3. Same question for Micsig ? There was a lot of topics about it in 2015-2017 but nothing since then. Latest firmware update is Feb 2017... Abandonned product ?
I have a MicSig TO1104 myself and tested it very thouroughly.
The TO1104 also offers input filtering which might be useful to turn PWM signals back into 'analog' signals by filtering the high frequency content away.
I think you'll be happy with the Siglent. The Siglent is generally well reviewed here and IIRC you can fairly easily mod it for increased bandwidth and additional features. You'll need to dig around in the big thread for that.
For what I do, the Micsig TO1104 covers nearly everything I need. I can get access to other scopes for anything not covered.
I think they've been busy with the ATO1000 version of the scope which added automotive diagnostics and the STO1000 version of the scope with adds a bunch of hardware controls. The latest firmware is v343 which came out around November 2018 to support the ATO1000 so it isn't abandoned. If you've got a TO1000 then you can unlock the automotive features with an additional license key. I've no idea how well the automotive diagnostics works but it seems to list a lot of different tests and options.
Rigol/Siglent/Micsig all have pluses and minuses you will just need to find your best fit.
For a function Generator go with an external one $50-150 gets you a lot of bang for your $ Feeltech or JDS you can later on if you need it spend more if you decide you need to. I am just going through the upgrade thing at present from a Feeltech 30mHz.
Have fun deciding
4. It seems that agilent leashed the megazoom asic in this unit... Any interesting updates to be expected or announced ?
Ok I probably missed it, the latest update I could find on chinese website is 273. Do you have a direct link to 343 ?
Automotive is not a major requirement (I have dedicated hardware for that) but it could be interesting to try out.
Yes I saw the STO1000 on chinese version of the website, not sure about the layout and quality of knobs/buttons but it could be the "missing link" able to convince users of traditionnal oscilloscopes (or outdoor users wearing gloves). Is this going on the market soon ?
I think that I read all forum posts about it, and I am surprised to see no attempts for hacking it (just one message mentionning reverse engineering but nothing happened). Is there a linux heart beating in there ?
The form factor and hardware are very nice and I am sure that community could add precious features if micsig were keen to provide scripting or user-extension possibilities. As a developper I would love to work on 'improving' such device !
I'm biased but one of the cheapest option is to buy an used EDUX model from Keysight, make the necessary hardware hack (or just go with the DSOX), then install the latest software hack too. It gives you a 2.5 channel, 200Mhz+ scope with a lot of decoder options and a super comfortable, intuitive, easy to use GUI.
I thought the 200MHz mod had problems and wasn't recommended? You had offset issues and the firmware was buggy in 200MHz mode. Modding a EDUX frontend to DSOX involved a lot of component changes as well.
Nope, not anymore, just look around the forum.
They have a 4 channel unit being released this month, but it's more expensive.
No word on Megazoom V ASIC development, but the new scope won't have it I'm sure.
BTW another unit in this price range is the GW Instek GDS1054B (around $350 IIRC). This can be uphacked (AFAIK) to have protocol decoding and more bandwidth using a key generator. The firmware is also solid on these units.

It does run Linux. It already does everything I need so there hasn't been any reason for me to hack it. I've poked around in the firmware updates for curiosity but that has been the limit of it.

The firmware is also solid on these units.It was in my list at some point but got dropped after seeing the teardown video and the UI which I did not like.
However I can get a "ISO-TECH 1054B" for cheap (300€) and I read somewhere that it should be a rebranded instek with compatible firmware... Correct ?
There is an interesting deal on ebay for the To1104 plus at 350€, free shipping from Hong Kong.
This does not seem to be the official Micsig distributor or store like they have on aliexpress
I'd buy a scope from a European distributor if I where you. Returning it for warranty will be easier. IIRC MicSig does seem to respond to direct warranty / repair requests but you likely need to ship your scope to China. Someone on this forum had a problem with the battery charger and he did manage to have it fixed but I don't know the details from the top of my head.
Which one are you looking at?

How about official Micsig store on aliexpress ?
