A few groups at my office are interested, though being a large company we obviously buy the full spec needed. For day to day problems we'd get more use from a handful of these than one Keysight DSO3034 series, and for a lower cost. Normal caveats apply, w.r.t. right tool for the job, some problems require a higher spec 'scope.
Maybe email them and say "if these had serial decode we'd buy xx of them " & see what their reply is...

Another important feature that is over looked in oscilloscopes is trend plot and scope  record such as that seen in the fluke 190 series. For plotting a graph of frequency vs time pulse width vs time AC peak amplitude over time etc.  Very useful feature for findng glitches and drop outs.  I see this oscilloscope has roll mode.

Apparently serial decoders are in progress when I last emailed them 2+ weeks ago, hopefully they'll turn up soon. But it's worth waiting a little while for them to get it right. They might even include some of the other suggestions here.
I think they've done a decent job on the UI, looking forward to trying new features when they arrive, hoping they don't clutter the UI too much. Probably just another "top menu" tab, along with trigger, measure etc.

Sorry for asking this, but how would this compare to a DS1054Z for a beginner looking to buy its first oscilloscope ? It seems that the main downside of this oscilloscope is the lack of a serial analyzer, but I think I would be fine using a cheap USB logic analyzer for that.
I would mainly be using it for low level hobbyist projects and repairing electronics, for which if I understand it correctly (please correct me if I am wrong) being battery operated would make it safer for diagnosing problems with mains powered electronics and power supplies.

I was in a similar position a few months ago, currently I use a DS Logic  USB logic analyzer (16 channel 100Mhz) with 16M sample buffer for serial decoding and digital work.
As a hobby user I've found the Micsig easy to use and intuitive to use, and has all the features I need, the battery power and small desk footprint I find useful. Given the limited desk space at work it's also a handy desk scope, especially since you don't need to hunt around for a power socket each time you use it.
You can see the review I wrote on the forums.
Everyone that owns one has been been positive, I prefer it over the Rigol, but I'm keen to what other people's views are.

Remember that the channels aren't isolated, so if you connect it to anything such as a USB port or HDMI, or use the charger (1k ohm to earth), it will not be floating.

Although it's early days personally I still much prefer a proper bench scope, but that's what I'm much more used to. I do use tablet devices extensively for other things, you can probably tell from all the typos I make. So given the choice between this and the Rigol in most cases I'd definitely still reach for the Rigol. I still like my knobs and buttons!

As I said I'm not all that used to touchscreen UIs so some issues may have been my own hamfistedness.
Having said that the pinch/stretch to adjust time/voltage range is definitely something that ought to work but didn't.

I think a touchscreen interface done well is an idea whose time has come. A new generation completely comfortable with touchscreens is ready.
A touch screen interface is easy to get used to. Lack of protocol decoders is an excellent excuse for me to postpone buying one. Hopefully the special offer will run out as well to reduce the appeal so I don't have to break my 'no more than 2 oscilloscopes' rule.  8)
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Following a hint from davidefa I've added support for upgrading the memory depth (to 28M) to the config tool.

I don't own a Micsig scope yet, but I'm interested in trying to package this as a fake firmware upgrade. That would simplify the process somewhat. So if someone here owns a not fully upgraded scope and is interested in being a guinea pig (I don't think there is a chance for bricking the device), please contact me.

Cmpxchng - any chance of you investigating similar upgrades on the MS handheld scope meters?

I was thinking the "Ver" label on the silkscreen could be a "version" label and the jumpers below might change whatever option that is being called "version."

The fans noisy, they could have used better material to  reduced the noise from the fan a bit of an annoyance. Also as for software options it would be nice to see some features added as I have mentioned above.  Add power quality analysis like that seen in the fluke 125 and some protocol test functions filed bus etc. Other functions such as graphing functions found in some automotive scopes like the snap on vantage.

If these people want to make a scope that will shake up the market then these feature will certainly do that if added.

I'm guessing some people will be using this out on the field and these features would be quite useful.

Someone in the debranded scope thread has already decrypted the firmware images for the handheld scopes, but honestly they are much less interesting to hack because they run some RTOS on a TexasInstruments DSP instead of just ordinary Linux.

Bah! Humbug!-------a real Oscilloscope has knobs!!!

Touchscreens?,Gestures?

Can you elaborate on this ? All the firmware update methods mentioned in the documentation are done through the tablet UI, so at the very least it requires a device able to boot. Do you have a method for updating the firmware if the device doesn't boot, say, from the bootloader ?
I have ordered a TO1074 from batronix and I'll be happy to serve as guinea pig, just need some reassurance that it *really* can't be bricked.

Also, while looking for more info about this tablet I found this video:

It seems to imply that there is a beta version of the firmware 6.7.0.212 that is able to record videos to USB disks, although I have not been able to find this version on micsig's website.

Is there a record icon somewhere I'm not seeing? Or could that just be HDMI capture?

It's in the video description actually, I couldn't see any hints of the recording UI in the video itself either:

Micsig tBook mini/TO1000 series' new feature as VideoPlay.

Now we can record the LCD display view directly to UDisk(USB Flash Memory).
I coild watch this avi.file with PowerDVD16.

70Mhz version of the micsig TO1074

fed with a  250Mhz sinewave.

And what is the attenuation? Test setup?

Just feed the output from a hp network analyser no sweep just a fixed frequency. In this case 250Mhz
And a terminator at the scope end at 50ohms.

I wasn't thinking in terms of having a low-level firmware flash procedure available, but from what we know the firmware update in the tablet UI does - it simply extracts a shell script from the update image and runs that, there is no reboot into a bootloader, erasing or anything. So unless the shell script intentionally bricks the Linux there isn't very much scope for it to go wrong.

In any case, before trying that it would be easier to look if the FTP/Telnet access is still enabled. That's certainly simpler.

Ah right, if all the updater does is run a shell script then I can see how there is very little risk. Thanks!

All the hands-on comments seem quite positive. Instructive to refer back to an earlier thread where this type of scope got absolutely thrashed by experienced commenters:

EEVBlog disses Micsig

I'm sure there's a lesson or moral or something in there somewhere  :-+

[Disclaimer: I was dubious about not having physical buttons and switches, but having since used touch with its drag and pinch and stuff on phones and tablets, I wouldn't mind playing with the same UI on a scope. Having just bust the entire years toy budget it's not going happen just yet, though...]
