ADALM1000 as power monitor

Hello,

I'd like to use M1K as a power monitor for programmable devices as MCU.
I try to use it with Alice Desktop M1K, but the power provided is discontinuous, rebooting my device constantly.
I'd like to keep my device at constant tension (or decrasing, simulating a battery).
For now, I use only CH A, as SVMI mode, Term "open" (I don't know what this is about), Shape DC, min 5V, max 5V, Freq 1, phase 0°,100%.
I still get a square signal when I click run, enven if CH 1 is only connected to my scope.
Is it some documentation for how to reach this? Should I select some option?

Kind regards,

Hugo
