New miniature programmable DC power supply - FNIRSI DPS-150
Fungus:
Yeah, something like this is probably useless for Audio.

Here are the ripple measurements of my own PSU (12V), in case anyone is interested.
Above without load, below with 1.5W.
I will hardly need more power with this ps.
That's good enough for me.

Now with the load, change the aquire mode to average 8 and you'll get a more stable representation of the ripple of your ps, meaning a better visualization of the ups and downs of the stabilization.

These screenshots are taken in "Hi-res" mode.
This is also a type of averaging, but does not iron out as much as the “Average” mode.
I think that's fine. 250uVrms ripple at 12V is OK. I don't think I can (or want) improve on that.
Thanks.

High res won't "clean" the signal as much as average does and that's why average is nice to "make the signal thinner" by removing the less constant acquired points and keep the most stable ones. It's a way of loosing fat :-DD
