New 12bit 500MHz Micsig scope WITH knobs [Mic-OPI] MHO5004-12bit / MDO5004-8bit

[DaneLaw]

Are Micisig about to come out with this scope, that does give some Tek-vibes.
Would be a welcome turn in my view, as Micsigs all-screen models like ETO & TO or the "Joystick" variant of their quite popular STO-series, were somewhat debatable if that was a turn in the right direction.



Or maybe its just a scope-render for their SigOfit optical fiber isolated prope-line, though I doubt that. 
Any info on this model?

// This Micsig model will be released under an MHO-label for the 12-bit, while the 8-bit will be labeled MDO.. It looks to be a "knobs" variant of their ETO flagship... the same OS & specs, as far as I can tell.

[Fungus]

Who knows, but it looks like it will be specialist/expensive - no standard BNC connectors on the front.

[DaneLaw]

Yeah Fungus, it will sadly not be cheap, it looks to be a revised flagship 
Micsig seems to be somewhat tight about it, but at least it ain't just a render - and is a model under development headed to market.
Micsig refers to it as a "500MHz, 3GS/s scope".. if the 500MHz is entry-model bandwidth, I don't know.

It does seem to have resonated with Micsig, that people prefer knobs, no matter how intuitive & touchy' you make the interface on these dual-purpose scopes (mobility & bench-use)
Both Micsig's relatively new models TO (10") & ETO (14") are completely removed for UI-buttons and their newer revision of "STO" line (8") is based around a 4-way joystick interface - with a somewhat minimalized button-layout (19 buttons & 4 joysticks) quite a bit less, than the quite popular STO-C/E series. with 23 buttons & 7-clickable rotary knobs.

Though' the 500MHz, 3GS/s spec on this new model' seems to match their single-line ETO-flagship model (ETO5004) so it's likely Micsig seeing the light, and making their flagship 14" model [ETO5004] into a model with some buttons & knobs, as the ETO5004 also has these isolated Mic-OPI probe-connectors, and the ETO5004-UI seems to be the same.





My guess is that it's this 14" ETO-flagship model (500MHz, 3GS/s) that is present on the Chinese market, that is now being retrofitted with knobs & button interface, and the specs from the [ETO5004], would likely go a long way in getting an idea of this new model fundamentals.

No standard input connectors is a no go  at start,   they seems fragile ??

will they try to set some standard  like TEK with some of their TDS series active probe / input adapters  etc ....

a single adapter who cost a fortune to get etc ...

He refered to fact that scope seems to not have BNC inputs but some other connector (looks similar to some kind of SMB connector..)
That means that you cannot use anything that uses BNC....

Yes, it was mentioned (by me) a few posts up: https://www.eevblog.com/forum/testgear/new-micsig-scope-with-knobs-(again)/msg4854503/#msg4854503

They might be SMA connectors and work with a cheap SMA to BNC adapter.

OTOH I get the feeling we're not the target demographics for this 'scope. 

[scoper007]

Well, just called Micsig, the ETO (w/o knob) indeed cost a dam: 3K+ USD, the Tek-vibe one should be more expensive, no useful info on new scope were provided though, they did say a BNC adapter will come with standard.
My wallet says GTFOH.

Nice form. 

Let's see how it behaves.

[ebastler]

Looks like the dual function knobs (to control cursors, enter "analog" parameters etc.) are gaining a foothold across scope brands? Introduced by Tektronix, I believe, adopted by Rigol in their DHO series and now used by Micsig as well. Nice -- when integrated well into the touch screen UI, these can save a lot of back-and-forth compared to the single-knob implementation.

[sebyon]

Wonder what the price will be... Those are some bold specifications

[Fungus]

Wonder what the price will be...

If you have to ask, you can't afford it.

Probably not but a man can dream.

[electr_peter]

I hope that this flagship model signals that Micsig will produce more lower-mid end (semi-)portable scopes with knobs. STO1000C/E interface with more knobs is much better than STO1000 series (which have "fake knobs" (joysticks) and overall downgrade in UI). I prefer models with knobs rather than touch screen only models and think Micsig can still hold market niche with such scopes.

[MustardMan]

It looks like this thing has finally materialised... I've been waiting since I first saw it on their website about 12 months back.

When they dropped the knobs from the STO I was *so* disappointed. Micsig seemed to be going the same direction as everyone else with dicky pushbuttons. Thank God they've brought them back!

I was lucky enough to be able to purchase a Tektronix "2 series" scope (through work - far too expensive otherwise). The first portable scope since the Tek CRT "222" model that had proper knobs. Their "2 series" advertising: "user feedback and surveys indicated that the number one user request was... knobs". Well, no surprise there.

So, the "2 series" has knobs... but the UI is clunky. The pushbuttons (membrane type) are *absolutely* horrible to use. Sold as a 'portable' scope, but you need to buy an 'optional extra' battery pack to make it portable! And the serial decoding options cost extra, and a non-trivial amount at that (typical of Tek).

The STO1104 (and brethren) are a delight to use, but the bandwidth is a bit lacking, and the UI could be a little better (still far easier then the Tek though).

In Australia the price (for the MHO 12 bit, if purchased through Amazon) is about $8.5k, which is far better than the Tek (and the MicSig is a nicer looking unit). The Tek is quite "fat". Even fatter with the 'optional extra' battery pack fitted.

Sadly $8.5k is too much for me this FY... but next FY I hope they are still around! I'll certainly be getting one.

As for the probe interface... I heard that as the BW gets higher BNCs don't cut it for linearity. Could be all crap because BNCs work fine for RF. Maybe DC to 500M shows problems? And getting passive probes to go to 500M does require effort anyway.

Anyway, to quell your fears, their product brochure lists, as part of the standard package (ie: they are not an optional extra) adapters that fit onto the probe interfaces to adapt to BNC.

Adapters are listed as accessories to connect normal BNC plugs, good.
What I find funny is that micsig recently buried the CP current clamps with their own interface and only the ones with the BNC connection are still in the program....

I find strategic decisions of Micsig very confusing in last few years...

You are referring to the UPI-interface?
I reckon it was more or less an attempt to make an open universal probe standard, that Micsig had hoped other vendors would adopt. (UPI = Universal Probe Interface)

It didn't seem to unfold, and operating with two proprietary modern probe interfaces (UPI alongside their Mic-OPI) would be too much.
Seemed they dropped the UPI standard - and went with OG native BNC for lower-end devices, and their Mic-OPI for higher-end models.

Micsig seems to put a lot of effort into highlighting that Mic-OPI is patented & trademarked five ways to Sunday, I don't recall that on the UPI, and why I speculate that their UPI/Universal Probe Interface perhaps was intended for other vendors to jump on board.

Though, I haven't tried either.
The Mic-OPI is used on their SigOFIT optical fiber isolated probes (DC - 1GHz) and intended for MHO & MDO-line, alongside the ETO-oscilloscope ( all screen 14" no knobs) which so far only seen daylight in China.

[MustardMan]

The Mic-OPI is used on their SigOFIT optical fiber isolated probes ...

All excepting one of the pictures in the brochures show the SigOFITs with a BNC and only one picture shows a SigOFIT plugged directly into an MHO 'scope.

Inconsistent and of concern, so I checked one out and it does indeed have a BNC. Perhaps (if you are keen and have a MHO) you could get one with the custom interface?

But why - it would simply tie an expensive probe to a very specific 'scope.

Cheers, MM.

According to datasheet, the "The Mic-OPI™ probe interface can proceed automatic probe compensation and calibration, also comes standard with BNC adapter to connect with all BNC probes." which is good. It has 1M and 50Ohm listed, which is excellent. It's Android based. The probe interface seems to be some RF connector with a USB Type-C which sounds smart, it would be even better with BNC but I think it's a good compromise.
I like the looks of this scope. These 8 and 10" small resolution screens from others are a bit dated, when you can buy a tablet from Amazon themselves for 35 dollar with full hd screen.

[electr_peter]

This shop sells MHO5004 12-bit for ~3200EUR without VAT. Price is 2-4x higher than cheaper MicSig models - they are looking at higher end market segment than before with this unit.

4 probes and 4 BNC adapters are included.

Kit contains

• Oscilloscope
• 4 x Passive probe
• 4 x MSP-BNC Adapter
• Charger
• Power cord

Batronix added new range of Micsigs - MDO2504/3504/5004 (8-bit) and MHO3-2504/3504/5004 (12-bit). There is also ETO3504/5004 range (with battery inside, 8-bit, only touch with no knobs).
Price range is 2 - 5k€ with VAT (1.7 - 4k€ without VAT).

One thing to note is that new models are much bigger with 14 inch screens (previously 8-10 inch).

Prices without VAT:
MDO2504 8 bit 250MHz 3GSPS 1700 EUR
MDO3504 8 bit 350MHz 3GSPS 2400 EUR
MDO5004 8 bit 500MHz 3GSPS 2400 EUR
MHO2504 12 bit 250MHz 3GSPS 2000 EUR
MDO3504 12 bit 350MHz 3GSPS 3000 EUR
MDO5004 12 bit 500MHz 3GSPS 4000 EUR

The 12 bit overhead is 300 EUR. It would be interesting to see what's inside, I think it's likely they have the same hardware inside, or maybe it's an ADC swapped to 8 bit version of the same part. No rubbish 2 channel versions, but also no AWG or LA. Oh and no 70 and 100MHz entry level model crippled in SW.

[Antonio90]

The base model's page is already available at Batronix.
English datasheet available under "downloads", too big to attach without compressing. It doesn't seem to include the number of math channels, although it has a healthy amount of math with editor, dual 3GS/s ADCs, 360Mpts per ADC, statistics... Only 360Kpts FFT though, even the old, entry level GDS-1054B has 1Mpts. I guess Micsig never cared much about the function anyway.

Micsig is not heavy on analytic stuff on any of its scopes. AFAICT it has only one Math channel.
They are not targeting that market it seems. It seems to be nice, big screen, fancy looking, ultra thin form factor simple scope.
I hope they integrated segmented mode and decoding well.

They are targeting Tek MSO2x series users...

I personally think it is a bit too expensive for what it is. But that is not a problem. Market will sort that out, so either price will drop or I will be proven wrong.
It might as well be that there is huge market for these.. TIme will tell.

Anyways, good to see they are developing new stuff.

I really wish they added bode plotting functionality to their scope. Besides the usual scope functions, the bode plot function built into the Siglent scopes is probably the most important feature to me. Even then I still find the Siglent implementation quite limiting, and wish they improved it further. Almost all scope manufactures in the industry seems to have added bode plotting to their scopes as well.

But given that Micsig scopes do not have built-in AWGs and they don't manufacture external AWGs, I don't think we will ever see bode plotting functions in the scopes they have released thus far. This is a deal breaker for me, and is a shame given their focus seems to be power electronics, and bode plotting is such an useful feature in these applications.

No' sadly not.. MHO3-series (12bit) and also MDO-xxxx (8bit) are not battery-founded, you need the ETO-series (8bit) for an inbuilt battery.
MHO & MDO are very sleek 3½ cm and a massive 14" touchscreen (1920x1200 TFT LCD)

At around 4.3kg, they likely saw it as a tad too big for a mobile battery-based scope. but then again the ETO is the same 14" screensize (3.6kg) and that unit has a battery.
I would have preferred a battery in MHO3/MDO now that Micsig is finally indulging us with knobs again, not least with that native stand which would make it easy to move around in certain environments..
- when you can just take the scope' and place it around a given workpiece or desk, though a high-wattage power bank could also help with that scenario, but it looks like it's running 24v.

on that unit, its the same Android OS (I reckon) so for wireless yoi just open up your wifi like on a tablet and then you look up your WLAN IP and connect to that or download their APK (Android) IPA (iOS) or EXE (Windows) if you wanna control it remotely..
Or you can go into the scopes own rudimentary app store and install the app you want..depending on what you wanna do.
If it simply pictures and videos.. and getting wireless access to your scopes rootfolders.. Android FTP app.. works well. (I would guess it also on this scope as it seem to be build on Micsig's Android GUI)

Yeah, my bad - it do seem like it's not built-in from scratch like previous Micsig versions, their MHO3 manual refers to plug-in < Wifi USB module. (not sure if any somewhat modern Android WIFI dongle will do?)

Weird decision from Micsig, as their MHO3 manual do explain about portable WLAN hotspot, tethering etc.. all things I also recall also are on the older Micsig scopes.
so without a dongle atm, seems to rely on LAN cable.

Hello,

slowly I like the MHO3-2504 more and more. If Micsig and Siglent were to build a device with the best of both together, others would have to dress very warmly.

Hello,

After several unsuccessful attempts, I managed to connect to the PC via USB-C. Not every cable and not every port will work. But as they say in Germany: "Duck good all good"

How do you exactly make that screenshot? as it almost got a low degraded thumbnail grading.

I cant forget that the MHO3 doesn't got WIFI built in from scratch    and you need to rely on some "WIFI USB module" that the manual doesn't specify, from where.
Weird decision in my book, when you have in mind, Micsig's whole portfolio of wireless apps & use cases and how much the MHO3 manual highlight many of these wireless things you can do with this scope..
sure' it's likely copypasted from older Micsig models, as it's clearly the same fundamental Micsig GUI.

Obviously a reason, maybe they expect to sell users that accessory or you can constantly keep the WLAN protocols up to date by purchasing new modern WLAN USB dongle, but no no no.. they could do both. (pluggable + built-in) as its only a scope, very limited what WLAN speeds you actually need.

I would love to see some real life pictures of the unit, with that massive 1200p 14" screen and the 3½ cm thinness on its stand...
Could imagine it would look a little like an oscilloscope-pendant to these  all-screen PCs like Surface Studio2 or Apples Imac.

[egonotto]

Hello,

Yes, the MHO3 looks impressive and is quite heavy. My problem with it is that I have no room for it. It's very wobbly at the moment. The screen is bigger and has a higher resolution than the R&S MXO4. It's a real shame that it doesn't have WLAN. I tried a very old USB WLAN adapter, but there was no response.

PS: I took the screenshot from the PC program (there is a button for this). this is convenient and the file is saved to my ramdisk.

Aha, I see - so it's Micsig's "Remote Display" exe app, that your screen dumping from, and in lack of WLAN you'r simply connecting with a USB cable.
If that is the case, and its also the resolution you're getting on Remote Display, then it's quite telling about the very crude attempt (sofar) to implement this MHO3 into that software, and likely running the same low feed as the case with lower res Micsig scopes' when they connect through WLAN.

I know it's early days for this series, and I shouldn't be too critical, and not many would turn to a remote display approach with such a massive gorgeous 1200p 14" screen and if they wanted a remote display - it would likely be trough HDMI/video-out to circumvent that degraded feed.

Are the MHO3 options built in from scratch.? (ref. attached screen-dump from the manual)
Micsig tends to do that, at least to an extent since 2019.. on my unit, it was 429/1553B that was labeled as not installed, but I haven't checked those in practice.

[egonotto]

Hello,

 ARINC-429, MIL-STD-1553B are not installed.

Although the spec sheet says:
Standard decodes: RS-232/422/485/UART, CAN, CAN FD,
LIN, SPI, I²C, ARINC-429, MIL-STD-1553B

But I can choose it.

The Software is from 17.8.2023

Hello,

if decoding with segmented memory would still be possible and they would add HIRES and maybe WLAN as a luxury on top, then that would be a great device.

[scoper007]

Send Micsig message, give them your SN for the MHO 3, they'll provide the 429 and 1553B for free, just like I got for my MHO3-5005. Cheeeeers.

[radiolistener]

I wonder, is it possible to implement SDR radio firmware for this oscilloscope, it already has high performance RF frontend, processing FPGA and display...

Hello,

thanks. I haven't contacted Micsig yet, because 429 and 1553B are still selectable. You can turn on these decoders. I just couldn't test further due to a lack of signal.

If you activate a decoder and use segmented memory, are the individual segments decoded on your device?

With SPI, the segments on my MHO3-2504 are not decoded.

Do you still have video ability on MHO3 / hopefully in 1200p?
On the older Micsigs, it's on the main screen desktop, where you roll down the menu like it's a standard fx Samsung Android tablet, and there you got video or picture symbol and then a little timer, up in the right corner will count the time, and when you wanna stop recording your waveforms etc, you just click that small timer info-symbol up left, and you don't have to go out to the main menu..

I didn't encounter any external storage limits when I checked it a year or two back, I could connect gen4 NVMe 2TB drives and all 2TB were shown on the scope as accessible. (STOxxxxC/E)
Just as long I had the NVMe drive in a TypeC to NVMe enclosure, it would obviously not run under NVMe speed protocols, but that goes without saying for an external NVMe drive through the scopes USB socket, but it worked fine as an external storage drive at reduced speed.

[egonotto]

Hello,

Unfortunately, I can't send the files from a plugged-in USB drive to the PC via FTP using the ES Explorer.

Which apps do the MHO3 have in the app store.?
Likely the basic app programs like "Office" so you can work the data (CSV) in fx Excel, Word on the scope itself, there also seems to be ES-Filexplorer, and OTA -upgrade app, and this electronic interactive app for various measurements & calculation formulas, that Migsig tends to put on their scopes, but wonder if there is anything added specific to the MHO3?.

[egonotto]

Hello,

There are only four apps in the AppMarket. But you could probably install apps from the local memory or a USB disk. It would be practical to have an app that can exchange files with the PC and also recognize inserted USB disks.
I can't manage to copy files between the local memory and the USB disk.
It would be nice if the PC software could copy wave files directly to the PC.
I was also unable to put the MHO3 into developer mode.

Hello,

ch1 is 1 mV/div and the FFT is from ch1.

Why is it Ch1 V/div settings are not clearly displayed in a tab and you need state them ?

Each to their own but I only need glance at the V/div setting and mostly do the maths in my head for signal amplitude like we all did in the old days with CRO's without measurements.

So must we engage a channel measurement to know what the signal amplitude is ?

[egonotto]

Hello,

there is a band on the right-hand side which also contains the channel settings. However, not everything can be displayed at the same time. My selection in the picture was clumsy. I had only taken the picture for myself and only recently had the idea to post it. In the picture "1 V 10 MHz bandwidth open input.jpg" you can see which information is usually in the right band.

V/div and s/div must always be visible and never hidden or in menus IMHO.
This would exclude any DSO from possible selection in my world.

If its the serial right side banner, then its just the arrow down below to get the native ch info banner.

For a modern dedicated bench oscilloscope with 12-bit vertical resolution, I find screen size & resolution very important, as that is my info-canvas and I don't wanna be undermined by something as  fundamental as the screen.
- can you work on a small screen with low resolution' - of course, works okay, as we have seen for decades.

I understand on a mobile handheld scope that there are limits on how big you can make the screen without making it cumbersome to move around and hold one-handed, but on a bench oscilloscope where size is relative..
nope, make the screen big, and put a big gorgeous high-resolution screen of good quality in it.! (that is so fundamental in a modern 2024 oscilloscope, not least when you get up in a certain pricelevel)

1920x1200p = above 2.3mio pixels at 14" (MHO3/MDO/ETO series)
1024x600 = a tad over 600k pixels at 10".. On a high-resolution benchscope, then at least suit it up with a matching big "high-resolution" screen.

On MHO3 I believe that screen is actually a 16:10 ratio, so you get even more vertical screen, vs a 16:9 for those precious vertical bits., which is definitely a plus.

The MHO3 Micsig GUI looks (for a good part) to be the same as previous Micsig models, just with some added bells & whistles (that IMO was long overdue) and obviously way higher resolution, as my battery-unit are 600p 8" screen and a fraction of the 1200p, as on MHO3
It's a UI that is based around a touch interface, - and then later they added knobs, the majority of Micsig oscilloscopes are without knobs, its only STOxxxxC/E and MHO3 & MDO line, that got knobs as far as I remember.

And one of the big hurdles (IMO, at least in previous Micsig models) I reckon Its a shame that Micsig didn't optimize more of their features for knobs & button interface..- on my unit there are 7x clickable potentiometer knobs - and 23 buttons incl. a shift-button that will open up for secondary features for each of these, so you have a lot of tools to work with if Micsig actually optimized for it.
I would have loved if one of the knobs was dedicated to intensity or heatmap or the variable filters, fx through the lightable shift-button.

An example of the UI on the older 8" STOxxxC/E  (I really like the variable bw-filtering, which goes from full bw down to 30KHz on my unit, with 1k Hz intervals,and where it seems to go down to as low as 30Hz on MHO3)

BW filt 3.18

Hello,

here are new noise measurements.

What is your peak waveform update rate on the MHO3, just in normal auto-memory-mode, where the scope controls the 360Mpts
I don't think Micsig operates with these elevated waveform update seq modes, as we see from some vendors, like fx DHO series from Rigol, where the promoted values, reflect a severely handicapped mode while in practice it was more like 1/20 that Dave was getting.

Im familiar with the official tolerances, but Micsig often put these quite conservative

[egonotto]

Hello,

it is 8.1 Hz with 360 MS
and 40 Hz with 10 ns/div and 1.8 kS
50 kHz with segmented memory 1 ns/div and 1.8 kS and 10000 segments.
But the intervals between individual trigger points are sometimes only about 1.1 us.

Best regards
egonotto

[DaneLaw]

If I recall correctly the spec sheet claims 230.000  wfm/s for the MHO3 with its 360mpts.  (in auto mem-mode??) though obviously peak, with a relatively fast timebase like 50ns and will vary greatly from timebase to timebase

Hello,

what I still don't understand is why they use a Mic-OPI™ probe interface for the Aux Out.
It makes no sense to me. I don't know of any other oscilloscopes that use a probe interface for their outputs.

Hello,

I can only achieve the 230,000 wfms/s in segmented mode. Otherwise maximum 40 wfms/s.

It looks like there are still errors. I also cannot change the brightness of the waveform.

Hello,

with the new update, I am now achieving around 35 kwfms/s. But in bursts.
Now I can change the brightness of the waveform.
