When the Power Profiler Kit II (PPK2) is used in Source Meter mode, the Device Under Test (DUT) is supplied power by the PPK2.
The voltage output to the DUT is adjusted with the Power Profiler app (see Using the Power Profiler app).
The following figure shows a typical measurement configuration using an nRF9160 DK v0.9.0 or later.
