Looks to be using a UI resamplance of Micsig's other MHO models. (MHO3 & MHO6)
So I would guess, you do have statistics and all that jazz.
Screen ratio also matches 16:10  (1280x800)

[electr_peter]

Looks to be using the same UI as Micsig's other MHO models. (MHO3 & MHO8)
So I would guess, you do have statistics and all that jazz.

Hopefully segmented memory, statistics and fine vertical control are implemented.

Knobs are back (much better than joysticks), great
Inputs are standard BNCs without proprietary connections, great 
4.5 digit DMM with 4 banana sockets, 2 fused ranges, CAT I/II rated, SW is well integrated with big screen - can be useful

MHO1 sounds very promising. It is like an upgraded STO1000C/E series.

"Deep Storage, Standard Segmented Storage

Standard segmented storage divides limited storage space into multiple small segments, gathering multiple trigger events within a single storage space. With convenient analysis and viewing functions, it allows for both integrated and individual display, making analysis and positioning more accurate and efficient, turning "finding a needle in a haystack" into a possibility."

Looks nice!

No pricing yet though...

This was just released on youtube:

I asked my local distributor about this scope, and he said this model would come to Europe "very soon", but details about date and price were unknown. He thought that this could become a very popular scope if price and performance is ok. Micsig is a bit of a higher risk scope - less volume, less support, less general maturity - compared to Siglent. So, im keeping my eye out for this one, because i like the concept of mobility, proper knobs, and big screen. But im also aware that one of the newer Siglent HD scopes might be a safer choice.

Hello,

I have had a very good experience with the support from Micsig.
When I entered a license for my MHO3, the frequency was set to 0 MHz. As a result, the filters no longer worked.
I asked Micsig for help, which they gave me. After a few days they solved the problem and gave me a license for a higher bandwidth.

Best regards

Good to hear they are responsive to online support.
What my distributor was talking about is more related to hardware support. Siglent apparently has a support center located in the EU, while Micsig does not (or so i assume). Might make it a bit more time consuming if a device needs repair or service.

Anyway,i still like to see reviews and teardowns of this unit. From what i can tell from the short intro video it seems to be quite responsive on the UI.     

[S13]

Looks like we need to wait a little longer... My local distributor told me they dont expect to see them in the next couple of weeks.
Hopefully Micsig uses the time to iron out all the bugs that come inherently with a new design.

[DaneLaw]

As far as I can tell, it's also not yet for sale on the domestic Chinese market, but the MHO1-datasheet (CN) has popped up..
From Chinese, as still not available on Micsig com.

*Attached.

Thanks for the datasheet! Interesting to read some of the specs.

My impressions are that it has a lot of nice features, hopefully properly implemented, but it is perhaps lacking a bit on capture performance? Single 1GSa/s ADC and 50.000 waves/s update rate. That makes it perform about half as fast as the old Siglent SDS1x04X-E (dual 1GSa/s ADCs, 120.000waves/s). So maybe that comparison is a bit unfair, the MHO1 is targeted more at field work (hence the battery) where capture performance is perhaps slightly less important. And of course it does have 12bit, bigger screen with touch, so that is a true step up from the Siglent.

So yeah... im not sure that with these specs it would replace my SDS1104X-E, but it sure as hell would outperform my Owon HDS2102S in every possible aspect. Well... except for the function generator output.
I wonder if Micsig has a function generator integration option, so you can get things like bode plots. The newer siglent HD scopes really do shine in that department it seems.

I don't know what your Siglent SDS1104X-E actually performs and what is real-world vs specifications.
Many vendors tend to spec-race, many of these criteria for sale incentives.

I recall Rigol's entry listings DHO800&900 are often listed with 1.000.000 wfps and some buyers take that on face value as the scopes norm, from third-party sale listings that are quite silent about the ltd circumstances some of these specs are achieved under, while in actual use and in "normal auto-memory" (where the specs claim 50k) it seems to peak at around 27 to 28k.. at least the impression I get from Daves video, maybe that value has increased with later fw..
https://youtu.be/S8jrpCoZyx8?si=RxRWCflm2w2qeWwB&t=1389
There is a notation inserted at 23:53 with a Siglent 1104X-E and 17k wfps as a compare reference' but I don't know how Dave tested it on that model, and if there are model or fw variables that will fluke that number, and if Silent got fixed memory selection or Auto, and to what extent their sequence vs normal operate.

There is a lot of wrong info going around.. and certainly also on Micsig.
Even a somewhat decent sized salevendor like Batronix.

Will highlight on the older STO-C model.

The Micsig STO1104C Plus has a refresh rate of up to 250.000 wfms/s, enabling users to capture instantaneous signals, as well as abnormal signals more quickly.

While their own specs just below on the exact same model STO1104C says 80.000 wfms..
In practise and while your in auto-memory mode.. STO1104C peaks around 100k (around 98.000 If I recall correct) which certainly wasn't bad for a handheld unit at the time in that pricebracket.

So the best thing is usually to either test it yourself, or get someone else that got it, to check specific specifications that fx matters a lot to you.

Hello,

but with VAT, the Micsig MHO68-350 only costs €9,518.81 at eVision

This is the only case where you can be happy about the VAT.

There is certainly some weird satisfaction in flipping that otherwise heavy TAX switch and visualizing a -32% price reduction.

Hello,

of course this is a mistake. Some time ago, the Micsig MHO68-350 cost € 7999 excluding VAT. They still have this price somewhere in their memory. Before that, it cost €5999 excluding VAT for a while.
However, this error has long gone unnoticed.

Yep, done by all every since earliest DSO days.

Understand that most DSO's work in 2 triggering modes, Sequential and normal use.
Sequential is with minimal blind time and limited to a # of continuous display captures, dependant on DSO settings.

Both modes are dependant on settings which are different for every model and brand and the max WFPS spec claimed is always best case.
Add in Normal or Single and use of all the settings that provide best WFPS and you have your answer to any DSO's peak ability to capture some event.

Preparing a full table to quantify best WFPS settings is a considerable task.......

I dont care what they have done, since the early days.. - not always in the consumer's interests in the pursuit of transparency & making buying decisions in 2025 but would expect that a given product at least can perform up to its merits.

I don't have any of these scopes that Dave refers to [Siglent 1104X-E and DHO804] but since you say "its just the best-case scenario" in regards to the specifications.
Im curious do Dave in the linked example ..use the wrong tactic, to get readings that are so far from the specs.??

[nctnico]

Waveforms/second is the least interesting specification of an oscilloscope. And yet manufacturers seem to be caught up in a arms race to beat the other 

Maybe the managers who decide (you know why people become managers....) just need a big number to pull the trigger on.

Yup, big time wrong methodology.

Every DSO has its settings sweet spot to deliver best WFPS that manufactures use in datasheets.

How dare he, that bugger..
He is gonna risk popping make-believe balloons around the globe.

Checked Rigol's DHO800 datasheet and it seems its 30.000.. the 50.000 I remembered was in fact for the DHO4000, so Daves 27 to 28k is pretty close to the stated 30k, and likely the same approach used on the measurement of 17k of his 1104X-E.

Looks like Micsig.. uses these two videos for both bandwidth & waveform capture rate.

Try it yourself.
Trig Out won't tell the full story plainly as it's designed for sync to a trigger event and comes in bursts which must be analyzed with cursors to reveal the actual trigger rearm frequency.
Now examine at all timebases and with single and multiple channels engaged and the complex picture gets revealed.
Memory depth has an impact too as do the memory management techniques used in DSO's.

Waveforms/second is the least interesting specification of an oscilloscope. And yet manufacturers seem to be caught up in a arms race to beat the other 

I brought it up because even according to their own metric, it is a step backwards from their older STO series (130.000 waves/sec). I had assumed the MHO1 was supposed to be a step up from that (higher resolution, bigger battery etc, "next gen"), but maybe its not?
I agree that waves/sec is not as important as it sounds, probably having good trigger capabilities to detect that once in a lifetime runt pulse or whatever, is more important.

But still, i kind of use it to estimate the performance of a scope. Since waves/sec is sort of inversely related to the dead time of the scope (the part where it has to do the processing, measuring, etc), it kind of gives a sense of the processing power. So in that sense it can be helpful. But maybe we need some objective numbers here, and not whatever numbers a marketing department comes up with...

Why are you comparing it to STO1104C ?
STO1104C had only 28MPts of memory, for instance. Claimed Wfms/s could be achieved only in special settings.

Also I don't see this scope as a replacement for STO1104C. That would be new versions STO1004 and STO2002.

MHO1 , I think, is Micsig reimagining of the scopemeter concept in tablet form factor. Micsig did have (once upon a time) classic scopemeters but they stopped producing them.
It seems they are returning that type of product but in tablet form.
We will see how well it works.

I used both my STO1104C in field, and for years had used original Scopemeter..

I must say that while tablet scope is portable and usable, Scopemeter form factor feels more appropriate (for the lack of the better word) for the more "in the field" work.
Tablet scopes are more of a scope you can take to different office today. Scopemeter is more of a "take it to see generator in the field".

So like with many new products they released in last year or a two, I really don't understand what market they are aimed for...

I actually was comparing it to the STO1004, which has the 130.000w/s, and is specified as their "GEN 4". Tbh, i dont know how long that has been on the market, but since with the MHO1 we are at "GEN 6" i assume it has been out for quite some time now.
