Haha, yes, I only realized later that they're simply dividing the number of error frames by total frames received and multiplying by 100 to get an error percentage. Dividing by zero fails, and you get a NaN haha. In the video, I assumed that they were calculating errors based on what's in the buffer, but that's not the case. It's just a statistic.

I agree haha, and I realize that this would be a very rare use case for anyone else. I just thought the way in which it failed to display the characters was interesting.  :) Since I wanted to release this review quickly, I didn't have time to plan out any other more elaborate bus decode tests, but I will in the future. Very glad to hear that I2C works well - I haven't tried it yet.

Agreed, it couldn't be simpler to implement. Doing some running or even total averages costs almost nothing computationally. Maybe eventually!

It could be me BUT one thing I really hate is the amount of space the screen borders take... (1-inch plus)

I still think that they owe us that bought STO C series (one with proper buttons and knobs) an update that will give measurements statistics.
That is my biggest problem with otherwise really great simple little scope.
Some cheap 50 USD crap has statistics...

In meantime they developed STO E series, and two new generations of hardware (even segmented capture) but they don't know how to make simple statistics..
New scopes (despite more powerful hardware) are basically same as old ones in capabilities.

While I like the scope and company, I don't think that they can go forward without fixing some of the major flaws.
While old ones were small, simple and cheap but nicely made and useful tools, to move forward (and I presume new ones will be much more expensive) why would anybody buy it if it cannot compete in basic features.

Also, my STO1000C is few years old and seems like abandoned platform.. No new development. Even really simple (and basic) stuff like measurement statistics..  Makes you wonder if that is the policy?

The screen's quite big for an oscilloscope, but ... I guess the case is even bigger.  :)

Seems more or less the same, with specs as the E for the STO1000 (non-C variant)

Model   STO1004
Bandwidth   100MHz
Analog channels   4
Sampling rate   1GSa/S
Memory depth   70Mpts
Waveform capture rate (Max)   130,000 wfms/s
Bandwith limitation   20MHz, High Pass, Low Pass
I/O port   Wi-Fi, USB 3.0/2.0 Host, USB type-C, Grounding, HDMI, Trigger out
Display   Industrial 8 inch TFT-LCD (800*600),14*10 grids
Dimension   265*192*50mm
Battery   7.4V,7500mAh

Dimension has changed a little from the STO-C model.
New STO1000 series 26.5x19.2x5cm
Checked the older STO1000C 28x18x5cm so the new (non-C) is a tad higher +1.2cm and -1.5cm shorter.

Looks to be the same 8" 800x600 TFT from the previous gen's that obviously chokes from a low-based perspective, as TFT usually does.. and it's not a bad TFT screen per say, and quite useable outdoors with peaks up around 415nits, but that is obviously taken under different aspects, while in browser to pursue a white background and not in the scope app.
TFT LCD screens seem to be common in electronic measurement gear, as we also see a TFT in the new MSO2x- series from Tek.
But definitely, not a fan that Micsig ditching the clickable-rotaryknobs for some small 4way joysticks..I keep coming back to using the knobs.

One thing I really like about these Micsig scopes - is their color intensity (CCT) and also their overall intensity-grading that seems pretty high in grading-number.. like up around 256 levels, certainly decent..

Checked the wfps on the older STO-C model - as far as I can tell, it peaked at 103.000 but mostly was around 95.000, but I was using limited gear - to take the freq-reading, and will obviously vary greatly on the settings..  https://i.imgur.com/nNcrhSz.mp4
but around 100k, as wfps peak number' ain't bad in this handheld price-segment and the official specs claimed above 80.000 - if I recall correctly for the 1000-C series, so it seems to fit.

I like that they added more USB ports on this 2022 variant, even USB3 and TypeC.. I do find it very useful to power gear, like fx signal generators like
 my old FY6900-60mhz or extra displays etc, with these USB ports..though, im not sure the purpose of them in the new model and to what extent you can use them.
I don't use it for video or pictures etc, as its so much easier to just log onto the scope's IP in a browser, and download content by WIFI.
On the old C-model and power, I tend to use either power delivery (PD) TypeC power banks with a TypeC to Barrel DC PD-trigger-cable (12v) or these adjustable 3v to 24.6v DC power banks that can go up around 100watt, as the included 12v 5A PSU is a noisy fellow.
The old model consumes around 21 watts when charging the inner battery, while turned off, - and in use' it peaks around 31watt when I looked at the power bank display, so it ain't a lot it's using.. and should be easy to supply 12v power on the road
