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?

The ADALM1000 has two operating "modes" The usual default mode we call discontinuous where the output waveform (including DC) resets back to the beginning between each sweep and the output goes into the Hi-Z state when it is doing this reset. This mode does not require any form of triggering since the waveform starts the sweep at the same point each time.
The second mode is called continuous mode and as you might suspect the output is on continuously after the RUN button is clicked and stops and goes into the HI-Z state when the STOP button is clicked.
The two different mode are selected by using the Sync AWG check box in the AWG controls. If the box is checked the AWG outputs are synchronized with the sweeps that it is in discontinuous mode. When the box is not checked the outputs will be running in continuous mode.
I think that your issue will go away if you don't have the Sync AWG box checked. However it is very important to note that each time you change the DC value of the AWG output the output will turn off for a few mili-seconds while the AWG reconfigures to the new value. This is unavoidable. So using the AWG to power a circuit that "resets" if the power drops momentarily is not a good idea.
If you need to measure the current in such a circuit I would recommend using a conventional power supply and adding a series shunt resistor to monitor the current. The AD8210 current shunt monitor chip is a good option to convert the differential voltage across the shunt into a single ended (0-5V) signal that the ADALM1000 can measure.
