New 12bit 500MHz Micsig MHO3 WITH knobs [Mic-OPI] MHO5004-12bit / MDO5004-8bit

[egonotto]

Same for previous models with built-in-WIFI.

Hello,

I tried the Python program, but it didn't work.
Then I changed it, but the samples I can get at once are relatively few. 2000 samples works, but 20000 samples no longer work. Enclosed is also the error message.
Does anyone have any idea what I am doing wrong?

Best regards

Hello,

2035 samples still worked, but 2036 gave an error message. The NI Interactive Console has crashed. I then tried the Visa from Keysight. That didn't work at all with my Python. Now I have installed the VISA from R&S. With this I can at least load 8100 samples at once. The “binary” samples consist of four ASCII numbers 0 to 9 and A to F.

With putty I was able to read the 36000 samples at once.
So it is somewhere with the VISA driver and pyvisa.

An update for people that do have MHO models and looking for WIFI access, and a relevant module/driver
I can see Micsig officially lists this model as their WIFI module for the MHO-line, not least MHO3.
Its looks like an off-the-shelf model, but I cant say for sure.

When doing picture-search on Aliexpress. it looks a lot like this model below to a tad under 5 dollars.

Hello,

in this video

the MHO3-3504 does not have a trigger output.

Hello,

I tried Rustdesk once. This is an open source software for remote access and support. I got a very small window on my PC, but that's as far as I've gotten so far.
If I understand it correctly, it should be a kind of web server.

An update about a new modular entry to Micsig's 3-series. 
Modular Micsig MO3-line [MO34-250, MO34-350, MO34-500] https://www.micsig.com/MO3/

Hallo,

It would be nice if the streaming option were also built into MHO3.

A data sheet for the MO3 and MHO6 would also be nice.
Without a data sheet, you don't know what you're getting.

Also a documentation of the bin-file format would be nice, I already have a rough idea.

An update about a new modular entry to Micsig's 3-series. 
Modular Micsig MO3-line [MO34-250, MO34-350, MO34-500]

Very interesting. One of the drawbacks of Oscilloscopes, Spectrum analyzers and so on, that the UI gets dated over the years. There are perfectly good scopes with black and green CRT display, that would be perfectly adequate with a modern LCD. The built in power supply, PC, obsolete and irreplaceable CRT makes it really dated, and not really recommended for purchase. This side steps the entire part, has a HDMI so it can work standalone without PC. Very nice.

[egonotto]

Hello,

how can you control the MO3 with HDMI only?

I assume they use Rustdesk.

Until HDMI is phased out in favour of display port. Anyone remember DVI?

Many devices can be upgraded with an LCD panel though with some hacking / modding. At some point you can pick-up the display data in digital form and feed it into an FPGA to create a TFT compatible interface. I've done that a couple of times already.

Hello,

a short, simple video that shows the reaction speed. The white circle shows my finger on the touchscreen,
An 18 Mpts file is written to the internal memory. In the video you can see how long it takes. The 36 MB file can be transferred to the PC via FTP at around 100 MB/s. The transfer therefore takes less than 1 second.

Hello,

my MHO3 has just had its first birthday and now has a bandwidth of 350 MHz.
Happy birthday MHO3-2504

Enclosed I have repeated the first noise measurements.

A free BW upgrade from Micsig down to the annual anniversary??

Hello,

my MHO3 only had a bandwidth of 0 Hz after entering license keys. As a result, the filters no longer worked. Micsig helped me to solve the problem. They kindly gave me a bandwidth update to 350 MHz.

Best regards
egonotto

[DaneLaw]

I see.. I was not even familiar that you could update BW with license keys, on MHO3-series... not something Micsig seems to promote
I 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..

[egonotto]

Hello,

ARINC-429, MIL-STD-1553B were not on the license list. But you could use it.
I asked Micsig and they gave me the license keys. But after entering these keys, the bandwidth was 0 Hz and the filters no longer had any effect.
The real bandwidth was over 500 MHz and there was some interference.

Micsig then helped me.

Hello,

There is now a new series without screen:

"Micsig MHO34-250 Modular 12 Bit Oscilloscope
The Micsig MHO34-250 oscilloscope (250 MHz) can be modularly synchronized and expanded to obtain more channels."

Other name: MO34-250

Has anyone done a teardown or (credible) review of this yet? A quick search of Google and YouTube turns up nothing.
It's been on the market how many months at this point?

It likely depends on what a "credible" review is.?

Is it a loaded product placement, where a given vendor contacts some western "influencer" and then either pays that "influencer" in cold cash to push up on a given product, or simply by the value of the product in an attempt to promote it on their behalf, while also giving some affiliate-salelink that again easily can taint the waters for that influencer and cater to a certain narrative in an attempt to get some action on his affiliate-salelinks.

I don't think Micsig does a lot of that nowadays, they tried it for a few years some time back, by giving some of these far from ideal YT-channels (free items) but I don't think people really liked it..Not least owners that had actually put their own funds behind it and dealing with bugs and then seeing some relative clueless YTchannel, being lubed five ways to Sunday by doing a brief unboxing, turning it on, and calling it a day..Without giving any actual, useful details... 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..

Hello,

the built-in calculator of the MHO3 seems to have a lot of digits. At least more than 500. The value in the picture is a part of Pi.
The last digit in the picture is probably the 513th digit of Pi.

Best regards
egonotto
PS:
The value of 100!

[DaneLaw]

How is Micsig's advanced math abilities from a single channel perspective?

Is it the same palette on current MHO-line models?

It's likely straightforward for people into calculators and know their formulas.

[egonotto]

Hello,

looks similar.
