The reason I am looking for a test setup is to experiment on other circuits that were not covered in labs like Class A amplifiers and also have some side projects to strengthen my practical skills and to able to design actual hardware instead of just being able to do well on exams.

If that is the main intent, I would not recommend any more an educational devboard like Analog Discovery or Adalm2000.

Would be better to to have lab instruments.  If the budget is very tight, maybe build the more simple ones, like power supply, a soldering station, a low distortion audio generator, and so on.

I disagree, unless you can enumerate why an AD is insufficient, plus why a set of lab instruments is necessary, plus how much of their time it will take to buy and learn to use those instruments.

Personally I doubt that would make a student much more employable. One year of experience repeated twice does not equal two years of experience! Ditto learning two scopes' foibles.

Any decent employer will be impressed that they
* did more than necessary
* can say what they would do better next time
* can say what they weren't able to do because of the equipment limitations
* and even more impressed if they then found a way to work around the limitationsand will be prepared to train them to use whatever equipment the employer needs them to use on the next project.

Looks to me like the OP already knows the basics, and now would like to rather have an EE lab.  At about the same price as an AD without discount, one can buy instead a Siglent SDS804X HD, and unlock it.  That DSO will be a tool that will serve any EE lab for many years to come.

I didn't compare them side by side, but the new 12bits DSOs seems to be way more capable than an Analog Discovery (thinking of this thread in particular:  https://www.eevblog.com/forum/testgear/sds800x-hd-review-demonstration-thread/ )

Hello,

I don't think you can compare the two.
Suppose the OP wants to try a Gilbert Cell. With an AD and a breadboard and the necessary components, he can do his experiments.
He can't do that with an SDS804X HD because he doesn't have a power supply, he doesn't have two function generators, but he has a nice scope.
The AD is a small laboratory and not just a scope, and the differential inputs are also very practical.

Best regards
egonotto

PS: An AD and an SDS804X HD and a power supply would be ideal, but that costs more than $250

RoGeorge:
For a Gilbert cell, a phone charger (or just a USB cable) can be the power supply, and a sound card can be the dual channel generator.  Then the oscilloscope can be used to visualize the signals.

Should I get the Analog Discovery 3 with student discount ($250) or a budget bench setup consisting of Hantek DSO2D10 ($150, being aware of the potential freezing issues) and Korad KA3005D ($50 from taobao)? I would like to start small first with a budget of $250 and see what I am really interested in down the road.

Invest your time and money  in math, forget about the iron. LTspice is more than you really need at that stage of eduction, use labs of your university ...
