content: 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.

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/(*) If Micsig wants to send me one I'll be happy to review it though.

content: 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:

content: Quote from: labmixx on June 10, 2022, 04:34:11 amGood 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?

content: QuoteThanks a lot!I'll do my best to improve for future videos.QuoteI 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.QuoteYes, I completely forgot.I got too used to the AutoRange mode haha...

content: QuoteForgot 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.

content: Quote from: labmixx on June 10, 2022, 11:00:31 amFurther investigation needed...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....

content: QuoteDefinitely. 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.QuoteI 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.

content: I loved the display of "NaN" in your video when the serial data wasn't updating.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.

content: QuoteHaha, 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.QuoteI 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.QuoteAgreed, it couldn't be simpler to implement. Doing some running or even total averages costs almost nothing computationally. Maybe eventually!

content: 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?

I do find it very useful to power gear, like fx signal generators likemy 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

content: 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 ofMicsig 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: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).

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.

content: 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 contactor the MicSig probe interface (I have the DP750-100 differential probe) I expect it will be fixed in a future software updateor 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 speakerconnected 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.

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.

content: 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.

content: Quote from: tautech on March 20, 2023, 01:10:35 amIndeed, 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.

content: 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 sensingis 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 thebuilt in stand would be useless.If anyone else has a TO2004 or TO3004 with Micsig probes, are they recognized on your scope?

content: 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.

content: Quote from: nimish on February 23, 2023, 04:41:25 amThis 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.

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 0V0V O O +12.0V+3.31V O O -5.94V

content: @dmeekThe 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?

content: Quote from: skander36 on April 24, 2023, 05:22:19 amI 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.

content: 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.
