WOW that's quite the budget....
I took this from an article online
Understand that today's signals are no longer pure sine waves, but most of the time square waves. These are built by "adding" the odd harmonics of the fundamental sine wave together. So a 10 MHz square wave is "built" by adding a 10MHz sine wave + a 30MHz sine wave + a 50MHz sine wave and so on. Rule of thumb: get a scope that has a bandwidth of at least the 9th harmonic. So if you're going for square waves, it's better to get a scope with a bandwidth of at least 10x the frequency of your square wave. For 100MHz square waves, get a 1GHz scope... and a bigger budget...
So that being said unless you have a 500 Mhz scope lying around skip that sig gen. The cheaper rigol DG1022 is perfectly fine for the money.
On top of the sig gen your getting the sig gen option for the 1000Z... Why?
Power supply. I'd get a Rigol DP832 without the A since you can add all the features of the A model for free with the keygen...
Multimeter again are you sure you need 6.5 digits for 99 percent of projects it's overkill. Maybe the 5.5 440$ DM3058E would be enough I know it's missing lan.
Or take a look at this
https://www.eevblog.com/forum/buysellwanted/(fs)-rigol-dsa815-tg-open-box-(more)/ Pete from TEquipment was selling open box stuff for pretty good discounts one of the items presumably still available is the BK 2831E 4.5 meter for 290 however I bet you could negotiate a price closer to 200 flat (One other user went from ~350 to 260 on the same thread).
Oscilloscope good choice, skip all the paid options Seems like you went for it all, why buy in excess? Anyways all those options can be had for free with the keygen.
You haven't indicated whether your a beginner to the hobby or you know your shit. If you are in fact a beginner most of this stuff seems like overkill. IMO better equipment won't make you a better engineer. Buy what you need and don't buy for the sake of buying who cares if it offers good bang for buck compared to the rest...
Also idk if you have it already but I'd suggest a few more things
A solding iron (Hakko FX-888D, Weller WES51 both perfectly fine for a hobbiest especially beginner both sub 100$)
A handheld meter sub 100 in the US you have tons of options, Used fluke 85 or 87 I,II, or V (all go sub 100 on ebay with patience), Amprobes, even Uni T look around the forum there are tons of reviews for various meters
I don't mean to be rude, condescending or insulting and I by no means am I an expert (I'm only in my 3rd year of Comp Engineering). However unless you know that you need all this stuff and the functionality as soon as you get it, don't spend 4k on your lab. Things will get faster cheaper smaller as time goes on.
