PPK ampere mode high peaks

Hello, 
I ran the nrfconnect (ver 3.7.1) in Power Profiler (ver 3.1.3) in BLE advertising.

When I run the source mode on 3000V I get normal peaks  (20mA), however when I run the Ampere mode with the same voltage I see peaks of 45-50 mA.

On a different PC (same PS and cable , same nrf version and power profiler version) both Ampere mode and Source mode show the same values (as they should).

Thank you for your help.

  • Need to ask you for one more thing, could you click on the save/export and save as PPK and csv and share both.

  • ppkexports.zip the ppk and csv are in this zip , didnt let me upload separately
