If I was a student and realized that I needed both a scope and a signal generator and it would be handy to have a spectrum analyzer for Bode' Plots and FFTs along with a couple of power supplies and a logic analyzer along with a digital pattern generator, I might look seriously at the Digilent Analog Discovery 2. This device was invented for students. The AD2 and a laptop form a lab in a backpack.

I can couple the Waveform device square wave output directly back into a scope channel and display the FFT of a square wave. Or, I can use the same square wave to charge and discharge an RC circuit and display the waveform. Sure, we all know what it SHOULD look like but with a couple of components, we can see what it DOES look like.
You can download the Waveforms software and look at all the gadgets in "Demo" mode. Having the software running on a Raspberry Pi 4B seems pretty cool.
Look at the weird prices on eBay! They're all over the map and even the original version is selling for a lot of money. After graduation, sell the AD2 and buy something that takes more space. In the meantime, you can do your lab work with the AD2 while sitting in a coffee shop.
A lot of folks just want a bench full of boxes and I'm no different. But when it comes to convenience, the AD2 is way above everything else. It doesn't have huge bandwidth but it has more resolution than you're likely to find in a reasonably priced scope. It is definitely NOT a toy! If I were a EE student, it is the first thing I would buy. I would buy the student kit and add whatever other gadgets and parts kits I could afford. The capability is amazing!
A while back I was helping a friend with an FPGA project while enjoying coffee at Starbucks. Here we were, at a small table, with 3 laptops open, two FPGA boards being programmed while sipping coffee. It doesn't get any more 'geek' than that! Alas, I don't think a pair 70+ year old retired EEs can be considered geeks. Too old... People were probably laughing...
