The attempt of a Micsig (A/S)TO11xx general purpose thread ... :-)

ruhnet:
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.

// It could look like the SATO perhaps doesn't have it. as it aint highlighted on the SATO's datasheet, as the case is with STO/C/E & ETO series but I cant say for sure.. :-//

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

Fungus:
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...  :)

nb. It's Windows-only.  :D
