When the PPK calibrates and turns off the DUT, does the nRF52832 on the PPK disconnect from the External DUT lines? My DUT has a LOT of capacitance on it, and it takes several seconds to fully discharge the caps after power has been removed.
My question is: Does sending the RTT_COMMAND.RTT_COMD_DUT 0 (line 1143 in ppk.py) actually disconnect the External DUT lines from the ADC on the nRF52832? Will a voltage on the External DUT lines during PPK Calibration throw off the calibration?
