content: 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.

content: Yeah Fungus, it will sadly not be cheap, it looks to be a revised flagshipMicsig 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.https://tinyurl.com/c22uaaay/https://tinyurl.com/mw34x8u5Though' 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  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 , would likely go a long way in getting an idea of this new model fundamentals.Linkhttps://www.micsig.com.cn/ETO/Promosheet [CN-pdf]https://tinyurl.com/56274jhh

content: 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.

content: 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.

content: 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 -fartoo 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.MM.

content: Quote from: Martin72 on December 24, 2023, 04:45:27 pmYou 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.SigOFITSheethttps://www.micsig.com/uploads/SigOFITprobedatasheetV2.2_1701411402.pdfBrochurehttps://www.micsig.com/uploads/MicsigSigOFITprobebrochure2023V2.1_1701411421.pdfManualhttps://www.micsig.com/uploads/SigOFIT%20optical-fiber%20isolated%20probe%20User%20Manual.pdf

content: QuoteAll 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.

content: 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.

Only 360Kpts FFT though, even the old, entry level GDS-1054B has 1Mpts. I guess Micsig never cared much about the function anyway.https://www.batronix.com/shop/oscilloscopes/Micsig-MHO3-2504.html

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.

content: 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.

(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.

content: 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 MHO3It'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

When I use this software (similar to a web server with other scopes), the MHO3 crashes from time to time. However, the MHO3 has never crashed when I have not connected it to the PC software.I tried various settings for the XY display and then used the best one. I set a low-pass filter at 200 kHz so that the lines are not too noisy. The signals came from the two wave generators of an Analog Discovery 2. The Analog Discovery 2 has a better XY display.The waveform update rate used to be less than 40 wfms/s.I contacted Micsig and a few days later they updated the firmware and I am now getting about 35 kwfms/s. These are faster bursts with a long pause.My impression is that the MHO3 is not yet fully developed, but that Micsig is very helpful.Best regardsegonottoPS: My MHO3 has about 24 GB of memory free from the built-in 32 GB.

content: Have you asked them about their firmware crashing when used with their software? Odd these wouldn't play well together.I think we are talking about two different things for the X-Y plots. I am more concerned with how slow the screen appears to be updating, not how fast the scope is able to collect the data. Some of those Siglents appear very fast. I was hoping when Dave had posted about a standard method, he would have pulled out that high speed camera they sent him for a review and put it to use. My old scope presents new data to the LCD at about 30Hz. Even if I do nothing else (math all off) and capture only 20 data points, its still 30Hz. Not good but your scope looks much slower which is why I wondered about the memory depth.So, is your case plastic or metal as you thought?

You have to use the USB-C socket and you need a suitable cable, which is not supplied. And many cables do not work.I don't understand why the trigger out doesn't have a BNC socket.When I entered a license code, the bandwidth of my device was set to 0 MHz. This meant that the filters no longer worked. The bandwidth of my device was over 500 MHz and interference signals could be seen in the 1 mv/div range.I then contacted Micsig by e-mail. Micsig was very helpful and friendly. They were able to solve the problem by giving me a new firmware version and a new bandwidth license.Therefore, I suspect that the hardware of the devices is the same, and the bandwidth is set by software.I then criticized the update rate and Micsig created a new firmware version with a much better update rate.The PC software is not yet made for the MHO3. When I connect the MHO3 to the PC software, the MHO3 sometimes crashes. The PC software also crashes sometimes. However, I suspect that there will be a new PC software that supports the MHO3 at some point.I recently received the programming manual in English.The memory is very large. With segmented memory you have far more memory than the two times 360 Mpts.The transfer of data from the MHO3 to the PC is very fast. I have achieved around 100 MB/s with FTP.Unfortunately, I have not yet managed to transfer the data from a connected USB stick to the PC. that would be nice.The free internal flash memory is over 20 GB.I think you could get even more out of the good hardware. More and more powerful math channels, larger FFT. Hires or Eres smoothing when sampling.The bandwidth is quite accurate. There is no such big addition as with Siglent. The MHO3-2504 has almost exactly 250 MHz bandwidth and the MHO3-3504 has almost exactly 350 MHz bandwidth.So my overall impression is very good. I am glad that I bought the MHO3.Best regardsegonottoPS: I forgot to mention the variable filters, which are very nice to have.

But if you buy an MHO3 and find a fault, you can report it to Micsig.

content: Hello,the MSP500 probe is a passive probe with Mic-OPI interface. So you cannot use them with your SDS2000X Plus. It can be automatically calibrated there is no trimmer.Yes, it only has one math channel that can't do much.I have had the MHO3 for six months nowThe variable filters are very good. The options for post-processing the data are much worse than with the Siglent. However, you can transfer the data to a PC via LAN at 100 MB/s using FTP and edit it there.The hardware is more powerful than Magnova:The maximum sampling rate is 2 x 3 Gpts/s.The memory is 2 x 360 Mpts.The total memory for segmented memory is probably 2 x 860 Mpts.You can make videos from the screen with a resolution of 1920x1200.

MHO3-5004 is the 12bit version with 500MHz bandwidth and it costs €3,750 without tax in MEILHAUS.I understand most probably the 250MHz version has the same hardware with the 500MHz version, but I guess I can not (easily) unlock the 500MHz bandwidth on a 250MHz version?

But I don't know that for sure.But it's very difficult to decide. I'm glad I don't have to make that decision.Maybe you buy an MDO5004 for € 2,021.81 and a Siglent SDS804X HD for € 486.71. Then you have the advantage of both worlds for relatively little more cost.The MDO5004 has a trigger out, so with a little care (delay and jitter) you can even synchronize both and then have 7 channels.Best regardegonotto

The built in power supply, PC, obsolete and irreplaceable CRT makes it really dated, and not really recommended for purchase.

I was not even familiar that you could update BW with license keys, on MHO3-series... not something Micsig seems to promoteI get that the hardware likely is identical across the MHO3 series from plain production convenience, so a 250MHz model (MHO2504) would manage 500MHz.(MHO5004) if you could hack it.What license keys.. did you try to use.. that flipped your bandwidth to 0Hz.?Are there any official licenses for MHO3?? On the older STOxxxxC/E the only license options, as I recall was some protocols, that was listed as "options" fx 429 and 1553B but I don't know if Micsig has activated 429/1553B with some of the updates over the years on these older legacy models..

All while "Micsig" was not even clearing bugs or delivering certain "things" they tried to indicate/ask owners/users here on EEVblog for, while giving the impression they would.I was more left with the impression that they just made some in-house videos. where they showed how people easily could check certain things... fx*this is how you relatively easy can check your Micsig scopes bandwidth, or this is how you can get an indication of the waveform update rate etc etc..

content: As far as the dual cursor control knobs LeCroy did that first way back in the 9400 series of scope in the 1980's for DSO's and kept that through the 93XX/LC/WR1 LT & WaveRunner 6K/6KA series and the MXi and other lab scopes. Much better than the scopes that make you use one knob to switch cursor function. They also had simple up and down arrows for the cursors insteadof the stupid lines that are used today. With the old system you could put a cursor on a single sample point in zoom mode.Sadly when they went to having their "lower cost" scopes made by Siglent instead of Iwatsu (Iwatsu built the hardware and LeCroy did the firmware) they abandoned the dual cursor knob system for the single one you see now, I really like knobs for functions. I think the best UI LeCroy ever had was the WaveRunner 2 6000/6000A series. A knob for every major function: A 4 channel scope with separate attenuation and position controls for every channel, 4 knobs for Zoom vertical and horizontal, Horizontal Timbase and Position, Trigger Level and a special knob for certain functions. You also had a touch screen that you can enable at the touch of a button. The screen was large enough and the measurement data was never displayed in the grid area only below it. A sweet scope to use.I wish they would bring back that UI in a 12bit version and forget about the Darth Vader black motiff. It should be somewhat easy for them to do these days as I am sure they have the firmware development paid off.I am imagining something like the Rigol DHO 1000 series hardware with LeCroy firmware just expanded a bit to handle the additional encoders. After all encoders are cheap!I just found the datasheet for the 6KA series and attached it for fun!SamW3OHM
