I´m not a Siglent fan. ;)
Siglent makes good stuff for the money, that's why I have some of it.
But you can't do everything well, I don't know what they're like in terms of supplies and loads.
But yes, the SDL would also be something, especially as it seems quite cheap.
I think I'll buy a ready-made load and rebuild Blackdog's project, I'm currently designing a circuit board for it.
I'll have a look at the loads mentioned, thanks for the input so far. :-+

How about KEL2000 series?

These are quite good (the KEL2010 would fit Martin's requirements) after you move the transformer away from the analog control section. Still, single digit mA accuracy is getting into SMU territory.

Some test data can be found here: https://www.eevblog.com/forum/testgear/korad-kel2010-multicomp-mp710771-review/msg4975759/

Martin72:
OK,
These three are currently being debated:







Strictly speaking, the smallest Korad is dropped, leaving the second Korad and the Siglent(1020X-E).
According to nctnico's report, I would have to tinker with the Korad to improve it, which somehow doesn't suit me.
I don't know what to expect with the siglent, but I could easily get it and send it back relatively easily if I don't like it.
I would test it like nctnico did with his Korad.

I had a KEL-103. I liked it for the couple of days that it worked but it just stopped working out of nowhere. The input terminals got shorted and I have no idea how. I was fortunately still in the return window so I didn't tear down or do further investigation. I do have the Siglent SDL 1020X-E right now and it is a great load! I have tested it with my power supply and I was able to accurately pull currents up to 1 mA. I didn't do it for long though so I am not sure about the drift.
