Quote from: mvno_subscriber on 11 Jun, 2024 09:32It's easy to get sidetracked by all the different specs and apparant shortcomings. As mentioned by others, I guess I have to be more precise as to what I'm looking for.So here's a try, in no specific order:
- Adjustment: 1mA resolution is plenty good enough for me
- Current ripple: 10mA constant ripple current sucks. I would prefer better, but in worst case I guess I can compensate with static loads as long as I know it's there.
- Software: This is important to me. Buggy software is a no-go, because I'd end up not trusting the instrument. And getting really frustrated
- Features: Static and dynamic loads are important. Also, being able to whip up a CSV (or whatever format needed), pop it into the USB port and execute it is a bonus I'll appreciate
- I/O ports: I guess it's nice to have. But no requirement, really.
- Screen: I like to be able to view graphs on an LCD. There should be a real good reason if I'm to go for something with text only.
- Build quality: I expect it to last 15-20 years at a minimum. Anything less would indicate a faulty design and I'd feel uneasy. Cheap plastic etc is ok, I'm not too picky about it as long as it works.
- Power: 200W is plenty. 150W would work too.
- Seller: I prefer to buy from reputable sellers. Elfa Distrelec, RS, local companies. Maybe I'd try Batronix, but I prefer sellers that offer DDP shipment. I have an assumption that makes everything warranty and repair related stuff much easier?
- Price: The B&K 8550 is really a bit more than I feel comfortable with, unless it's super duper cooler than the competition. The Rigol DL301 / Sigilent SDL2021X-E are also expensive, but seem to be a good balance between price and functionality
You keep referring to this Siglent SDL2021X-E in numerous posts.. Im not familiar with that model and I guess your a thousand too high.Have you examined a bit, perhaps watched or read a few reviews of modern programmable electronic loads.?
