Equipping my first home lab. I kindly ask for your help with suggestions
(1/4) > >>
TheKid:
I am a seasoned professional who works with low-level firmware and some hardware debugging. I am looking to build my own lab at home and my budget for lab equipment is $2500USD. Trying to get the best bang for the buck equipment. I have done some research but there are so many options out there and it's hard to tell which buys are good with my limited budget.
I will be taking on fairly complex projects for an individual and am familiar with using all sorts of testing equipment professionally.

For the PSU I definitely do need 3 channels so far I have specced out these two
1. Siglent SPD3303X-E
2. Rigol DP832
I prefer the Rigol because for me the 3rd channel is essential and it seems with rigol all 3 can be programmed. Siglent's 3rd channel is fixed.

For the DC Load I'm split between
1. Rigol DL3021
2. Siglent 1T8511A+

I also need an Oscilloscope with minimum requirements of 4 channels 100Mhz and 1GSa/s. I was thinking about Rigol MSO5104 ~$1300. I can't find anything that is comparable to this. I am interested in hacks that increase functionality without hampering its use. I don't know what hacks are still viable.
Also, I am genuinely thinking of just getting something cheaper, like say in the $500s range while keeping up with mentioned requirements and just buy a Saelee Logic Pro 8 that is ~1k. I have not really used the Digital functions of the oscilloscope at work(please change my mind). I use a Saelee for I2c, UART etc. It has a good search function too.

My tentative budget allocation is like this.
PSU+ Load + Ocsilo/with digital functions(or saelee)
$400+$500+$1500

I will mostly deal with digital electronics and circuit board design for battery-operated devices.  I foresee possibly doing some kind of power use analysis on the hardware I design but that is the most I will be needing in terms of special functions.

I am open to other brands but I find that Rigol and Siglent have the best bang for the buck. I don't mind used items but the hassle that comes with it is just not worth it unless there is a local pickup which I have not been able to find good ones in Atlanta.
nctnico:
Look at the GW Instek GPP-4343. Neither of the power supplies you are listing are very good in terms of useability. On top of that the GPP-4343 can also act as a load.

GW Instek GDS1054B or MicSig TO1000 series are also nice oscilloscopes for a low price.
bateau020:
If you are focusing on battery operated devices, a low cost power analyzer like the Joulescope or zs-2102-a might be interesting. For power drain profiling, you may want more resolution than your average scope can give you.
For a low cost scope: stay away from the Rigol 1054Z, as the protocol decoding is flawed (only based on on-screen frame, not in-memory). Siglent SDS1104X-E is better in that respect, and hackable to 200MHz. I also found a low voltage differential probe to be invaluable, as scope's MATH functions have always disappointed me.

You can get the MSO5074 for $1000 and unlock the extra bandwidth, it's easy (and reversible).
