Whatever your sound card is capable of.

The AD2 software supports sound cards up to 384kHz sample rate.

In both cases not really silent but this is only disturbing when it´s totally calm in your room.

Which usually is, since I'm a silence maniac, and spent a great deal of money to build an ultra-silent desktop PC.

Truth being told, I think I want too much without having the budget.

Welcome to the club  8)

The best way forward is to make a short list with pros & cons and decide based on that. Whatever you buy now, you'll buy a different oscilloscope in a few years. Maybe even have two or more oscilloscopes which complement eachother. At the moment I have 5, each with their strengths and weaknesses.

It's in the ballpark of an MSO5000.

Bartronix sells the 4 chs with the joystics for 650 euros. Consider that AD2, impedance analyzer and bnc adapter are almost at 500.

I'd be 200 eur more than the mso5074. The Siglent would save me 130 bucks.
But apart from that, from what I've read about the Micsigs, they compare as follows with the 499$ siglent.

Micsig pros:
- Very good build quality
- Battery powered, portable.
- Snappy UI, with Android.
Cons:
- Not expandable with a logic probe
- No Bodes
- No statistics, as noted above.
- Not hackable to 200 MHz

Which he could do with a $499 DSO and webserver connection using his already acquired AWG, a Uni-T IIRC however I'm not 100% is anyone has scripted a Uni-T yet to talk to Siglent Bode plot control.
A $360 SDG1032X would fix that and still beat a MSO5k budget.

--- End quote ---

Indeed, no one has scripted for the UNI-T wg. I checked.

But Fungus is right in saying that the web interface will just make a mere 800x600 picture bigger, and more coarse grained.
OTOH, it seems there are no decent (100 MHz, good software) usb scopes for <1000 bucks. And software is very important if you are going to give up buttons and knobs.

Here is what I think will be the wisest purchases with my limited budget: The little Siglent and the AD2. Here is why:

I'll get a real scope with 2 ADCs, 100 MHz by default, possibly hackable to 200. This would give me bandwidth to grow within.
It can also mirror its admittedly puny 800x600 screen on a big monitor. Will look pixelated, but it can ease the effort on my eyes during long probing sessions, something that the Instek cannot do.

With the AD2 I'll have practical usb scope, with limited bandwtdth, but with very good software that will do fine with my 4K monitor. It will give me immediate Bode plotting capabilities. If I need more, at higher frequencies, I will buy a Siglent 60 MHz SDG in the future.

--- End quote ---

It would not be difficult to make such a machine. It's just that it's a terribly conservative industry, from what I'm seeing.
