Hi shakalnokturn,
What measure do you made?
On me is working but you want to do other type of measure perhaps ...

Hello skander36,
Thanks for your screenshot, at least it got me thinking...
My bad: I haven't used this scope that much (I have too many scopes) nor read the manual enough, I was confusing the "High capture rate" and visual persistance.
I can do cursor measurements with persistance enabled but not with high capture rate enabled. The measurements then read as "-1".

Hi, where is this setting?
Mine is STO1152, but I can't find this seeting.

On my TO1104 it's in the bottom menu that also allows you to take screenshots and enable "all measurements", it's an icon that looks like a sinewave.
Shown to be active on my screenshot by the red "H" next to "Run".

#1 - Does anyone know how many FFT points the 1104C and 1104E have? I can't find this anywhere
#2 - Can it operate without battery? This battery will die in a few years.

Aint the max "FFT points" on these Missig scopes, just the highlighted number in red' when you're in FFT.?
Something like.. TO-series around 43k and the STO (1000C series & perhaps 2000C series) around 88K and the new Joystick (STO1000 & 2000 non-C vers.) around 100k, same as the older STO-E-series which I also reckon were at 100k FFT-points.??

fx here 87.5k.?

Noticed bug in Micsig STO1104E Plus. Zoom in during stop mode (10ms/div or slower) shows empty screen with fastest time bases.

Setup - single channel enabled, normal sampling, auto trigger mode, edge trigger, auto memory. Set time base to 50ms/div (70M, 100MSa/s), then stop scope and zoom-in to max level - 2ns/div does not show any data points. Sample points on 5ns/div are still visible, sample size is enough to be shown on 2ns/div.

Doing the same from 10ms/20ms/... divisions scope also get to 2ns, but no data is shown on the screen :( There are some samples for these timebases to display but for some reason it is not shown.
Both vector and dot mode works the same. There is difference on whether memory size is auto or manual, but the bug persists.

Auto memory, single channel enabled:
  • 5ms/div, 70M, 1GSa/s, visible to 2ns/div
  • 10ms/div, 70M, 500MSa/s, visible to 2ns/div
  • 20ms/div, 70M, 250MSa/s, visible to 2ns/div
  • 50ms/div, 70M, 100MSa/s, visible to 5ns/div, 2ns/div not visible
  • 100ms/div, 70M, 50MSa/s, visible to 10ns/div, 5ns/div not visible
  • 200ms/div, roll mode, 700k, 250kSa/s, visible to 2us/div, 1us/div and faster not visible
With with max memory (70M) enabled manually:
  • 200ms/div, roll mode, auto - 70M, 25MSa/s, visible to 20 ns/div, 10 ns/div not visible
  • 500ms/div, roll mode, auto - 70M, 10MSa/s, visible to 50 ns/div, 20 ns/div not visible
  • 1s/div, roll mode, auto - 70M, 5MSa/s, visible to 100 ns/div, 50 ns/div not visible
  • 2s/div, roll mode, auto - 70M, 2.5MSa/s, visible to 200 ns/div, 100 ns/div not visible

This a bug in FW - sampled data is not shown in fast timebases. Can anyone confirm this issue?
@Micsig_support, is there FW update planned for STO1000E series?

EDIT: Micsig performance described below is not a bug. I missed trigger source setting as pointed out by OP.

Noticed feature in Micsig STO1104E Plus. Max sample rate is 1GSa/s (with single ADC) for one channel, but only if that channel is set to trigger souce. Otherwise max sample rate for channels 2/3/4 is halved to 500MSa/s.

Test setup: auto trigger, auto memory, 5ms/div.
  • Enable channel 1 - 70M, 1GSa/s, OK
  • Enable channel 1 & one of channels 2/3/4 - 35M, 500MSa/s, OK
  • Enable channel 1 & two of channels 2/3/4 - 17.5M, 250MSa/s, OK
  • Enable channel 1 & all of channels 2/3/4 - 17.5M, 250MSa/s, OK
  • Enable single channel from 2/3/4 - 35M, 500MSa/s, only half of sample rate and memory because trigger source is channel 1
  • Enable 2 channels from 2/3/4 - 17.5M, 250MSa/s, only half of sample rate and memory because trigger source is channel 1

Auto memory or manual memory (max or min memory) setting does not affect this reduced sample rate for channels 2/3/4. Same logic persists going though different time divisions.

This is not a bug, it is just how scope with single ADC works. Keep in mind that trigger source keeps that channel on even when channel is turned off.

:palm: missed trigger source setting. As one could expect, trigger source effectively turns on channel by default even when it is not shown on screen. So there is not bug related to max sample rate and memory size. But bug with empty screen with deep zoom-in still persists.

Set time base to 50ms/div (70M, 100MSa/s), then stop scope and zoom-in to max level - 2ns/div does not show any data points. Sample points on 5ns/div are still visible, sample size is enough to be shown on 2ns/div.
See captions below with a display bug (described in detail above in previous post). STOP/RUN mode, regular zoom with a knob or with zoom display show the same picture.
When zooming from 50ms/div (100MSa/s, 70M) to 2 ns/div, display does not show any dots (in dots mode) or lines (in vector mode). Arrows point to sample points locations, which are 10ns apart (100MSa/s).
5ns/div mode shows 7 sample points/ 2ns/div should show 3 points, but none is visible :(

Hello eevblog community. I came here to ask whether someone here might have some insights into jailbreaking the android that runs on these micsig oscilloscopes?

So far i couldn't install third party apps, couldn't enable developer mode or find a way to access the bootloader.

I am still looking into it and would be happy if someone else has any insights to share.

I guess i'll post here on my progress:

- The SATO1004 has a aarch64 based rockchip SoC.

- First connecting it to usb c and then to AC while powered off, then powering on, yields a screen showing "Upgrade mode".

- The device will identify as fuzhou rockchip device and can be read from and written to using rkdeveloptool:

https://github.com/rockchip-linux/rkdeveloptool

This can also be used to create full images of the device's internal memory as well as write them back to the device if anything should go wrong.

I will keep you updated if i make any further progress, currently downloading the image from the device to further look into.

I was just looking at a the new Micsigs and I don't see a button to go directly to the trigger menu like on the old ones....



Is it true?? Surely there must be a shortcut for that.

I'm sure you can get there that way, but ... the button was a really handy shortcut to go there directly.

Edit: I see you can slide out a trigger menu, as shown in this video at 27:50

Is the only difference between the STO1004 and SATO1004 the automotive test features?
Main thing I'm interested in that I can't find for sure that the SATO version has is the intensity grading, and it's not entirely clear from the manuals or information I've found.

Took a brief look, also cant validate it , when it comes to the intensity greyscale grading or the temperature color corrected, Micisg labels it as "CCT"
but Micsigs intensity-grading is IMO quite good with many levels.. can't recall if it's 256 or 512.

Micsigs CCT and the adj. BW filters. (both are two critical features, I often use but its the older knob-model https://tinyurl.com/mr35eeb3)



Im pretty sure the SATO does have intensity grading, as it would be a weird thing not to implement, but Im starting to second guess, when looking at the brochure's. (English) as nothing pops up when searching for CCT or intensity or grading, but I only just skimped the manual briefly, as it is like 441' pages with pictures, pasted below.

Micsig STO110E Plus has small bug in channel high/low pass filtering. High/low pass options show nonsense result until some limit value (MHz/kHz) is entered. Limit value by default is blank for high/low-pass and thus by default produces wrong result. Full BW and 20M BW options works fine. FW is the latest available at the time of posting.

Setup:
  • enable one channel, AC coupling, auto run mode, measure something stable (output of DC PSU or battery). Zoom in the lowest V/div.
  • Go to channel options, it will show full/20M/low/high-pass selection. Note that limit value (in rectangular window) is blank.
  • Select full BW or 20M BW - 20M works as low pass, full BW shows more noise.
  • Select high-pass. All screen is filled with much higher amplitude wrong signal (oscillation).
  • Select low-pass. All screen is filled with much higher amplitude wrong signal (oscillation).
  • Press on blank square, enter MHz or kHz value. Now low/high-pass options seem to work normally.

EDIT: added screen shots.

It's been like that for a long time like a year or two.... if I recall at least OTA xxxxx28 and xxxxxx29 got that annoying bug with the high & low bw filter going berserk...so I don't use those OTA vers... tend to use the vanilla that is hardbacked.. I reckon it's xxxx08.

- but it creates numerous problems also for ref. that will flood the screen.
its a shame about the bandwidth filtering, as it's otherwise very good... with manual control

It looks like they simply forgot to put in the entry values for high & lowpass, which both have manual adj. control, and it will flood the screen with rubbish, and you need to dial in a value before it will play along.
Can be seen at 1.05minute below on a STO1104C.. it gives a lot of nonsense..

I reckon everybody has gone home at this Mc-Micsig-company and they simply don't give a flying d*uck..
but at least I can still slurp the vanilla ROM, back'ed in (xxx.08) which is solid...Micsig bandwidth filtering, and their gradings with CCT, were otherwise top nudge

This is a little program I wrote a while back for my Micsig.

Normally the screenshots come out a bit dim when copied to the PC. I think the 'scope uses a different gamma curve for the screen or something. This program adjusts it so it looks better on PC.

All you need to do is drag your screenshot files (.png format) onto this exe and it will fix them and save them under a new name (same as old name but with added underscore character).

Hope somebody finds it useful...  :)

Edit: Here's before and after:


nb. It's Windows-only.  :D

Well done Fungus, You should show an example of your program "A vs B picture"  :-+
//  seems my system was the only one giving notice, so likely a false positive..(screensdumps of virus present sent to PM)
Btw which Micsig scope do you got.? STO1104C? and what OTA-scope update are you on.?

That confirms the filter bug, I see the same behaviour. With empty filter cut-off value nonsense is shown on a screen.

I would day that Micsig is not that bad w.r.t. FW updates and is better than Rigol (DL3000 DC load has bugs and so much potential with better FW, but there is zero response so far :()
There were quite a few Micsig updates, even recently (but just for small bugs IMO, as I didn't see change log anywhere). However, more serious requests for improvements are still on the table (like fine control, statistics trend, zoom bug, etc.).

Oh, duh! Screenshots added above...

Microsoft Defender (Antivirus) is not that fund of your program, but it goes without saying it can be a little hysteric at times, not least for homebuilt exe-programs.

Btw which Micsig scope do you got.? STO1104C? and what OTA-scope update are you on.?

It's all my own code and I compiled it myself. MSD doesn't complain here...  :-//

What message do you get? Does it say it's a virus or just that it's "not a very common file" (or something like that).

Mine's an STO1104C.
