I haven't worked with electronics in a long time, and now have the task of measuring the power consumption of a low-power device I'm writing firmware for...
When the device is drawing very little current, the DC power analyzer shows the current oscillating(?). So, my question is, is the average current of a reading with peaks of 100uA and -100uA, around 0A? or is it something else?
My confusion is because I didn't expect to have negative and positive values in my reading. Any help is much appreciated!
I'm using the Data Logger function of the Keysight N6705C DC power analyzer.
p.s: Attaching the reading from the analyzer. (Avg:8uA, Peaks: -256uA, 887uA). The spikes in the reading are not the issue since they are triggered by periodic tasks in the MCU. My concern is the min, max, average indicated in the reading.
