Great! I'd love to read/see more about how this scope works and have been hoping someone could do an in-depth review of it for a long time!  :-+

I can see your ground leads  ;D

Have you tried with a coaxial cable and terminator? BTW nice scope, I would almost use the word cute.

On the paper and on photos it looks pretty good. Have you ever tried to measure the actual waveform update rate at different settings? How does FFT looks?

I just got mine in.  I got the TO1104...this one:
http://www.ebay.com/itm/322331129117?_trksid=p2057872.m2749.l2649&var=511235705607&ssPageName=STRK%3AMEBIDX%3AIT


I love it so far.  What a complete departure from the status quo.  Plus, it takes almost no desk space.  HDMI out is a bonus.   I'm still throwing the kitchen sink at it.  I'll see what it can tolerate.  My Marconi threw 300MHz and the scope just sort of aborted any attempt to figure it out.  I could lock on to the signal up until then.  I still need to plug in a USB mouse and play with that feature.  What is pretty damn astounding is the software doesn't have any crude spelling/grammar errors.  It looks like a professional job. 

Anyhoo...they gave me some software freebies for $300 total because I ordered it before 12/31.  Oh, I paid 10$ for the wifi add on.  Big deal.

I'm not clear on the model numbers. The Ebay listing says 2.8Mpts for the TO1104M but their website doesn't list this model. On Micsig's website I can find the TO1104 model which specifies 28Mpts per channel. Is the Ebay listing for a lesser model? If so then it may not be such a good deal after all. Batronix has a 40% discount on the Micsig tablet scopes as well.

In January 2016 I bought the T202 the 200Mhz model 2 channel.I love that scope and so has everyone that comes in contact with it. So, far I have had no probelms or issues with it and it is heavily used on a daily basis. The only thing that I did not buy was a the fabric case for it but, have a perlican case that I transport it in.

Is the blue molding around the scope rubber? and is it removable?  When I purchased my scope T202 it did not have this protective molding.

Thanks,

Nicholas

Cool! I'm looking forward to your review.

I agree, what's missing is a reasonably detailed independent video review of any of these units. Just an unboxing video has little value. We need to see these things in action, particularly their responsiveness and UI in practical use.

I think Dave had a Micsig and did a teardown, but not a review. I had kinda drawn my own conclusions as a result.

Are there any decode options?

It looks very light and with the probs connected at the top there is a good chance the thing could topel over forward.  The price is also not competitive with a traditional DSO, too high.  If the pricing was about the same to compete with a good quality portable multimeter then it would be a definite winner.

Pricing ( at least the 100MHz versions) isn't that far off a similar benchtop scope, with the added advantage of large screen and portability. rememeber it has intensity display and reasonably high update rate, so more comparable to Rigol 1074 etc.
Also has HDMI which is rare if not unique at the moment
What is a bit confusing is thw attatched part of the Aliexpress listing, which implies some ridiculous granularity of options, though currently showing as included as a freebie

Well, a 2 channel 100mhz portable (if you really need it) scope for 379€+vat is pretty good in my opinion

I've had mine for ~1 month now, and been really pleased with it. Small desktop foot print and big screen is great for home use.
No obvious flaws yet, and the people at work who have tried it also found it easy to use.

Got it this afternoon - played for a few mins then took it apart.
Initial impressions pretty good. Internals pretty impressive ( more so than the casing) , in both design & build.

The same can't be said for their terrible, confusing ALIexpress shop pages.

First scope I've seen that has stereo speakers!

Actually they're on the top on the one I have - not sure if it's a different model or different revision to the pics I saw, also mine has a micro HDMI - I'm sure some of the pics show a standard or mini one  - the Aliexpress store pages are extremely confusing about the various models & variants - need to take a good look through to try figuring it out.

What model did you get ? 70mhz or 100? 4 channels or 2?
Im thinking of getting the 4ch 70mhz Model, and maybe in a future thread we should study the hackability from 70 to 100...

Mine just arrived, a TO1104 from Batronix, 4ch 100MHz 28Mpts WiFi version.

I'm out at a customer at the moment so not much chance to play. It's about the same dimensions and weight of a 350 page reference book. Very first impressions are: (a) the fan is quite noisy, but that doesn't normally bother me too much, and (b) the screen updating and UI don't seem particularly fast, but so far it is responsive (there's a difference!). For very basic functionality the UI is reasonably intuitive to use. For some things like zooming it has its own multi-finger gestures which aren't immediately obvious, I needed to RTFM to find the three finger zooming gesture, but once you know they're easy to use.

As well as a reasonably healthy discount Batronix threw in a non-autoranging UT151 multimeter which I can't see finding its way out of the box let alone being used. The one I have included strap, battery and WiFi. I haven't figured out how to attach the strap yet: threading the velcro through the holes looks like an exercise in logistics.

My ten minutes with it suggest it's not bad, but I'll reserve judgement until I've used it in anger for an hour or two on a real project.

There seems to be quite large price difference between 2.8 MPts and 28 MPts versions.  I wonder if the (I assume) DDR SDRAM is populated on the 2.8 version anyway and requires some option key, or even if not, it might be possible to solder the missing chips.

I get the point of optional features that required considerable effort to develop & test, protocol triggers and decoders, analysis software, but some extra memory, that was in the design from day one? The only mass produced memory I know that would cost so much for 25 MB would be probably Xeon v4 on die L3 cache.

FWIW it appears to be reasonably locked down. I may well be mistaken, but I haven't seen any obvious way of even pointing the browser to anything but the micsig website, or installing APKs for example. I'm assuming it's Android under the hood, but ISTBC.

Not sure if it's Android or Linux - it's pretty well hidden. Forgot to look for serial port on PCB.
There is an FTP port open, and for the hardcore hackers, the onboard flash is an eMMc

AFAIUI none of the tablet ones do, apart from the isolation of running it from battery
Something I thought to try then thought better of  was to  float the scope ground to mains and see how well the touchscreen worked ;D

Not on the TO1104 I have. Be aware that there is also a 1k ohm impedance to earth on the supplied mains PSU which uses a three pin IEC kettle lead.

Well spotted - I looked at the cracked-open PSU and assumed it was directly connected. There is a resistor and parallel capacitor, probably better than a direct connection, and certainly better than floating at half mains from an ungrounded PSU.
Interestingly the PSU is rated at 2x the maximum draw when running and charging a flat battery - I wonder if they chose this as it had the 3-pin input, whereas smaller ones often are only 2-pin.
Or could just be they use the same PSU for the 10" version which has a 10AH battery so maybe higher charge current.

I haven't figured out how to attach the strap yet: threading the velcro through the holes looks like an exercise in logistics.

Folding a length of sticky tape over the end of the strap, with some bit of overhang for easy poking through has helped me at times on other straps. Not actually tried it with Velcr though.
Mine came already threaded, though it was listed seperately on the packing note. Possible they did it as they knew it was me....

Mike: bummer that they gave you non-M version ;), now we won't know how to update 2.8M versions to 28M.

Internally it looks very well, a child of Rigol DS1054Z (ADC, Spartan-6) and Android tablet :)

Rigol, AFAIR, has additional Cypress SRAM attached to the FPGA, presumably to render the intensity grading. Here either they have beefier FPGA version (more BRAM), or maybe the CPU is doing more, as it is significantly more powerful than cheapo Freescale iMX that Rigol has.

If they stop being silly about the $7 options and add serial trigger/decode then this is a very serious competition for Rigol. I bet a lot of hobbyists would pay a bit extra and have a scope that can be used both on the bench and in the field.

I just quickly glanced over the firmware update files they offer on their website for the TO1104 because I was curious what operating system they are using.

The files seem to be encrypted using AES ECB. The entropy is pretty high. Only in the first few kilobytes the same 16-byte pattern repeats over and over again.
There are a few exceptions in this block where the pattern changes. But it does so always on a 16 byte boundary which leads me to believe that they use a 128 bit block cipher in ECB mode just for the purpose of obfuscation. AES is just a guess, but what other block cipher would you use?

So, somebody should dump the eMMC.

I suspect Android, but fairly well hidden - the larger ones definitely are as I've seen an Android logo onscreen in an old review.
Forgot to look for a serial header - will take a look when I get a chance.
There is an FTP service which may be worth investigating.

Watched the first 20 mins on my commute this morning, and I'm feeling slightly dejected, mine came without condoms.

I find the tilting bale is too stiff to open easily, you need both hands on mine to set it up.

Having the probes coming out of the top is less convenient than out of the side, I find the resulting cable management less than optimum. It also makes the effective height on the bench quite a bit higher, so if you have a monitor on the bench you will find either the probes get in the way or you have to move the scope or monitor off to the side.

I totally agree regarding the confusion around models, versions and options. You need to do quite a bit of digging to come to any reasonable conclusion.

I was debugging a reluctant SWD interface on a Cortex M0 with it last night. I do like the touch zoom when navigating a long waveform capture.

Serial trigger and decode would be a great option.

Boot speed even from a cold boot is good, 15s or so. From standby it's pretty much instant.

I'd like to see any recommendations for a close-fitting protective sleeve which isn't too bulky and has probe pockets.

Sorry if some of my comments are already covered in Mike's video, I haven't seen the last 40 mins yet.

Yes, it is fiddly - definitely could be improved - just some grip ridges on the sides would help

On balance I think top is better as side would constrain where you could put it - space upwards is generally more free than space at sides. You could always get some BNC right-angle adaptors.

They do actually do a carry-case - didn't look to see which model it's for bit it's crazy expensive, like about £60

ISTR the dimensions are rather out of kilter with the scope's size, although I'd probably pay to see you turning up on site with your handbag:

"Handbag?Black nylon dimension 300mm*410mm*130mm"

Regarding the probes coming out of the top, it's a minor thing but as well as getting in the way of the telly, I found the probe cables ended up draping themselves over the front of the screen. Not a big deal to flop them around the back, but it just didn't seem the optimum position for them.

I did measure the trigger out last night, and most of the time despite advertising 80kWfm/s it was usually much lower than this, about 2kWfm/s. It did, on brief occasions, hit 70kWfm/s but that was the exception rather than the norm. Please note that this was only a brief test, although I did try to optimise the test signal and the scope configuration to maximise update rate. Removing measurements and switching to dots, for example, made a very significant difference.

I received yesterday my TO1074 unit ( from batterfly ). Including:
- battery ( as specified )
- wlan option ( not specified as included, maybe a limited demo? )
- hdmi option ( not specified as included, maybe a limited demo? )
It didn't include the strap ( need to find an alternative strap ), not specified as included, but a scope like this need to include one

ftp access: user ftp, password ftp
telnet access: user root, password micsig ( not that difficult ;-)

interesting files are in /home/micsig directory

Software improvements:
- protocols decoding
- segmented memory ( and good searching options )
- data recording directly on disk ( low speed is ok )
- last... yes I have a dream ( that will never come true )... a software toolkit/plugin/scripting language/something else... to write my own software that extends the scope software

P.S. my software version is 6.0.125 in micsig site found that last is 6.0.204beta, but reluctant to upgrade, no changelog provided
What is your software version ( in Mike's video I see a few options missing in mine )?

Regards

Quite a few option links on the bottom, would be interesting to compare different models.
Bottom row are definitely options as they are pull up/down.

The button on the battery PCB looks like a shipping lock  - cuts power instantly, resets by connecting charger
As expected, the one on the main PCB is a duplicate of the power button

Regarding isolated inputs:

Does the website clearly indicate whether the model in particular has isolated inputs or not?
Some models do, while others don't. So I hope it is clearly specified for a specific model.

Regarding overall build quality:

It is surprising that the PCB board itself shows high quality, but that they did such an extremely poor job on soldering the BNC jacks of the front-end input to the PCB board, as shown in the video of Dave Jones.

Maybe that unit in particular was a pre-production demo unit with some open quality issues?

Can someone who is in direct contact with Micsig Product Engineering department, ask them about this quality issue, and have it confirmed that in final production units there is a decent soldering joint for the BNC input channels?

I would like to see a BEFORE and AFTER photo from Micsig to get confidence that this problem is solved now, before pulling the trigger on the ORDER NOW button :)

The Micsig website shows that only the MS300 and 500 are isolated.

The "disable gradient waveform" control (3rd button along on the pull up menu from the bottom of the screen), enables a "high speed" mode, and brings up a red H on the status in the top left.
This both disables the variable brightness AND sets the all the entries in Userset->Depth "auto", the excellent video mike did mention he's seen this but wasn't sure what caused it.

In this High speed mode the waveform rate went from ~2K to ~30K.
To get a higher frame rate I set Display->Waveform to dots, and Display->Persist to None

Configured like this I've seen bursts of ~180K waveforms per second captured, with the average over a second as ~140K samples. (see attached diagram of trigger out, logged with an 8Mhz input signal)
I did notice it didn't achieve the highest rates on fastest timebase but required backing off to 50ns / division.

Micsig support quite responsive while I was trying to get the waveforms per second number up.

I've not  discovered how to change the SD in the status on the top left yet, or what it stand for.

A did also contact Micsig about the lack of serial decoders which are in progress and segmented memory, (also useful for going back to look at serial packets).

The MicSig user manual for their handheld scopes (I recently bought one of the debranded eBay bargains) says that the SD and the number next to it inicates the current channel memory depth.

The nasty little thing wants to autoupdate.
I was testing the battery life ( stopped the test after 4h 20', with the battery icon showing some 'juice' left, quite happy with battery life ) and the scope notified that an update was downloaded and ready to be installed.
And yes, in the background it downloaded 15M of software 6.0.186 ( a config.xml file it downloads call this version 601.0.186 and/or 6.0.186 )
This happened after I enabled wlan connection.
I'd like to stay on my old software ( not to lose telnet connection )

There is a 7GB device ( /dev/sdcard ) mounted on /sdcard, it contains the four directories available via ftp/usb, think is a simulated SD card

Yes.
Additionally an inserted usb stick is automounted on /udisk, so
If someone want to take a glimpse to the software it will be available at the following link ( the text file included is a partial log of a few telnet sessions, it includes the output of the 'ps' command )

P.S.
If you want to take a scope snapshot via the web interface you can point the browser to cgi-bin/autoplay.cgi
It will refresh the page every 5 sec ( it will also modify the screen.png image every 5 sec, so not a good idea to stay on this page forever )

It's certainly full of GPLed software. They have even helpfully left the symbols in for the main oscilloscope UI software. This would make a great hardware platform for an open source scope.

(Most importantly, the oscilloscope software and other parts of the system are linked to Qt 4.8.7 open source versions, which means that if you have bought this scope, you are legally entitled to a copy of the source code of their oscilloscope software and lots more)

For those playing along at home, firmware updates are retrieved from http://www.micsig.com.cn/upgrade/config.xml

The .bin files consist of 37912 bytes of header and the remainder is data, both "encrypted" with a fixed AES key in ECB mode (hence the repetitive 16 byte blocks, particularly in the header which is 99% nulls)

The AES key used is
Code: [Select]
\x19\x05\x14\x20\x11\x27\x27\x11\x06\x05\x13\x20\x20\x03\x84\x19\x09\x02\x89\x19\x27\x03\x12\x20\x16\x05\x12\x20\x31\x09\x12\x20
Notice that 37912 is not a multiple of 16 so you can't just decrypt it all at once as the data isn't 16-byte aligned. The decrypted data then will be a Makeself shell-script (https://github.com/megastep/makeself) that the scope just runs. The shell script decompresses the actual firmware, which is a .tar.gz appended to the script. This archive doesn't contain the entire filesystem, just the Micsig binaries for the oscilloscope software, settings etc. and a few files that are selectively copied to other places such as /usr/lib.

The system isn't Android but rather a normal Linux (OpenWRT?) and all the interface stuff is done with Qt. Since updates are retrieved over HTTP, not signed and simply executed after download I wouldn't really recommend connecting these tablets to the internet.

After a couple more stints with this, as well as adding to the wishlist of serial trigger & decode, plus direct access for Auto/Normal triggering, a direct access for Default Setup would be nice. There's a Factory Reset which seems to do this although it sounds more fundamental than Default Setup, but it's a couple more clicks away than I'd like. I have become used to the UI more quickly than I anticipated, but I still have some niggles about trying to find some non-obvious or hidden features buried in the menu system.

In single channel mode on my example, rise time is 2.66ns and 3dB bandwidth is 150MHz, both measured using an external 50 ohm BNC inline termination. For rise time I used an HP 54121T with a measured system rise time of <33ps, and for 3dB bandwidth I used an HP 8656B RF signal generator with 3Vpp signal.

This scope at the current price point has the makings of a seriously useful instrument. If they wanted to really shake up the market, serial trigger & decode would be the way to do it. Cleaning up the UI would be nice. It's somewhat frustrating that something that's so close has a few too many quirks in operation, as if the UI's been designed by software developers with little input from hardware engineers.

Micsig are clearly moving in a new direction with the tBook Mini, as their earlier devices were aimed at a very different market.

The TO1104 I purchased from Batronix was €539 ex-VAT as there is currently a €360 discount on this model. It has all the current options installed except 500uV and the extended warranty, and comes with a battery and carrying strap (that I still haven't figured out!). From Mike's video it looks like you can't just throw in your own battery, it has a bunch of proprietary electronics that comes with the battery.

If you're going to buy one check the following options to help you make the comparison:

Channels, 2 or 4
Bandwidth, 70 or 100MHz
Battery
Vertical 500uV
Warranty 4-10 year
Storage 28M vs 2.8M
HDMI
Auto Range
Frequency Meter
WLAN
High/Low pass
Carry strap

..And AFAICS not very successfully - the 10" ones seem to have been around a coupel of years with very little profile.  I agree they were aiming too high with what was a new type of product from an unknown manufacturer.
I don't think the extra size has much benefit, and reduces portability.

Re. the battery - I'm pretty sure that a "no battery" one will come with a dummy PCB to pass the incoming supply through to the unit.  As & when the battery dies it probably wouldn't be hard to replace the cells.

If they were to go all-out with the non-M version with decodes at a price similar to comparable desktops they could do really well, as they seem to have done a decent job on it, both software and hardware, probably better than any of the other Chinese manufacturers.

It would be interesting to see if there are any hardware differences between the M and non-M version. Somewhere I saw a reference to an "online" version, maybe suggesting they were going to sell different versions through traditional distributors. I can see some logic in that so distributors aren't undercut by direct sales, but both versions seem to be available on Aliexpress.

I used openssl to decrypt the update package v6.0.186 ( available at this link )
I padded the file and decrypted using openssl with --nopad option and -K 'hexkey' ( without complaining )
But when I run the decripted script it complains that md5 is not correct ( so I modify the md5 stored in the script and everything executes/extracts correctly even if gzip throws an error at the end saying 'unexpected end of file' )
I padded the file adding 8 caracters at the end ( tried 0x00 and 0x08, no joy )
What am I doing wrong?
How to decrypt using gpg?

P.S. now I'm more confortable to update to v6.0.186 knowing not to lose telnet connection

I also purchased a TO1104 with battery from Batronix.
However, my unit came without carrying strap and WLAN option is not activated. 500 uV option is activated though.
There seems to be some inconsistency regarding delivered options…

I would like to have the WLAN option, but Batronix is not selling it at the moment.
Considering the firmware investigation work already done by some forum members, we may not have to wait much for all software options.  >:D
Those BNC dust caps that came with Mike’s scope are also a nice accessory I would gladly purchase, if available.

I also performed some BW tests on my TO1104 using a R&S SM300 to generate a 1 Vrms signal and a 50ohm feed-through terminator and found the -3db point to be near 135 MHz. This result is consistent on all 4 channels.
Although severely attenuating the signal (as expected) the scope is still able to trigger and display a stable 250 MHz sine wave. Above 250 MHz things start to go south very quickly (1 GSa/s plays a big role here…).  :-BROKE

As said before, serial decoding option(s) would be more than welcome.

The UI can surely be improved, but as it is now is surprisingly easy to use and it only takes a few minutes to get used to it – In my opinion, this is a very strong point for a new product so radically different.

Let’s wait and see what Micsig do in the future; So far they seem to be on the right path.

I didn't actually run the script that you get after decrypting, I just asked binwalk to extract the *.tar.gz from it. I think mine might have said "unexpected end of file" but there wasn't anything missing/corrupt so I figured no harm. I used a python script and pycrypto for decrypting.

You mentioned you had the 1074 without the options, so it would be interesting to compare your /firmware/scope/sn115508.dat (this seems to store the options and bandwidth setting) to someone elses with the 1104. Could someone extract theirs? (for science, I had a look at the code that reads/sets the options and I'll look into that further but just as the update files it's super weird..)

Oh I forgot, colour coded BNCs would be nice. I've put labels next to the BNCs. The colour scheme doesn't match what I'm most used to, but then again all manufacturers seem to have their own colour scheme. Not a problem when I'm using it, just a mInor PITA when setting it up, as unlike my bench scopes, which have their probes almost permanently attached, a portable scope doesn't.

I've connected to the scope via microusb and using python-usbtmc sending commands to the scope:
*IDN? -> replay with model, serial, hardware rev
:SYS:SN? -> serial
:PRIV:MACH? -> TO1074
:PRIV:BAND? -> 70
:PRIV:STAT? -> 0

unable to change bandwith and model :-(

other interesting commands ( I think ), found in Desktop executable from addr 0x72f90:
:PRIVate:STARt
:PRIVate:STOP
:PRIVate:STATe
:PRIVate:STRingcode

Tried sending different strings, and start commands, but state do not change

I've looked some more into the Micsig software and particularly the config parts. The result of that is a tool to upgrade the config files of a Micsig TO scope:

https://github.com/stschake/micsig-upgrade

This will enable 100MHz (for the 70MHz models) and among others the 500uV, WLAN, HDMI options. It does require that you can access and change files on the scope over e.g. telnet or FTP, so it might be interesting to package this as a firmware update that can simply be put onto storage.

Re. the battery - I'm pretty sure that a "no battery" one will come with a dummy PCB to pass the incoming supply through to the unit.  As & when the battery dies it probably wouldn't be hard to replace the cells.

Can someone with a non-battery version confirm Mike's theory? Would it be possible to add a battery by simply connecting another tablet battery to a non-battery dummy PCB? I've got several broken tablets with usable batteries.
Yes, I do understand that is not what Mike was saying.
No ( at least not easily) , because the PCB also has the charging circuit and the protection.
It may be that the dummy PCB could be an unpopulated version of the charger PCB ( or maybe even a populated one?). Would be interesting to see, but hard to see why anyone would buy one of these without the battery.

It would be interesting to know what is in the config file of the M versions of the 'scope, since they look to be the same scope but trimmed down specs (2.8Mpts, 20K wfm/s) vs the full version (28Mpts, 80k wfm/s).
Since 2.8Mpts still won't fit into the XC6SLX45 block ram it seems likely the M version still has the memory chips fitted (or at least some memory chips fitted).

A price somewhere between M series and normal price for the 70MHz could give the Rigol 1054Z a real run for it's money once the serial decoders arrive.

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.

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)

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.

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.

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.

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.

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...]

Actually, I think it's positive because it shows that despite initial concerns and cynicism we are open minded enough to stand corrected. I still don't jump for it as a bench scope though, I remain knob centric.  :scared:

Just received my TO1074 from Batronix. It came with the strap and all the options enabled except for 28M storage, including 500 uV and WLAN. It has a "delivery date" of 2016-12-22 and version 7.12.0.212. This version already has the option to record live videos, it creates AVI files encoded with H264 at 800x600 25fps at around 5500kbps. They look fine. The UI has some minor changes compared to mike's video, mainly the channel settings is a dialog now and has a few more options.

Unfortunately it doesn't seem to have telnet enabled. A TCP scan reveals ports 7, 13, 21, 37, 80, 8888, 18211, 18212. Port 8888 outputs large amounts of binary data constantly. It is what the remote control app uses (available on the chinese website, all it does is show the oscilloscope screen on the PC as it is on the device), so it is likely just a video stream. Port 18212 disconnects immediately without sending anything, port 18211 stays connected but also doesn't send anything. It is possible to login to the FTP with the root/micsig user, but it just shows the same files than via USB storage.

It is also possible to install options via a "licence" code, but it seems to be encrypted based on a device specific UID that it seems to get from /sys/devices/platform/cpu/uuid. So far I have not found any way of getting this UID, if it is not possible to obtain it easily the firmware upgrade route may be the only way to unlock it.

@cmpxchg let me know if you want me to test anything :).

Can you confirm it will support all the things that serial decode should do :
Arbitary baudrates ( i.e. not just "standard" rates like  9600,19200 etc.) , up to at least 6Mbaud
Configurable polarity ( idle high or low)
Display in hex, decimal, binary and ASCII
Display of framing errors.
Time-stamped Lister mode

Will there be serial trigger ?

I'd also ordered this TO1104 last year, one thing get me go nuts is their screen film, maybe just because I'm a bit dumpy so I failed to stick it to my scope, and more worse, I only brought one screen film. I just want to know if there's someone help me figure out how to apply it, it's ridiculous they sell that but have no guide of that! I also find they sell TO1104 on amazon and give special offer to North America guy, it seems our Korea guy don't have that special treatment, a bit unhappy so.
Here's the link to prove my words:

No need to dismantle the scope. Just cut the corners of the protection film matching to the shape of the blue corner protection frame and put it on that screen.  ;)

Touch screen and portability are more useful than I thought. I often get in the habit of using the tablet as my main scope until lack of decodes or bandwidth make me boot up the Rigol 4000, at which point I spend the next 30 minutes resenting the Rigol for not having a touch screen and portability.

Faster+longer FFT than Rigol 4000. I wouldn't call it good, because it doesn't have spec. an. controls and capabilities, but it's less bad than most others in the price category, except GW Instek and their speedy Zync FFT :)

More lag when moving/zooming traces than my Rigol 4000, exacerbated by the fact that it's a touchscreen which makes you want to do more moving/zooming   :-\  Also, lack of 50 ohm and probe recognition is slightly annoying.

Ah! A semantic discussion on the meaning of "necessary".   Let me make a pot of coffee.

I just received a TO1104 yesterday and ran a few tests on it. I was worried about the responsiveness of the touch screen after watching Mike's video (great job on the video Mike!), but I think you have fat fingers or something Mike! I found the screen to be very responsive. I won't miss having pots to wear out either!  8)

I did a frequency comparison between a 10Mhz frequency standard (below the scope) and a newly purchased eBay special Berkeley Nucleonics 625A Function Generator. I found the video capture quite useful for sharing as you can see the frequency walk back and forth between the two units. Without the video it would be hard to show someone. I really like that feature. It also gave me an idea how far off my purchase was (10,000,040.80 Hz) Close enough for what I do.

I have a "modified" Rigol DS2072A and I think the quality of this is just as good if not better. Plus the portability will be great for some project I have that need the 4 channels.

Only complain I have is what others have mentioned, which is the serial options. I hope those will be included in an update soon.

I am considering upgrading my DS1052 to 1054, but I would love to have a usable FFT.

I am particularly interested in audio frequencies and harmonics.

I did a FFT with a 5kHz Square Signal (Ch 1)

The first Pic shows the FFT Parameters (dB, retangle)
The red MATH Button shows 10dB/div and a max. Math-Freq. of  500kHz

The second Pic shows the full FFT, and the left/right Cursor Measure (red)

I hope this helps.

Cool, thanks a lot. Any hints on the slope? I could not find anything useful on the manuals. And I do not see an option for bandpass or notch. Can it be done with a combination of high-low? Or is it not supported?

So I've the 'scope for several months now, I'm not a daily user but every few days / week I need to spend a few hours investigating circuits, normally low power chip power supplies, serial lines, clocks etc, typical frequencies range for a few MHz to several 10s of MHz.

What's it like to use...
Quite nice and easy, only needing to clear a small amount of desk space, and not root around for a power cable is great, as is the ability to take it wherever I need it (normally home or work), the thick(~4cm) tablet format  makes it an easy fit in most bags.

The screen is a nice size, interface far more responsive than Rigol, memory depth is good, being able to zoom right in from long serial packets to the fine edge detail on bit boundaries. Normally I only use 2 channels, but the channels 3 & 4 get used to sanity check other signals while I'm decoding i2c, overall still pleased with it as a purchase, and it is my 'goto' quick scope in preference to loaning a Keysight 3034 from someone.
Serial decoding is nice but still a beta feature, very stable though so I imagine it's only a few weeks away from formal release (I needed it a few days ago for a project so I asked the micsig sales team)

I do hit the occasional annoyance:
Less fan noise would be nice, it's only on a par with other lab kit, but louder than the laptop.
Fingerprints on the screen is a little annoying, and need to avoid reflections when placing it, but this is only a minor issue.
FFT is nice and quick, but markings in the frequency axis would be nice, as would be some filtering

As a light / casual 'scope user it still gets a big  thumbs up :-+ , but a daily user might find issues I've not bumped into.
If anyone has any questions feel free to reply / pm.

Can anyone recommend a reasonably snug fitting case for this device, possibly neoprene or similar with a probe pouch? The optional nylon "handbag" seems rather oversized at 30x41x13cm, and I haven't seen any for sale anyway.

My intention is to be able to protect it inside a carry-on or electrical tools bag.

Probably worth a trip to a local market or car boot sale or similar to see if there's something suitable.
I use an old Compaq laptop pouch - laptops are thinner these days so can be hard to find.
As a temporary solution, but without the probe pocket, jiffy bags work!

That is totally not what you want - it's far too bulky.
This is a mistake many manufacturers make when designing cases - they assume that you will carrying only the instrument - fine for the manufacturer's sales reps, but no good for most users.
You will always be carrying other tools, DMM, laptop etc. Different people will havewant to carry different amounts of other stuff so it makes no sense to try designing a case for the instrument + other stuff.

What you need something that :
1) Protects the instrument from damage when put inside a larger bag with other items
2) Keeps all the small accessories ( probes etc.) together with the instrument in a seperate compartment, so they don't get lost when the main compartment is open. 
3) Is absolutely no bigger than necessary to achieve the above.

The end result case-wise for me has been a Logik brand case designed for 11.6" laptops, model number L10LBK11, costing £9.99. It's not quite as padded as I'd like, I'd have preferred neoprene sides, but it does have a pocket that just fits the four probes. It's very snug.

The AC adapter will also fit inside with the scope at the side, but a standard IEC/kettle lead cable wouldn't, but those cables are ubiquitous and robust enough to be thrown in an external carrier.

I have not received it yet so can't comment on how well it fits. Maybe the foam inlay can be 'remodelled'.

That looks good. I've ordered the same case for my debranded Micsig MS220T handheld scope which should fit well also. Thanks for the link.

I sold my companion for years which was my always handy ds1052e and I'm looking for a new one, I'm interested in the TO1104 but the TO1074 is still a really great option I think
The optionals are expensive and the shipping I find on aliexpress is expensive to my country Bolivia, almost as expensive as the unit itself so that is a really turn down
I really need something portable this days so this one really caught my attention but is a really great investment and I ave already made my decision and I'm going to get it if I could find somewhere with a reasonable shipping cost.

I agree. Shipping costs from Europe should be in the US $60 to US$80 range. Ofcourse there will be VAT and import taxes to pay to the Bolivian government.

The TO1102 and TO1104 with battery are available on amazon.com US.  I don't know if you can get items from amazon in Bolivia...

I'm taking a look but I have just found an ebay seller with the name  micsig and they have the to1104 with battery and 60$ shipping to my country which is not that bad I only hope they are not using dhl or fedex because they charge here 40$ extra for "paperwork" for anything could be a 1$ chip or a 1000$ laptop they charge that 40$ anyway so I always try to avoid them I prefer EMS or even regular mail also UPS is not that bad.

that ebay seller seems like new and only has a feedback score of 32 with 97% positive feedback but it is the best option for me so far.

Here is the link to the amazon item: https://www.amazon.com/Micsig-Tablet-Oscilloscope-100MHz-TO1104/dp/B0711CN4SX/ref=sr_1_8?ie=UTF8&qid=1495571315&sr=8-8&keywords=micsig+to1104
that would be really great if they really ship to my country, almost always when I want to order something from amazon I got a message prior payment that shipping to my country is not possible even when on the listing says it is possible but I will check into it thank you.

Why would that be the case? I doubt countries next to eachother charge high import duties because that would hamper regional trade unless the governments are totally ass-backwards.

The trade deals like Mercosur and Andean Community does not apply to individuals and small business.  They are tariff agreements on lists for certain products that can be exchanged between countries, like autoparts, agricultural products, etc.  Ask to any Argentinean if He/She can bring any products from bordering countries without paying custom duties (over US$ 400).  I grew up in Argentina and I know how it used to work.  Or try to explain to Canadians why they have to pay import duties to buy items from the US, if they have NAFTA.

But maybe things changed in the last years and let Jorge explain if what the Peruvian dealer is proposing is even possible... If not, why do you think most of Latin American hobbyists look to buy directly from China or the US and not closer neighboring countries?

As I said in my previous post, it all depends on the final price that Jorge will pay by buying it from Peru or China or the US.

the import duties are the same from neighbor countries or countries in the other side of the world like Australia or china with some exceptions about things that where actually manufactured in the same neighbor countries
on side note also the guy I sold my dso1052e to was about to get an oscilloscope from Peru and was about to pay a very expensive price

and also I prefer most of the time buying directly from china I tried buying from Peru or Argentina before and in the end it happens to be way more expensive mostly because as TK said double import duties and also double shipping cost.
unless the governments are totally ass-backwards.
I am afraid that is the crude reality
yep it actually is

the Rigol DS1052E that I used to have I got it from dealextreme witch was the only one that at the time that would actually ship to my country that's why here is very rare to see some hobbyist or even professionals that actually own an oscilloscope that's why I got a really god price selling my rigol and I already miss it
I was about to buy the TO1104M without battery but I will make a bit of sacrifice and get the 1104 with battery but at the end the taxes are not that much the problem most of the time is the shipping cost and the extra 40$ that DHL and FEDEX charge on top of the actual shipping cost and taxes and many times sellers offer only one of those options and with an average wage for a junior engineer as me of less than 300$ monthly that 40$ is actually a lot.

I really appreciate your help and comments

How user friendly is the cursor operation on the fft result?  Also what is the max fft size achieved? Lot of users commented that the fft is quite primitive. Is it at all useable?

The price difference between the 1074 and 1104 model is alsoquite significant, almost 180E  .. Only difference i can see, apart from the BW, is the mem and lpf/hpf function, how is this justified? Especially when compared to the 35E difference for the 70-100MHz 2CH versions!

Looking at the spec on the Micsig website and in the brochures, etc, it says there are 31 types of auto measurement, but when I look at the photo of the measurement selection screen there are only 23. Which is correct?

that is absolute right, every tool is a real investment even if it is only for hobbyist work because it opens up many doors for learning, working and having fun.

I will buy this by the end of June so I will be saving a bit of extra money.

Regarding to the case for the unit here I have a friend who makes customized cases and bags out of real leather and also other materials really cheap I will ask him to do it for me and see how it ends up.

I try to explain to you, but I am not sure if I can explain clearly. It is highly appreciated other's help.

 In measurement function, there are phase and delay. when you open them, you need to choose the desired channel and desired source, then you will get different setting group.There are 10 types.

So the total is 31 kinds of measurement.

Hey,

In another thread some questions came up about the differences between TO1074 and TO1104. Some of the guys are already testing the firmware which includes serial decoding, but they're doing so on the TO1104, so the question is: will serial decoding be available on TO1074 too?

Another question: is it (or will it be) possible to buy an upgrade for TO1074 to get the specs and features of TO1104?

Hello,
I'm not a good speaker, english is not my native language, sorry in advance, but I'm trying to make a review of 4 oscilloscopes I have for now -
 Micsig TO1104, Rigol 2072A, Tek TDS 744A and Agilent 3014A

1st part, bandwicth and FFT function -


2nd part will be about waveform rate and rs232 decoding (I've got Micsig with beta firmware).

If you have a good ideas what to test, let me know.

Is the beta version of serial decoding shipped with current TO1000 scopes? Any updates on this feature?

I want to buy some low end scope for simple tasks, so I don't have to boot up the 1 GHz one every time. I was thinking either DSOX1102G (well proven serial decoding, but not portable) or TO1104 (serial decoding unknown, but portable and 4CH).

Also, is the TO1074 "upgradable"  (BW, mem) to TO1104 or is it using completely different memory chip?

For now I'll wait for your part 2 video :), as I want to see how responsive the decoding is - I hope it's not like DS1054Z decoding - slow and decodes only screen data.

Unfortunately the decoding isn't fully finished yet so don't expect too much from protocol decoding from the beta version. It works but there are some rough edges and no list view.

part2 of my review -


0:00 - memory depth test
2:28 - waveform / second test
7:22 - runt signal triggering
12:18 - uart decoding and triggering


I've found several bugs in micsig -
1. FFT function becomes flickering red rectangle when input trace is a flat line (disconnect probe, set channel to 1v/div, turn on FFT). You can see in in part1 on 13:08
2. For the FFT trace 2 buttons V / mV must be renamed to something more adequate, because it change dB / division scale. The same is true for horizontal scaling buttons (rename it from "S" "nS" to for example - "MHz" "Hz").
3. There is no way to quickly reset trigger point time offset to zero. When trigger delay is large, I have to zoom out, move trace horizontaly and zoom back in. See 4:40 in part2 Found!

4. UART decoder doesn't correctly set 8bit + parity check bit, it require to set 9bit. Compare Agilent settings and micsig on my video.

Also some wishlist -
- It's not comfortable to see UART decoding in ASCII symbols, and set trigger in HEX. It would be better to use the same (DEC, HEX or ASCII) format in both decoder and trigger setup. Agilent does this. Rigol doesn't.
- UART decoder uses only one channel (unlike Rigol and Agilent - they use 2 channels Rx and Tx in one decoder). So you can't use for example all 4 channels in decoding 2 protocols - I2C (1 and 2 channel) and UART (3 and 4 channel).

So I've ordered TO1074 yesterday - I wonder how long it will take to arrive (Aliexpress Shipping).

From the video it seemed to me that serial decoding (even current beta) is quite usable. DSOX1102G might be superior in that respect, but it is quite a bit more expensive and the portability and 4ch were of more importance for me.

Did you check the specs/options very carefully, many of the ads are quite confusing.

I contacted Batronix.com support to ask about the upgrade possibilities for TO1074. Instead of giving me all the details they've updated their website to show what's available on which version. Sadly, the guy didn't provide me with the pricing and said that I need to contact their sales dept. And he couldn't tell me anything about the decoding feature availability as it's still in development.

https://www.batronix.com/shop/oscilloscopes/Micsig-TO1104.html

What seems strange to me is that according to the updated table, the low/high-pass filtering is available on TO1074, which according to the Micsig's website is not.

Oh, yes it is a mess. Aliexpress system is not bad in general, but I guess it is not suited for this type of sales (multiple products in multiple variants with multiple options). Micsig could work around that by creating multiple listings for each of the base models (i.e. 70MHz-M, 70Mhz, 100Mhz-M, 100-Mhz etc), but some people would find that confusing as well.

I've used this link:
https://www.aliexpress.com/item/Digital-Oscilloscope-100-MHz-4-Channel-Portable-Electronic-Diagnostic-tool-automotive-Digital-car-detector-kit-DIY/32802131492.html
and ordered "TO1074 Optional 1" which I hope means with battery, carry strap and screen protector (I didn't need their bag, I'll get one from PCWorld mentioned here on the forum).

I agree that's what you should get with Option 1. This is how bad the cart description is.

In my opinion the micsig is missing some important features that could easily be implemented in software. Hopefully this will be heard by micsig in order to make their product more competitive against keysight dsox1102g and other sub-1000E oscilloscopes -

1. FFT on the math channel (to e.g. perform FFT on a differential CH1-CH2 meadurement)
2. d/dt math operation (useful for differentiating pulses, if combined with feature 1 ciuld be used for freq response analysis)
3. A more useful display of the fft function by observing R&S hmo and GwInstek implementations.
4. Fft averaging
5. FFT peak hold(useful for those freq sweeps)
6. Boxcar/hires averaging mode
7. Downloading a csv file of the whole 28mpts memory through the web interface

I don't need serial decoding function now but it may be good to have it later. Will it be available for free for existing customers or there will be a charge to add this feature when it officially comes out?

If they allow people to try out the beta version of the decoding, perhaps it might be free? Or they just need beta testers.

The tBook mini is a 2nd generation of tBook. Only the mini has low/high-pass filtering as far as I know.

pls contact Batronix, they will send you the price info. and Micsig can send you the bus decoding upgrade info if you need. But now it is the beta version of  serial bus decoding. .pls email to sales@micsig.com.

As I know until now. the bus decoding function is free to upgrade now.

Micsig kindly sent me a beta of the decode firmware, 6.11.1.245.

I suspect it's operator error, but I can't get the decode bus to display on the screen at all. It does trigger correctly. I've tried both UART and I2C, and I have the same behaviour.

Could anyone enlighten me?

I believe there may be dependency derived from the serial number which I guess determines a hardware dependency, micsig asked me for my serial number and current firmware version before sending me a link to the firmware.

It took them about 3 attempts to send a version that my scope would recognise as a valid update file. They then sent a license key to activate. Don't have it in front of me but it is version 6. something

Check the license key carefully.  I was entering mine and one of the digit looked like the number 1 but it was the letter I, so zoom if possible to a larger font and enter the code in the scope.

I guess they send them your firmware, no code.

The firmware you installed only have bus serial trigger function, and if you need the serial decoding, pls email them you have installed the beta version successfully.

It will be better to post a link to the firmware here on this forum instead of only providing a link to the firmware on request. I know it is still in beta but it is useable.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Hello, my TO1104 has arrived. After charging it for an entire night, I turned it on and entered the password for my wifi at home. Then, from the touch screen, I turned it off. Few hours later, I tried to turn it on but it does not seem to work.

When the power button was in blue and nothing on the screen, I pressed and released the power button quickly. A fully charged battery power symbol appeared briefly on the screen. Then, the screen turned blank. Power button is still in blue. I pressed and released the power button quickly. Again, a fully charged battery power symbol appeared briefly and the screen turned blank. I then pressed the power button for a few seconds and released. Micsig appeared on the screen and a battery charging animation showed up. Then, the screen turned blank. Pressing the power button again. A fully charged battery symbol appeared and the screen turned blank. I disconnected the power cable and pressed the power button. Then, the signals show up. What is happening? Do I have to disconnect the power for the scope to work?

This sounds like a typical android phone/tablet behavior, that it is impossible to turn on while it's charging. I don't know what is running underneath micsig's interface, it may well be a modified android os. If it's anything like android, then it should keep on working after you turn it on and plug the power supply back in.

You can use the scope while the power cable is connected.  Just press the power button once and it should show the battery symbol and then continue waiting until all lights on the right panel blinks and then scope application will start.  I had a similar issue with my unit when I received it and maybe it is the anxiety of using it, but I pressed the power button several times and sometimes it remained off and sometimes it turned on, until I learned that I need to press it just once and wait.

Hello, to test my scope, I connected it to the function. I applied the same signal to each channel in turn. That is, connected the cable from the function generator to channel 1, pressed Auto and chose to measure amplitude and frequency, saved the screenshot. Then, moved on to the rest of the channels. I observed the following:

1. The measured amplitude and frequency are slightly different across the channels. Is this normal?
2. While the horizontal lines of the square wave on Channel 3 are straight and horizontal, those of Channel 4 are slightly tilted. The horizontal lines on Channel 1 are slightly tilted and not straight. In the case of Channel 2, the tilting is very bad. Anybody knows what is going on? Is there something wrong with my scope? I did not make any adjustment on the function generator while I did the testing. Thanks.

What cable are you using from the function generator to the scope?  If you are using the probes, you should compensate them first.

Thanks. Is there a manual which came with the scope? There is none in the box. I also cannot find it under their website:

Please post the link to download the manual. Thanks.

Channel 2 is on AC coupling and your square wave is 50Hz so what you see is normal because 50Hz is way below the minimal AC coupling frequency. Also the amplitude measurements seem OK. Expect an oscilloscope to be 3% accurate at best for amplitudes of signals in the audio frequency range.

When the power adapter is connected you have to press the power button twice. First to wake it up and then to switch it on. There is a short introduction slide show in the TO1000 itself. AFAIK a manual is work in progress.

Let it warm for 30 mins and then run the Self Cal exactly as described in the manual.
Report back.

Thanks. Is there a manual which came with the scope? There is none in the box. I also cannot find it under their website:

http://www.micsig.com/html/list_35.html

Please post the link to download the manual. Thanks.
There is a starter guide in the scope itself.  Press the home button to get access to the manual and other applications.

Is it really? I could not find the AC coupling lower frequency limit in either the manual or the datasheet, but that would surprise me. Usually the lower limit is well below 50 Hz (7 Hz in 1 MOhm mode on a random Tek scope). So much for using AC coupling to measure ripple, then.

Thanks. I know about the "Quick Start Guide" in the scope but is this the manual that tautech referred to? There is no mention about Self Cal in that guide. On p.18, there is a Probe Compensation page but I did not use the probe when I did the test. I just connected a Radio Shack cable from the Kenwood FG-273A function generator to the scope.

The manual in Chinese has 110 pages. I cannot find the English version.
http://www.micsig.com.cn/UploadFiles/Documents/mini/tBook-mini%E8%AF%B4%E6%98%8E%E4%B9%A6.pdf


Just curious, what is the reason for warming it for 30 minutes before doing Self Cal?

AFAIK there is no english manual. Just the starter guide.
If you need some explaination about the general usage of an oscilloscope, you could have a look for some application notes of other companies or manuals from other devices to get a grasp of the basic usage. (Or maybe Micsig support can provide something?  :-//)

There are also some books about "basic oscilloscope training" ...

F&C
I never realised there was no manual for these units, I just imagined it would have been on a CD included in the package. I realise you've just got yours but a rumble through the menus should be able to find the Self Cal.
In Siglents it's in a Utilities menu.
It's standard for ALL test equipment to have been warmed up for a while before any Self Cal or internal adjustments.

Let's say you want to take a precise measurement............do it with a cold instrument, NO WAY.
The internals all need to be at some uniform temp, a temp that has generally been reached after ~30 mins operation. Old Service manuals state the requirement for operating temps to be reached before adjustment or accuracy that can be relied on. Cal Certs also have the temp stated on the cert so that results can be replicated.

Self calibration is called Self Adjust.  Pull down the menu, click Userset, then Self Adjust.  It will show a message "SelfCalibrate is running..."

With a -3dB point at 7Hz you'll start seeing the effects at 70Hz.

I waited for 30 minutes and did the Self Adjust. Here are the results. What do you think? I have the following two observations:

1. It looks like a new issue came out which did not happen before. i.e. some horizontal lines became dotted lines. See the two green lines at the bottom (on channel 4) for example.
2. In Channel 1, the yellow horizontal lines are not very straight.

It is an oscilloscope, not a logic analyzer.  Do not expect to see perfect square waves.  Electronics is art and circuits are made of components that have a wide tolerance range... it is not a perfect world.

You are using an oscilloscope with intensity grading.  The trace areas that are brighter means that signal is being more repetitive in that specific area.  You are looking at a signal being superimposed 800000 (roughly) times a second and that combined signal is what the oscilloscope shows in the LCD at probably around 60 Hz.

Thank you all. Do I need to calibrate the probes as mentioned on p.18 of the guide? Haven't touched them yet. Do I need to perform some tests to make sure that the scope is working fine while it is still under a return period?

I would put it another way. An ideal square wave would require infinite speed of signal (how else it can immediately "jump" from one level to another?). This is of course impossible. That's why the _edge_ is never perfectly vertical. But everything in between edges is totally different story.

So, depending on where you see the distortion (and the type of distortion) it can perfectly normal, can indicate uncompensated probes, bandwidth problems, signal integrity issues, measurement problems (e.g., using 1x probe when 10x is required), or calibration issues.

Yes! Pages 17-19 in the Chinese manual. Use the scope's 1kHz, make sure the probes are on X10,
And then you could swap the probes around to give the best Y amplitude match between the channels, calibrate them again and then colour mark the probes for the channel.

With a -3dB point at 7Hz you'll start seeing the effects at 70Hz.
So what you are saying is that you would not see this effect at 100 Hz, since that is well above 70 Hz?

The attenuation would be about 0.1 dB at 50 Hz. The tilt is due to the phase shift, and that will still stay an issue until something like 1 kHz. So definitely not because 50 Hz is below the knee frequency, but because it is not far enough above it for the phase shift to be negligible.

I have just done it. What do you guys think of the results?

In Channel 1, the horizontal lines are dotted ones rather than solid horizontal. Same as those in Channels 3 and 4.

In Channel 2, the top left of each square wave are cornered. The bottom corner of each square wave seemed ok. However, when I turned the knob of the prob to make the top left corner of each square wave a straight 90 degree angle, the bottom ones became cornered.

In Channel 4, how come I cannot make the top three horizontal straight? They are still wave-like even after Self Cal and probe compensation.

I have the TO1074 version of this scope. I really love the portability factor combined with the very good interface. There have been more chinese scopes ofcourse but they always seem to fail with the interface. Really love it!
I'm still searching for a good bag for it though.. what are you all using? I saw some suggestions earlier in the thread but still not what I'm looking for.

I did finally get the serial decode working, I was confused as I'd assumed that the activation code sent with the link to the firmware was for the decode. It was actually for the 500uV. After I'd confirmed I'd installed the firmware, I was sent a further activation code which enabled the decode.

I've used it on I2C and UART. It seems to work reasonably well despite it being beta. Sometimes doesn't properly decode I2C bytes at certain timebase speeds, by altering the timebase either slower or faster it will properly decode, so I don't think it's due to excessive subsampling. It only decodes what's currently on the screen, and there is no lister/event functionality. The serial trigger functionality seems to be fine so far.

It is useable enough for me to consider this a reasonable option for field use, the serial decode and trigger functionality is pretty much a prerequisite nowadays for my work. The form factor and being battery powered is the icing on the cake.

Hello fellow hackers :)
It looks like telnet is not enabled on new scopes. Has anyone succeed with re-gaining telnet access?

I tried different methods of getting access, but hasn't managed so far. Also, it doesn't want to flash the same firmware twice, nor it allows to downgrade firmware. I tried to bump version in hex editor, but no luck.

One small observation. I unpacked firmware and found telnet is still there, as well startup script. It looks like when Desktop starts (main application) it stops telnet.

PS I flashed beta-version of firmware with serial decoding, looks like scope became less responsive.

AFAIR the firmware files are makeself archives and only do incremental update (move + new files), not the complete update of the Linux directory structure. In the newer firmware telnet seems to be removed from the startup scripts.

I bought NanoPi 2 Fire board, which is the exact same SoC and I'll be experimenting on that first. My idea is to try to boot TO1074 from SD (with my own prepared Linux) or use the USB boot mode (described in the S5P4418 manual). There must be a test point or a 0 ohm jumper on the PCB that would allow to switch the boot order (they had to program the eMMC somehow).

Once the SoC can execute external code (i.e. prepared Linux distro) one should be able to access the eMMC filesystem and enable telnet and so on. I would like to do a complete backup of the eMMC as well. If something like uBoot crashes then Micsig firmware downloads are not going to help.

I still think telnet is just stopped. I think so after analyzing run0.sh (update script) and binaries. But, of course, I cannot reliably confirm this without access.

One more thing, it looks like there is serial with terminal:
Code: [Select]
# /etc/inittab
console::respawn:/sbin/getty -L  console 115200 vt100

Unfortunately, I hesitate tearing down my unit to confirm this (the scope is too lovely and too expensive).

I opened the scope once and poked some test points on the side under the LCD (probing the other side is trickier as the battery has to be plugged in) with the scope but didn't notice any UART.
I would prefer to avoid opening it too many times, as the front bezel is mounted on plastic latches and the LCD is held by screws directly into the plastic - both things might wear out. That's why I got NanoPi 2 Fire for experiments as it is the same SoC, just with more RAM and gigabit ethernet.

Interestingly, on tear down from Mike I see TO1104 equipped 2+1Gb RAM. Meanwhile I see only 256Mb available to the OS (but I may be wrong). Looks like the rest is reserved.

It is (in my TO1074 scope) the K4B1G1646I chip, which is 1Gb and two of them = 2 Gb and that is 256 MB (third chip is for the FPGA). So no difference from Mike's teardown. However, he still got a pimped-up scope as the seller knew who he was. For example, he got 2 speakers and 2 fans, while in mine I have one of each.

OMG, I was pretty sure I have two fans as they are bloody noisy :(. But after your comment I checked and found I only one!

Could someone on next tear down measure fan parameters (like size, voltage and possibly airflow)? I want to replace mine.

I think you're right, they do it just for decrease the noise, for the reason may be a single fan is enough to cool down.

I saw Black Friday promotion has started, TO1104 with battery sells $419 which off $35 and TO1152 put HDMI and decoding function as a gift, but seems not send to Korea, so I go to the Aliexpress store, I saw the same promotion banner:

At Aliexpress, scope can send to Korea, does that mean if my friend buy from Aliexpress can get the promotion gift HDMI and decoding function? I mean, if he purchase TO1152, thanks.  :)

I managed to find a  nice compact bag for the mic Sig tablet oscilloscope..

All assesories fit neatly and it also has shoulder straps and the bag is universal. Very compact bag.

Hi,

for nearly one year I am a owner of a TO1104. Since I am missing a possibility to view pdf (datasheets, schematics) I followed the discussion to get access to the software of the tbook mini. Now I teared down my device to find out.
First I was searching for a way to access the RS232 (TxD) of the SoC but with no luck (unfortunately there are 5 UARTs and of course no access to the inner Balls of the BGA).
Then I examined the eMMC hoping that there is a way to connect a SD-Card instead but with no luck either (BGA you know).
Then I hoped to find a way to switch to USB boot mode, inspired by the post of lukier:

AFAIR the firmware files are makeself archives and only do incremental update (move + new files), not the complete update of the Linux directory structure. In the newer firmware telnet seems to be removed from the startup scripts.

I bought NanoPi 2 Fire board, which is the exact same SoC and I'll be experimenting on that first. My idea is to try to boot TO1074 from SD (with my own prepared Linux) or use the USB boot mode (described in the S5P4418 manual). There must be a test point or a 0 ohm jumper on the PCB that would allow to switch the boot order (they had to program the eMMC somehow).

Once the SoC can execute external code (i.e. prepared Linux distro) one should be able to access the eMMC filesystem and enable telnet and so on. I would like to do a complete backup of the eMMC as well. If something like uBoot crashes then Micsig firmware downloads are not going to help.

To cut a long story short:
Shortening the unpopulated Jumpers J48 and J49 (located near the FPGA? U42) do the job  ;D
I can say this because the USB Descriptor (of the USB near the Power-Plug) changed appropriatly.

The next step will be to actually boot (FriendlyARM?) Linux from USB  :box:

BTW:
Did you know that it is possible to switch on the the tbook mini with disconnected Battery(electronics), i.e. without the Power Switch?
Just connect the power supply and use the internal power-on switch S6!

For example, he got 2 speakers and 2 fans, while in mine I have one of each.

OMG, I was pretty sure I have two fans as they are bloody noisy :(. But after your comment I checked and found I only one!

Could someone on next tear down measure fan parameters (like size, voltage and possibly airflow)? I want to replace mine.


exe, I had a look at the fans because I teared down my tbook mini anyway:
  • Size: 45x45x7,5mm^3
  • MODEL: JDB4507M05
  • DC: 5V 1.1W
  • http://www.jingyangda.com/  (do they also have an English page?)

I just got the TO1104, at first glance it seems pretty nice. I particularly like the adjustable high/low pass filters. But I also have a few gripes:

1. At slow rates, 200msec/div and longer that have real-time screen scroll, the waveform memory drops from 28 Mb  to 280 kb.

2. The lowest end of the low-pass filter is 30 kHz. It would be nice to make it go much lower, even to less than 60 Hz.

The combination of these two aspects make the scope not very good for low-frequency, chart-recorder kind of measurements.

3. No multi-touch support to change scales, would've been nice.

4. Finally, the probes that come with the scope no where have a label 10X on them!

It happens if memory depth is set to Auto. You can select 28Mb from menu.

3. No multi-touch support to change scales, would've been nice.
I think, they deliberately not using multi-touch for that. There are to many objects and controls on the screen for pinch zooming to be useful.

After I saw some good reviews (thanks mikeselectricstuff, AndyP, nctnico, exe) I decided to buy a TO1104.

I can say that the overall oscilloscope quality is realy good. :-+  :)
I did some tests and everything seems to be working properly. I did not trying to use the hdmi connection).

I liked the touch screen and the option for use it with a mouse (very usefull in some cases!).

On the other hand, the probes shipped with the oscilloscope has 200Mhz of bandwidth (P130A). For a oscilloscope with 100Mhz of bandwidth, the probes should be at least 300Mhz to get an accurate measurements aroud the specified bandwidth. :o

I sent some suggestions to micsig to be improved on the oscilloscope software:

- the "Frequency Meter" sometimes doesn't work when the channel is changed.

- There is a bug when for example, the "PK-PK" Measure is selected. I noted it with a sinusoid of 10Mhz (1Vpp). The value of "PK-PK" changes between 992mV, 1,01V and 100mV. The 100mV value should not be displayed.  ???

- It would be good to have an option to change only the background color of the screenshots (files saved as .png) to the white or black.

- In the same way, it would be good to have a fine adjustment of the "Time Base", since it is implemented by software (of course, since if it doesn't charge to much the processor!). I noted that the change between 2ms to the next is 4ms which normally should be 5ms. I don't know why micsig made it.

- Another thing that would be excellent to have, is a package sold separately for a power quality analyzer, to get the harmonic spectrum (in a bar format) and to give the Total Harmonic Distortion. The THD could have an option to manualy select the final harmonic analyzed (like from DC up to 25th harmonic, DC up to 51th and who knows from DC until 100th). It is a very desired functionality! The power analyzer, could be a single-phase analyzer based on the IEEE Std. 1459-2010 to give the power indicators like S (apparent power), P (active power), N (non-active power), PF (power factor), S1 (fundamental apparent power), P1 (fundamental active power), Q1 (fundamental reactive power) and DPF (displacement power factor). Lastly, it would be good to have a switching losses analyzer.  8)

Analysing switching losses is tougher than you'd think.

Anyway due to your message I wanted to see if MicSig might have something new on their website and I noticed they have a new (simple) remote control tool which doesn't need the NI Visa crap. I gave it a try and it seems to work! I think they stream the compressed video over the network and send the mouse click back to the scope. Simple but effective.

There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Hello nctnico, thanks for your reply!

Yep, I know, it is not a simple task.
I have already been made some simulations using Matlab/simulink to do tasks like this and estimating the power losses with converters using IGBTs.

I sayed it because I saw (in the reviews) that the processing power capacity of the to1104 is good. Of course, the bandwidth of 100Mhz will limit the analisys as well the current/voltage probes accuracy/bandwidth is a critical factor (due to signal propagation delays, offsets erros of the voltage/current measurements, noises, attenuations, cable lengths, etc,  not to mention the parasitic elements with the igbt circuit, eg. the gate parasitic capacitance, the performance of the driver used, that if it is not adequate, for example, if it has a slow slew rate of the signal drive, it will increase the turn-off losses, etc) but can be a start point for a low/medium frequency switching losses analyses in some types of converters. Moreover you may need to do some manual measurements of the circuit parameters to get a resonable accuracy in the losses calculation. Additionaly, you should have the semiconductor switch parameters, like turn-on delay time, turn-off delay time, rise time and fall time. Although it can be estimated by the oscilloscope, it is recommended that you enter these parameters (from datasheet) to obtain a more accurately results. Regarding signal noise, the signal average method and the bandwidth limitation may be a good idea in some cases that you need to reduce selectively the frequencies higher than of interest. Finally it is good to remember that the type of load will influence the power losses.

In relation to the NI Visa, I agree with you, its a crap, too large (requiring more than 700MB) and does not make sense to made a small specific software (like micsig scopesuite) that need it.

Well, I am waiting if micsig will answer my suggestions.

Basically, after our discussion, I have to say that the option to change the background color of the screenshots to black/white and the "power quality analyzer" as I described earlier would be enough  :-+. Indeed, the "switching losses analyzer" would be something very specifically.

I'm a bit worried there is no software updates, nor new devices from MicSig. Hope to see both... eventually.

It seems odd that just the 5ms setting is 4ms, there are other screen shots here showing the same.
CML+  That took much longer than I thought it would.

I don't think there is something to fix so there is no reason for an update? BTW it seems MicSig has released a 150MHz 2 channel version.

New features. Like, a standard protocol to communicate with the scope. Or faster UI. Or more settings for, say, UART decoding. I mean, of course it doesn't work worse than it used to be. But some improvements would be nice to have.
