggestion is to add a button on screen to turn statistics on/off:When statistics are on you just accumulate the values of all readings then display that sum divided by the number of readings. Easy!

content: Suggestion #4: "AC RMS" measurement (RMS of signal with DC offset removed).If I have a 1.5V signal with noise then I have no way to measure that noise. Eg in this image the "RMS" value shows 1.488 volts - not what I want. PK-PK is 180mV - not what I want either. I want the RMS ofjust that componentof the signal.Suggestion: Add a measurement that shows RMS of (x – mean(x))On other oscilloscopes this is called "Standard deviation" mode, eg. on R&S:

content: Suggestion #5: Show peaks on FFT measurementsWhen I use FFT mode I have to use the cursors to find the frequencies of the peaks. This works but it's a lot of effort because the peaks move with the input signal and I have to constantly move the cursors to find the new values.Suggestion: Label the highest peak on the FFT to show the frequency/dB value.You could add a button to enable/disable the label but I'm sure I'd leave it on 100% of the time.Much better would be to show a table of the highest peaks like some other oscilloscopes do:Even a table with only the three or four highest peaks would be very useful because it lets you easily see if they are harmonics or not.Maybe the table could be switched on/off using the "FFT labels" button.

content: Suggestion #6: Be able to lock the vertical position of channels.When working with measurement cursors it’s very easy to accidentally move the channel traces by mistake – very annoying!Suggestion: Add a "lock" button to the channel popup which locks the vertical position of the traces (only on the touch screen - the vertical control knob still works).You will need an indicator on screen to show that the traces are locked (eg. at top-right). Touching the indicator could unlock the traces, making it easy for people to get out of trouble if they locked them and didn't know how to unlock them. You could even rapidly flash the 'locked' indicator whenever a user touches a trace to draw their attention to it and stop them from panicking and thinking something is broken.

content: Extra post for discussion:My feature requests are:1) Better text legibility2) Statistics mode3) Combine duty cycle into a single value4) AC RMS5) FFT improvements6) More info in CSV files7) Lock tracesIn terms of priority, I think number (2) is the feature most people around here think is "missing" on Micsigs, eg. it came upheretoday. It's also very easy to implement.After that, (4) and (5) are what would really raise the profile of the 'scope in these forums. I think I can say that many people here believe that (4) is essential in a scope.(3) Seems trivial at first but if you implement (4) then you might needtwomore items in the measurement menu (AC RMS and AC CRMS) and there's only one space at the moment. Combining both pulse width measurements into a single item gives you an extra item.(7) Is annoying when you're trying to align cursors with the trace and you accidentally move the trace then have to go back and align the cursors again.

content: Great work, good suggestions. I subscribe to all of them - also the comments in the last post. (In fact, even now I miss more features (compared to other scopes) I thought.)1) bad red-on-black contrast ist even more difficult with the screen protector on. Meanwhile, I had a 3rd MicSig here for some hours (.. not my fault ). My old UNI-T has that red in Math, too, barely readable. Please, do something!2) yes!3) would be the first measurement with two values, but in fact it's only one with two different units. What's the use of separate these two values at all?4) missed when checking a power supply, workaround with a second channel and AC coupling. Does not work when DC level changes. So yes, please!5) yes, yes, and yes.6) CSV not missed yet, but a really easy and nice to have.7) Fungus, the screen lock is your 7th suggestion ... remember theQuote from: Pfriemler on July 01, 2021, 08:03:00 pm... or move a channel ... :-)Relating to my point A6 and to Fungus question inQuote from: Fungus on July 16, 2021, 12:36:36 pmReally "own"? i.e. 100% self-written&compiled or rather 3rd party apps? two things:a) some other apps may affect/disturb the scope app in a undefined way with background activitiesb) rights management/licensing: As Fungus said, avoiding the Google app store is a probably good idea. Some apps rely on licensing checks via Google Play store and will not work without access. But there are tons of fine, small and really free apps at the F-Droid market, avoiding strange or intransparent background activities.c) The Amazon firesticks had the "sideload" way to install non-market apps. The Micsigs allow to install apps from USB devices, too. But it looks like they are accepting only "signed" apps. Will Migsic open this?d) for me, there's no need to install ANY 3rd party app. Only a few that will do a missing job (like file synchronizing) or better (PDF reader, calculator, electronics tool) will be ok. I think, of all thousands of available apps a selection of maybe two dozens will do, just put them to the Micsig app market - the permission of the authors to do so is maybe easy to get especially for the F-Droid ones.

content: Question: What is wrong here?As I said initially, my actual MicSig is the second due to the fact that the first one was instable and freezed often. In comparision with the mentioned #3 I confirmed that my #2 has a strange bootup delay. The first did start fast like the #3rd. So why there's that annoying delay?Times are taken from a bootup video, in seconds (I did this several times, but the results are almost the same):+8 "MicSig" changes to animated logo+21 #3 Android desktop appears+23 #2 Android desktop appears+27 #3 0 Smart Oscilloscope starts+31 #3 +4 relay klicks+34 #3 +7 Scope is running <--- 10 seconds more compared to a Siglent SDS1104X-E+41 #2 0 Smart Oscilloscope starts+45 #2 +4 relay klicks+48 #2 +7 Scope is running <--- 10 seconds less compared to a RIGOL MSO5xxxxBoth scopes start with (nearly) the same speed to the desktop. The #3 scope app auto start is 4 seconds after the desktop, 34 seconds from button to work. But my #2 scope app autostart is delayed by additional 14 seconds. WiFi on/off does not change this. Service desk on Batronix had no idea, too.@MicSig: Was is my scope waiting for at start?

content: Interesting thing is that you can unlock STO1104C to STO1104E quite easily by usingEFT ProandSamsung ODIN3tool. At first you must dump oscilloscope ROM to file. Then split ROM to file system Folders and bootloader file, cut spare space and then modify files responsible for S/N number and model parameters setting. Then you must load back to oscilloscope part of memory with modified model parameters. You can also probably able to add label function, segmented memory option from STO2000 series models, but I never tried this. So I think it does not make sense to pay more for STO1104E model. HW in model C and E is identical. Motherboards in both are the same STO1000_V5X_MB. RAM Memory is 8GB and FPGA RAM is 1GB, so no bad at all. Of course STO2000 HW is different. I think there will be somebody who will make complex tool for hacking/unlocking micsig STO1000 series features similary as with Siglent oscilloscopes.

Siglent is doing it very successfully here, Micsig needs to do the same, not only to fix the small issues that are keeping people from buying Micsigs but also to gain loyal fans - who doesn't want to wake up in the morning and find their oscilloscope improved since yesterday? The word of mouth (and youtube videos) generated would gain Micsig a lot of sales.I'm a programmer myself and I don't think any of my suggestions are a lot of work compared to all the work that's already been done on the firmware (which is very well designed and polished - there's obviously some real programming talent at Micsig).

Sure there is always room for improvement but in the end the MicSig scopes work as promised. Would you give away your software for free? If you want the features from the newer devices in a few years, then buy a new device.

content: I have a small insight into Chinese designed and produced products. From my experience, the products are developed to the point of providing the desired functionality and a decision is made to release the product to market to recover the financial investment in it. If the product has any significant bugs in its firmware, these are often addressed with a firmware release, though some companies fail to do this. The company desires recovery of investment as its first and highest priority… “sell product” becomes their focus and if the product is any good, it will sell to markets across the World. Minor bugs may still exist in the product but it is not uncommon for these to remain unresolved for a significant period of time, or even forever. Once the product has been released the associated design team often move on to a new project as their work is considered ‘done’. Firmware development is not a free activity so the company has to consider whether further development work on a product will deliver increased sales or just make the product better for current users. Sadly the maths may show that the firmware development hours are better spent on a new product that the design team have moved onto. It is not unknown for a Chinese manufacturer to respond to a bug complaint with “we will fix that in the next generation of product”. They are not trying to be unkind to current owners of their equipment, it is just the business decision to maintain new product development and associated profit. Some companies invest in a firmware and software development team that is large enough to develop firmware updates for current products as well as create firmware for new products that are under development. Those ‘legacy firmware’ staff have to be paid though so the return on that investment has to make financial sense to the companies management.I know nothing of Micsig as a company but we need to consider how much resource they can afford to invest in a product that already delivers on its promises and sells well. “Nice to have” functions may be very important to some users but may not have significant effect on the sales of product in the marketplace. I own the ATO1102 and I find it to be a well sorted compact tablet DSO. Micsig may well be developing the next generation of tablet DSO and their firmware developers may be fully committed to that project. Such a firmware project will likely take priority over firmware updates for a product that already meets its specification and sells well.I obviously hope that Micsig will release firmware with additional features or improvements, but I do understand if they choose not to. It is not personal, just business after all. I am very pleased to own their ATO1102 and what it offers me in terms of portability and ease of use

When I bought my TO1104 they where very clear about what worked and which features they still planned to add. In addition to that what they claimed was finished was finished. IIRC I have not been able to find one single bug despite thourough testing. Later on MicSig did add the features which where promised and they also work as advertised. IOW: be careful with generalisations like you wrote above. They aren't always true!

I have no experience of this but your comments regarding firmware/software development further support the statements I made about a manufacturer needing to balance the cost of ongoing development against increased sales and resultant profitFraser

I'm hoping that (unlike many Chinese companies) Micsig sees value in continuing a good product rather than starting on a new venture: essentially building up a brand known for specialising in a product, much like Tek & LeCroy did way back when.

Statistics mode should be a few days work at most, just keep a running total and display that instead of the current value.It's a really small investment compared to all the work that's already been done on the firmware, it generates word of mouth advertising, it keeps the existing product line alive for longer.

content: The battery may have been allowed to discharge below its safety cut off voltage that effectively isolates the battery from the scope.In some cases it is possible to carefully apply power to the battery cell string directly (not via the battery management PCB) to slowly bring the cells above the safety cutoff threshold and the battery management will enable the Power MOSFETS again to reconnect the battery to the scope. There are some cautions associated with such action though.1. An isolated battery is isolated for a reason, either over discharge or a fault in the cell string.2. Re-enabling an isolated cell string can ‘re-activate’ cells that have been damaged by over discharge and risks cell swelling or failure.3. Only a voltage and current controlled power supply should be applied directly to the cells and only at a sensible current for long enough to bring each cell up to at least 3.4V. Then use the scopes charging circuit to complete the charge cycle.4. An isolated battery is isolated for a reason …. This is worth repeating ! That said, many Li-Ion/Poly batteries may be brought back to life without safety consequences but some capacity may be lost.5. Some batteries cannot be brought back from over discharge as cells have degraded and the battery management IC detects this and permanently locks out the battery rendering it scrap.Fraser

content: I've been using an STO1104 on a daily basis for many months. I use it in almost all situations in preference to a *significantly* more expensive Tektronix scope (in fact I only use the Tek if I need its higher bandwidth).I've found it mostly intuitive to use, but some things catch me out repeatedly, and there are some things it doesn't do but should. All of these are firmware related:1) Operating the cursor knobs but having to push "shift" (or note that "shift" is active) is a REAL pain. If the cursors are active, the default (non-shifted) knob operation should be to move the cursors! At present the functionality seems reversed between 'shift' and 'non-shift'. In fact the default knob actions for "X" is to select the active wave (not really a common thing to do, and I do that be pressing the channel buttons anyway), and for "Y" it is nothing!2) The measurement calculations for "CRMS" and "Cmean" calculate for the first cycle of a repetitive waveform. It would befarmore useful if "CRMS" and "Cmean" referred to the cursors, so I could measure the part of a complex waveform I was interested in, excluding the rest. I've attached a screenshot - note the "Cmean" shows blank as there is not a full waveform on screen (the duty cycle of the waveform shown is about 0.2%, so zooming the whole wave destroys any visibility of what I'm interested in, and calculating the mean of the full waveform is not what I want anyway).3) It would be useful to be able to 'rename' the channels. For example, instead of "1" and "2", be able to enter some text such as "TX" or "Vgs" instead.4) The measurement text always appears at a fixed location on the screen. Mostly the location is fine, but sometimes it would be great if I could touch at that location and drag the text block to somewhere more convenient.Overall I find the scope very easy to use and love how I can use the knobs/buttons or touch-screen to do things!Cheers, MM.

content: I guess i'll post here on my progress:- The SATO1004 has a aarch64 based rockchip SoC.- First connecting it to usb c and then to AC while powered off, then powering on, yields a screen showing "Upgrade mode".- The device will identify as fuzhou rockchip device and can be read from and written to using rkdeveloptool:https://github.com/rockchip-linux/rkdeveloptoolThis can also be used to create full images of the device's internal memory as well as write them back to the device if anything should go wrong.I will keep you updated if i make any further progress, currently downloading the image from the device to further look into.

content: I was just looking at a the new Micsigs and I don't see a button to go directly to the trigger menu like on the old ones....Is it true?? Surely there must be a shortcut for that.

content: Is the only difference between the STO1004 and SATO1004 the automotive test features?Main thing I'm interested in that I can't find for sure that the SATO version has is the intensity grading, and it's not entirely clear from the manuals or information I've found.

content: Quote from: ruhnet on May 10, 2023, 06:24:28 pmTook a brief look, also cant validate it , when it comes to the intensity greyscale grading or the temperature color corrected, Micisg labels it as "CCT"but Micsigs intensity-grading is IMO quite good with many levels.. can't recall if it's 256 or 512.Micsigs CCT and the adj. BW filters. (both are two critical features, I often use but its the older knob-modelhttps://tinyurl.com/mr35eeb3)Im pretty sure the SATO does have intensity grading, as it would be a weird thing not to implement, but Im starting to second guess, when looking at the brochure's. (English) as nothing pops up when searching for CCT or intensity or grading, but I only just skimped the manual briefly, as it is like 441' pages with pictures, pasted below.Spec.https://www.micsig.com/uploads/MicsigSATO1000Datasheet220817_1660718934.pdfCataloghttps://www.micsig.com/uploads/SATO1004Catalog2022_1660801384.pdfManual.https://www.micsig.com/uploads/MicsigAutomotiveTabletOscilloscopeSATOseriesUserManual_1656581945.pdf--// It could look like the SATO perhaps doesn't have it. as it aint highlighted on the SATO's datasheet, as the case is with STO/C/E & ETO series but I cant say for sure..

content: Micsig STO110E Plus has small bug in channel high/low pass filtering. High/low pass options show nonsense result until some limit value (MHz/kHz) is entered. Limit value by default is blank for high/low-pass and thus by default produces wrong result. Full BW and 20M BW options works fine. FW is the latest available at the time of posting.Setup:enable one channel, AC coupling, auto run mode, measure something stable (output of DC PSU or battery). Zoom in the lowest V/div.Go to channel options, it will show full/20M/low/high-pass selection. Note that limit value (in rectangular window) is blank.Select full BW or 20M BW - 20M works as low pass, full BW shows more noise.Select high-pass. All screen is filled with much higher amplitude wrong signal (oscillation).Select low-pass. All screen is filled with much higher amplitude wrong signal (oscillation).Press on blank square, enter MHz or kHz value. Now low/high-pass options seem to work normally.EDIT:added screen shots.

content: Quote from: electr_peter on September 24, 2023, 02:06:13 pmIt's been like that for a long time like a year or two.... if I recall at least OTA xxxxx28 and xxxxxx29 got that annoying bug with the high & low bw filter going berserk...so I don't use those OTA vers... tend to use the vanilla that is hardbacked.. I reckon it's xxxx08.- but it creates numerous problems also for ref. that will flood the screen.its a shame about the bandwidth filtering, as it's otherwise very good... with manual controlIt looks like they simply forgot to put in the entry values for high & lowpass, which both have manual adj. control, and it will flood the screen with rubbish, and you need to dial in a value before it will play along.Can be seen at 1.05minute below on a STO1104C.. it gives a lot of nonsense..I reckon everybody has gone home at this Mc-Micsig-company and they simply don't give a flying d*uck..but at least I can still slurp the vanilla ROM, back'ed in (xxx.08) which is solid...Micsig bandwidth filtering, and their gradings with CCT, were otherwise top nudge

content: This is a little program I wrote a while back for my Micsig.Normally the screenshots come out a bit dim when copied to the PC. I think the 'scope uses a different gamma curve for the screen or something. This program adjusts it so it looks better on PC.All you need to do is drag your screenshot files (.png format) onto this exe and it will fix them and save them under a new name (same as old name but with added underscore character).Hope somebody finds it useful...Edit: Here's before and after:nb. It's Windows-only.

STO1104C? and what OTA-scope update are you on.?

content: Quote from: DaneLaw on September 27, 2023, 07:53:45 amThat confirms the filter bug, I see the same behaviour. With empty filter cut-off value nonsense is shown on a screen.QuoteI would day that Micsig is not that bad w.r.t. FW updates and is better than Rigol (DL3000 DC load has bugs and so much potential with better FW, but there is zero response so far)There were quite a few Micsig updates, even recently (but just for small bugs IMO, as I didn't see change log anywhere). However, more serious requests for improvements are still on the table (like fine control, statistics trend, zoom bug, etc.).

MSD doesn't complain here...What message do you get? Does it say it's a virus or just that it's "not a very common file" (or something like that).Mine's an STO1104C.
