PPK Current Measurement

Question

Hi, 
 Just wanted to confirm what the average current measured by the PPK represents. So for example if I have AVG in average window as 2.5mA, is that only the BLE (i.e. transmission) current or all of the MCU including any active peripherals? 
 The context is that I am getting significantly different values when using the PPK and OSC to measure the power on the nRF52 DK

 A: It will include all the current drawn by the nRF52832, including active peripherals. So if you are using e.g. PWM or SPI, this will increase the current consumption. 
 For more information see the PPK user guide . Also make sure that when you do measurement on the DK that the both power select and DUT is on "DK".
