Micsig seems about to release multiple new scopes, public on its Chinese website only? : https://www.micsig.com.cn/ETO/ (https://www.micsig.com.cn/ETO/)

At least this one is a real portable scope with an internal battery included ::)
-
Look at the specs...!
Micsig are taking on the big boys now.
At least this one is a real portable scope with an internal battery included ::)
All they need is a VESA mount and a pretty stand with a handle on top. Nobody will buy that new Tek if they do that.
-
I'm not sure that taking away all the buttons is a good idea. There's a few buttons that I use a lot, eg. Zoom, measurement menu, trigger menu. All of those take two or three gestures otherwise.
There's plenty of room for those at the bottom of the 13" screen, they really ought to add them.
-
Agreed! Buttons work for me just fine! Haven't try the new button panel on the Smart series though...

I haven't seen any videos of people using them but they look weird. They're probably good to use with a thumb when you're holding the 'scope in your hand but I can't imagine they're very ergonomic when it's upright on a bench*.
I already mentioned them here: https://www.eevblog.com/forum/testgear/new-micsig/ (https://www.eevblog.com/forum/testgear/new-micsig/)
(*) If Micsig wants to send me one I'll be happy to review it though. :)

1920x1080 ! Suck on that Tek ! (1280x800).
I can;t understand why we are still mucking about with all these low resolution displays. a cheapo tablet has 2500 by something these days... in a 2000$ scope you'd expect at least 1920

Hi guys! First post as this person. :)
I've posted... a unique (haha)... video review of the new STO1004 scope! If there's interest, I may do a teardown as well, but to be honest I don't have too much time to create content like this, so I'd rather spend time making videos with more unusual content. That said, I still wanted to do a good job with this review. I think it covers most things you'd want to know. It's pretty lighthearted, so I hope that's ok haha. English subs are available, and everything is divided into chapters. Subs took a long time to create for 50 mins of video, but I speak kind of fast at times and I respect international audiences a lot. :)
YouTube link to review:

I've posted... a unique (haha)... video review of the new STO1004 scope!
Good video! It really shows what Micsigs are like to use. I was wondering what the new joysticks were like and this answers that. I think I'll stick with my knobs for now though.
I'm not seeing many new features compared to the old ones, mostly changes to the UI - dark theme, slide-out menus for the channels. Turning off a channel looks more difficult. You have buttons on yours but there's two new models without buttons. :-\
The "aux out" connector at the top will give one pulse for every trigger event.
You didn't show the timebase popup or changing the timebase with the buttons at the bottom. I guess you were using it in auto timebase mode most of the time though. I see the auto mode has been reduced to a single button. On mine I can select horizontal/vertical/level independently (see image). Does it scale all three or just the horizontal on this new one?
-

Thanks a lot! :) I'll do my best to improve for future videos.
The "aux out" connector at the top will give one pulse for every trigger event.
I just double checked, and even when I have it set to a short timebase setting, triggering in "Normal" mode, the fastest pulse rate I get out of the Auxout port is 33Hz. As I increase the timebase and grab more points, it only goes down from there. But surely it's triggering on the waveform more frequently than 33Hz? Given that the waveform update rate is supposed to be 130k waveforms/sec according to the spec sheet? I'm using a very fast scope to look at the Auxout signal.

Yes, I completely forgot. :palm: I got too used to the AutoRange mode haha...
-
On mine I can select horizontal/vertical/level independently (see image). Does it scale all three or just the horizontal on this new one?
Forgot to respond - yes, it's the same. You can select all three individually. I just had vertical scaling disabled in my video since I didn't want it to jump around. When I had more than one channel enabled, the vertical scaling was often different for each channel in AutoRange mode, even with an identical signal, which was odd. It works very well for a single channel though.

Further investigation needed... :o
What's your opinion of the joysticks? I'm wondering if you put your index finger on the top edge of of one, can you push it to do an "up"?
ie. Can you do do up/down by push/pull on the edge of one?
In the video you seem to use your thumb more.
What's the response like when you want to move the trigger position long distances left/right? This one probably needs a video demonstration....
-
What's your opinion of the joysticks? I'm wondering if you put your index finger on the top edge of of one, can you push it to do an "up"?
Definitely. It's still easier to put your thumb on them (they have grippy textured tops) and move them that way, only because if you try to move them from the edges, the other buttons may get in the way. The trigger joystick can be grabbed easily from the sides though, and it's easy to move left/right as you describe (which selects trigger channel #). They're also easy to push as buttons, without accidentally tilting them into one of the up/down/left/right positions. To be honest, they do feel good to operate.
The other thing is that unlike a knob that you'd have to keep rotating, you can simply hold a joystick in a particular position (tilted left or right). There is software acceleration, which means that the scrolling speed will speed up over a few seconds, to a point, and then keep scrolling at a "comfortable" speed (slow enough so that you could still watch the waveforms).
I'm honestly neutral on the joysticks. Both joysticks and mechanical rotary encoders will fail over time. Joysticks will probably fail a bit more predictably. I generally prefer knobs, but I don't mind these particular joysticks at all.
What's the response like when you want to move the trigger position long distances left/right?
I haven't noticed any delays in waveform scrolling at all, regardless of number of points or channels. One of the worst things would be to have some intermittent delays (like on some Tek scopes), but it's pretty smooth sailing with this one at least. Even with all channels enabled and with max points, you can scroll continuously with the joysticks. There are no "jumps" or stutters or anything.

I loved the display of "NaN" in your video when the serial data wasn't updating. :-DD
You dedicated a lot of time to that bug but really I don't think many people will be decoding 8MHz RS232 data. I mostly do I2C with mine. The I2C decoding and trigger modes work very well. It also shows all the ACKs and NACKs in the decode. :-+
I'm surprised they haven't added statistical mode yet. I suggested it to them over a year ago and it seems like it should be really, really easy to do. There's plenty of space for a 'stats' button next to the on-screen cursor on/off buttons.
-
I loved the display of "NaN" in your video when the serial data wasn't updating.
Haha, yes, I only realized later that they're simply dividing the number of error frames by total frames received and multiplying by 100 to get an error percentage. Dividing by zero fails, and you get a NaN haha. In the video, I assumed that they were calculating errors based on what's in the buffer, but that's not the case. It's just a statistic.
You dedicated a lot of time to that bug but really I don't think many people will be decoding 8MHz RS232 data. I mostly do I2C with mine.
I agree haha, and I realize that this would be a very rare use case for anyone else. I just thought the way in which it failed to display the characters was interesting. :) Since I wanted to release this review quickly, I didn't have time to plan out any other more elaborate bus decode tests, but I will in the future. Very glad to hear that I2C works well - I haven't tried it yet.
I'm surprised they haven't added statistical mode yet.
Agreed, it couldn't be simpler to implement. Doing some running or even total averages costs almost nothing computationally. Maybe eventually!
-
It could be me BUT one thing I really hate is the amount of space the screen borders take... (1-inch plus)
-
I still think that they owe us that bought STO C series (one with proper buttons and knobs) an update that will give measurements statistics.
That is my biggest problem with otherwise really great simple little scope.
Some cheap 50 USD crap has statistics...
In meantime they developed STO E series, and two new generations of hardware (even segmented capture) but they don't know how to make simple statistics..
New scopes (despite more powerful hardware) are basically same as old ones in capabilities.
While I like the scope and company, I don't think that they can go forward without fixing some of the major flaws.
While old ones were small, simple and cheap but nicely made and useful tools, to move forward (and I presume new ones will be much more expensive) why would anybody buy it if it cannot compete in basic features.
Also, my STO1000C is few years old and seems like abandoned platform.. No new development. Even really simple (and basic) stuff like measurement statistics.. Makes you wonder if that is the policy?
-

The screen's quite big for an oscilloscope, but ... I guess the case is even bigger. :)
-
Seems more or less the same, with specs as the E for the STO1000 (non-C variant)
Model STO1004
Bandwidth 100MHz
Analog channels 4
Sampling rate 1GSa/S
Memory depth 70Mpts
Waveform capture rate (Max) 130,000 wfms/s
Bandwith limitation 20MHz, High Pass, Low Pass
I/O port Wi-Fi, USB 3.0/2.0 Host, USB type-C, Grounding, HDMI, Trigger out
Display Industrial 8 inch TFT-LCD (800*600)，14*10 grids
Dimension 265*192*50mm
Battery 7.4V，7500mAh
Dimension has changed a little from the STO-C model.
New STO1000 series 26.5x19.2x5cm
Checked the older STO1000C 28x18x5cm so the new (non-C) is a tad higher +1.2cm and -1.5cm shorter.
Looks to be the same 8" 800x600 TFT from the previous gen's that obviously chokes from a low-based perspective, as TFT usually does.. and it's not a bad TFT screen per say, and quite useable outdoors with peaks up around 415nits, but that is obviously taken under different aspects, while in browser to pursue a white background and not in the scope app.
TFT LCD screens seem to be common in electronic measurement gear, as we also see a TFT in the new MSO2x- series from Tek.
But definitely, not a fan that Micsig ditching the clickable-rotaryknobs for some small 4way joysticks..I keep coming back to using the knobs.
One thing I really like about these Micsig scopes - is their color intensity (CCT) and also their overall intensity-grading that seems pretty high in grading-number.. like up around 256 levels, certainly decent..
Checked the wfps on the older STO-C model - as far as I can tell, it peaked at 103.000 but mostly was around 95.000, but I was using limited gear - to take the freq-reading, and will obviously vary greatly on the settings.. https://i.imgur.com/nNcrhSz.mp4
but around 100k, as wfps peak number' ain't bad in this handheld price-segment and the official specs claimed above 80.000 - if I recall correctly for the 1000-C series, so it seems to fit.
I like that they added more USB ports on this 2022 variant, even USB3 and TypeC.. I do find it very useful to power gear, like fx signal generators like
my old FY6900-60mhz or extra displays etc, with these USB ports..though, im not sure the purpose of them in the new model and to what extent you can use them.
I don't use it for video or pictures etc, as its so much easier to just log onto the scope's IP in a browser, and download content by WIFI.
On the old C-model and power, I tend to use either power delivery (PD) TypeC power banks with a TypeC to Barrel DC PD-trigger-cable (12v) or these adjustable 3v to 24.6v DC power banks that can go up around 100watt, as the included 12v 5A PSU is a noisy fellow.
The old model consumes around 21 watts when charging the inner battery, while turned off, - and in use' it peaks around 31watt when I looked at the power bank display, so it ain't a lot it's using.. and should be easy to supply 12v power on the road

You can actually hold it for something while having unobstructed view of the screen.

Does Micsig use the same product numbers for each new generation? I've seen some sto1000 series with reviews from a few years ago but these new ones are also sto1000? is it the letter at the end? like the C? Thank you!
-

The numerical part is the bandwidth and number of channels.
eg. 1004 = 100Mhz, 4 channels.
(many manufacturers do this)

Thanks, yeah, i figured that part, but then how would one know it's the new or the old version if they all are STO1004 for example? like Siglent names have an X or an XE or an X+ and that differentiates the new ones from the older ones. How does Micsig do this? I've seen some have a C or an E at the end of their name, do they do that in order or is the letter for something else? thank you!
-
Looks like the prices for the blue ones have been slashed to make way for these new black ones.
eg. STO1104C for 475 Euros

Grab 'em while you can!

I've posted a followup video for the STO1004 which covers (in that order):
-Wireless USB dongle fix
-Responsiveness issue at 70Mpts
-Random double clicking issue
-Remote control app
-Joystick feel
Thanks again for the feedback guys.

Thank you labmixx for your nice and professional video.
I like your sense of humor.
I have 3 questions about Micsig's new STO1004 scope:
1. Is there possible to switch between impedance: 1MΩ" and 50Ω?
In the documentation of Micsig STO2000C, chapter: "5.4.6 Channel Input impendance"
there is information: "you can choose "1MΩ" or 50Ω", the default input impedance is 1MΩ."
2. How it works "Segmented Memory Function"?
It is a real "segmentation"?
See: https://www.youtube.com/watch?v=LJaGVBUVQB4 (https://www.youtube.com/watch?v=LJaGVBUVQB4)
In comment related to this video you can find:
"On my STO1104E, when I go to the top menu, and go to Sample, my only options are “Sample” with Normal, Average, Envel., and Peak. I don’t have Mode, Depth, and Segmented Storage. I went to System Upgrade, but it says “No new version”. Can you tell me what to do to get the Segmented Storage, Please? It looks like a really cool feature, I would like to check it out"
3. Is there Pass/Fail Analysis analysis?
Thank you :-)
Maybe function 1 and 2 will in higer model(s).

Have they published a price yet?
Took a brief look in China on Taobao.. atleast two listings for the TO3004
One was a tad over 22k CNY (3250 USD) and the other were at 16.990 CNY (around 2.500 USD) and didn't see any noticeable differences to explain the price difference, both TO3004 with serial decoding...seems these early prices. are likely inflated with a decent third-party mockup
300Mhz, 2GSa, 220meg, 10.1 (1200x800 TFT-LCD) 1.9kg
CN specs.

https://www.aliexpress.com/item/1005004634051818.html (https://www.aliexpress.com/item/1005004634051818.html)
But anyone know where to buy that big screen TO series? No link from aliexpress and even official website

Taobao had a few listings of the TO-series 10.1" (1280x800) but it seems to be a lot more expensive, as I mentioned above with some price examples from Taobao.(though' not sure what kind of mockups there are in those price examples and were a given MSRP actually are on the TO series )
But in short while, I reckon the TO variant will be present on Aliexpress or perhaps Bangood or Amazon or third-party regional western sellers.
There is also the new ETO series that has a 14" (1920x1200) screen, but that will be even more expensive..
Bandwidth: 500MHz - Sampling rate: 3GSa/s - Storage depth: 240Mpts

(Plus you can get VAT refund if you're eligible so that's another 100 Euros)
But anyone know where to buy that big screen TO series? No link from aliexpress and even official website
I don't think it's released yet, it's under "roadmap" on the Micsig web site. It does say "2022" though so it should be soon.

I told you above, a few weeks ago - when you asked about the price on "TO-series" that it has been released and you can purchase it from Taobao and I even listed the prices with USD currency, but it seems it went over your head, even though its like 3 post above.
- I even mentioned it again today, 1 post above yours..
Are you familiar with Taobao.?
it's not easy to link there, as links seem to be account-depended but it's a Chinese wholesale platform, like fx Aliexpress etc. that often has more regional Chinese test equipment.
and yes.. they have been released and been open for purchase for like a few months.. are in stock and shipped in 48 hours.
at least 4 different sellers are listing it, and it seems that the price at (17k CNY) is more or less the norm..for the TO3004. which is equal to 2500 USD before EU VAT, so quite a step on price in regards to fx STO1104C that was down around 400 bucks., but obviously also another bandwidth.(300MHz/TO3004)
If TO-series will be released in more down-to-earth bw-specs for less coins.. I don't know and I would also check with sellers if the English language is implemented, before thinking about importing, usually it is from scratch, as it's part of the development.
But generally, it will take some time before items come to western regional resellers and many items don't, not least the more expensive Chinese branded testgear.

I see, the ETO (gen5)..no that unit aint for sale yet.
the ETO is still under roadmap. and also don't recall I have seen any videos with it, also no videos on Chinese video-hosting platforms..
Got no idea where ETO unit will land price-wise..when the TO3004 is already up around 2½ grand.
The TO3004 (10.1" 1280x800) does seem to have an official MSRP in China of 16.998 CNY (2.5k USD)

I'm a long time analog scope user, mostly Tek 7000 Series. Just bought the TO2004 and I'm very happy with it.
The only problem I have found is the scope does not recognize the probe attenuation ratios either with the BNC ring contact
or the MicSig probe interface (I have the DP750-100 differential probe) I expect it will be fixed in a future software update
or I'll contact MicSig about it.
I've already cracked it open to add a channel 1 output. I work mostly in audio and I like to have a small amplified speaker
connected to the output.
My modification is below. The 100K resistor will hopefully protect the scope from the outside world.
I would post the photos but I can't figure out how to do it.

Hi dmeek,
welcome to the forum. Adding your photos is not that difficult. Just click the attachments and other options below the edit window. Best not to use the drag and drop option or the first file select. Instead click the "(more attachments)" and use the browse button that is then showed. Select the file you want but make sure it is not to big and has one of the allowed formats. Leave the option next to it on "End-of-post expandable thumbnail"
Repeat this action for additional attachments.
This way you avoid the bugs that the system has.
To have your picture bigger and within the text, there is the modify option to do this after posting. The attached file then has a link to where it sits on the server and you can use this link in the [ img ] [ /img ] tags. (Button in the bar above the emoticons sets the tags as they should be, without the spaces that is)

Here are the photos (I hope)

Any news on the 500MHz one?

TO 3004 is the noisiest scope I had.
Is like a vacuum cleaner. Fans are working at full speed all the time.
It seem that the more processing power for the new fancy and high res user interfaces is coming with a price: noisy fans.
Also the "knobless" operation is awfull.
Clever design with two ADC, where you still have 2 GSa/s with two channels and 1 GSa/s with four channles.
For a 1K Euro scope they should put more attention into it.
Or they will adopt Keysight way and will say that this scopes are designed to be used only in auto shops and other industrial uses where their noise is not so obvious, and not to hobby and household uses. :D

Sounds like a WaveJet from lecroy... :D
It´s name is program, never heard such a loud scope...

Many 2000 series DSO's have used this design principle for years, even decades, it's nothing new.

It's not new for sure, but rare for chinese scopes. Rigol5K in 2 CH configuration remain with 4 or even 2 GSa/s.

Good to know , although I don't thik I will ever use a Lecroy as a hobbyist.

Not so !
5k AFAIK uses a homespun ASIC, it's different !
SDS2000, SDS2000X, SDS2000X Plus, SDS2000X HD and SDS5000X for all their 4ch models use dual ADC's.
So does the $499 SDS1104X-E.
SDS6000A uses 1 for each channel like many now old scopes did but they never had the memory depth anything like the modern DSO.
Can't offer further info on other Asian brands as may be incorrect.

Older Rigol DS4000 series used 2 ADC too.. GW Instek 2000E series also.
It is actually quite common technique..

I know you know, I added to your list... ^-^

Is not about that there are two ADC, but that with all four channels activated, you still have half of GSa/s instead of quart.
Anyway the post was more about the noise of this scope. which is annoying.

Indeed, I've checked. Quartation of sampling rate on four channel is more common on Rigol scopes (HDO1k,4K, MSO5K, 7K, 8K) while Siglent has many models that keep sampling at half on four channels.
My intention was to say something good about this scope along with my complain about it, but if the vendor does not come with a solution for noise I think I will return it.
Big difference compared to TO1152 whose noise was barely audible.
Also the battery is draining fast with two fans at full speed all time.
-
I use my TO2004 daily and hardly notice the fan noise. Maybe with the TO3004's higher bandwidth, it has a more aggressive cooling system.
I control mine with a wireless mouse, don't use the touch screen much though I have no complaints about it.
In my last post I noted that the scope was not recognizing the probe attenuation factors. After the recent software updatethe BNC X1 X10 sensing
is now working but the Micsig probes are still not recognized. I have a DP750-100 and CP503. I have to set the ranges manually.
The update added a 180 degree screen rotation function so the BNCs would be on the bottom. Of course you have to figure out how to mount it since the
built in stand would be useless.
If anyone else has a TO2004 or TO3004 with Micsig probes, are they recognized on your scope?
-
I don't have active probes to test, but as you say X10 probes are detected.
I also opened mine to see If I can do something about fan.
Seem to be identical with the 2004.
I don't know what can be improved on the fan, other than finding a better quality one.
I'm afraid to modify speed as in this case the calibration cannot be guaranteed.
It runs quite hot without fans and shields.
-
Any news on the 500MHz one?
This model is still currently advertised only on Chinese Micsig site and pictures seem to be renderings.
It is available only a flyer for it and not a user manual so I dont think that it is currently on sale.
But I don't know who will be interested given its propietary inputs MicOpi. This is the only available version, not BNC.

Hi dmeek!
I have aquired DP750-100 and it is recognized and scope show when I change factor from 50 to 500.

Thanks for the info. I'll contact Micsig and see if they have a solution. I don't really want to have to send it back though.
Here are the DC voltages I measure at the interface:
+4.97V O O +3.31V
-5.00V O O 0V
0V O O +12.0V
+3.31V O O -5.94V

@dmeek
The measurements on the scope side are correct.
The same values are on my scope.
Maybe the probe is not ok. Contacts or internals. The leds on it are lighting? Can be manually switched? Relay from Y side cable is clicking?

I have 2 DP750-100, both working but still not communicating with the scope. Contacts are clean, LEDs light, range button works, relay clicks on both.
I've been in contact with Micsig, though no solution yet. While re-testing all my probes I was surprised the find the CP503 is now recognized and 100% working.
So it appears the scope is OK. The mystery continues.
-
I would make pressure on seller for this. They should exchange probes with the good ones.
Is about a Micsig scope with Micsig probes.
There is no room for tolerance here.
-
To follow up on this. I contacted Micsig and they said the probes needed to be re-programmed. They arranged pick-up and paid shipping. I have them back now, working.
I found Micsig responsive and helpful. It was a little bit of trouble but all is OK now.
-

Yep. Micsig answer emails very promptly and make an effort to fix things.
(in the two times I've dealt with them, at least, and other people have said the same)

Well, happened to asked one of Micsig's domestic sales, says they are optimizing the TO2004/3004 software and probably a new hardware.

And how can this "probably" help with my problem?

Micsig performs well, nice
