However, I am certain that I want to learn electronics more. I just completed my sophomore year studying electrical and computer engineering at college, and realizing more all that I do not know. I hope to use this 'scope for a better understanding of my homework and labs when I am not able to be in the school labs. Therefore, does the DS1054Z 50 MHz bandwidth seem too low for you?
As you state later, the 50 MHz bandwidth is before 'unlocking'. The actual measured bandwidth, after unlocking, is around 130 MHz.
Or is it maybe better than the DS1202Z since it has 4 channels? The other is 200 Mhz, but then again the DS1054Z can be brought to 100 Mhz. So all in all, is it better to have more bandwidth and less channels, or more channels and less bandwidth (if we had to choose)? I know it would depend on my use case, but perhaps there is some general answer as again I do not really know my use cases; rather, I know I am going to be using this in tandem with my classes in college.
That is always the question. Four channels is nice for decoding the SPI protocol. To be honest, I spend 99.9% of my scope time with just a single channel. Sometimes 2 channels and only rarely all 4. I have the DS1054Z. It came out years before the Siglent but today I would buy the SDS1104X-E and unlock 200 MHz.
Then, there is the Sigilent 1202X-E, or even the 1104X-E. I know there is quite a bit of writing about these in this forum, but I am still exactly unsure how they stand up against those Rigols.
The big complaint about the Rigol is the slow user interface. The Siglent is purported to be much better in this regard. The Rigol was first, Siglent came along and improved the shortcomings of the Rigol. But the thing is, just exactly how much time does a user spend with the UI? For me, it's not very much. Speed isn't an issue - to me.
And, being that the 1104X-E can be 100-150 dollars more, plus all of the extras that I do not think are standard (maybe they are now for Sigilent? I know Rigol made all of their extras standard), I am not sure if that specific Sigilent is worth the extra money for my general case. But then, the Sigilent 1202X-E is the same price as the Rigol 50Mhz 4 channel, but this Sigilent is 2 channel with 200 Mhz.
So to summarize: I'm met with the question of Rigol vs. Sigilent, and the question of 4 channel 50 (or 100) Mhz vs. 2 channel 200 Mhz.
I know this has probably been brought up before, but again I am asking for my non-specific use case as well as to get the most up-to-date advice. I am so appreciative for your expertise.
It's brought up a couple of times per week - 3 in the last week. Kind of a bumper crop.
I bought the DS1054Z a couple of years before the Siglent SDS1104X-E was released. It was the hottest thing on the market and it's been an excellent scope. Today, I would buy the SDS1104X-E and unlock 200 MHz because bandwidth is good and I would still want 4 channels.
You can get by without technically sufficient bandwidth in many cases but if you need more channels, you're out of luck. I got by with a 10 MHz Heathkit for a very long time. We don't always probe really fast signals. Even with my 100 MHz FPGA projects, that's the internal speed. On the external signals, 10 MHz would be about as high as I go.
I probably wouldn't shell out the money for the SDS1204X-E when I can unlock the bandwidth with the SDS1104X-E. I haven't really researched unlocking the Siglents. More info over in the Test Equipment forum.
OTOH, if I was a student, I would think long and hard about the Digilent Analog Discovery 2. There's a reason my grandson's lab course used this device. Probably price but more likely the high degree of integration and functionality. Download the Waveforms software and play with the 'Demo' device to get a flavor for its capabilities.
Start with reply 52 here and follow along for 4 experiments:
https://www.eevblog.com/forum/testgear/starter-scope/50/A couple of those experiments seem pretty important and they are darn hard to rig up with a scope and waveform generator. The Siglent can do some kind of Bode' plot but I haven't seen the printed output and I think it requires a Siglent waveform generator.
Don't overlook the capability to annotate the plots to emphasize various features. This can also be done with most scope images but not nearly as easy because it has to be done after the image is captured whereas annotation becomes part of the image on the AD2.
I'm having a little problem getting things set up but the idea that the AD2 can be integrated with MATLAB seems pretty compelling.
There's also the 27" monitor versus the small screen size (even if it is large by previous standards). There are also voltage and frequency constraints but there are a large number of tools in a simple package.
Follow along in that thread with the experiments where we discuss some of the limitations.

I didn't look for accessories or any kits. Don't forget, Digilent offers a student discount on the AD2 and the accessory kits.
