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 ...

It uses fiber-optic probes, completely isolated.

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.

Dug this up on taobao/tmall/whatever: it's about $3500 + shipping.

Pictures of Micsig's new 12-bit MHO-5004 & 8-bit MDO-5004 500MHz/3GSas Oscilloscope with MicOPI probe socket-interface.
Very slim profile just a tad over 3½ cm and a decent size 14.1" full HD screen (1200p) with a back that can be mounted on a suspension desk/wall-arm, 1ns pr div - 50'Ohm.
Looks like the hardware digital L/H filtering is now able to go down to 30Hz and up to full bandwidth filter-control [while on the STOxxxC/E it was min 30kHz with a 1KHz interval to the full rated bandwidth] 
MHO5004 = 12 bit
MDO5004 = 8 bit

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.

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.

I just checked the price for those, and I want to cry . One "cheapest" costs more than all my lab equipment.

A price estimate.
Micsig's official Chinese store lists these 3½ cm thin 14" designer scopes for.

29.860CNY  [MHO5004 - 12Bit - 500Mhz - 3Gsa/s - 360M] ∼ 4200US

15.860CNY  [MDO5004 -  8Bit - 500Mhz - 3Gsa/s - 360M]  ∼ 2200US

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.

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
