I'm trying to do a power analysis of an embedded device with a PPK2 and nRF power profiler and i'm running into an issue where i'm losing samples on longer capture periods. It's set to a 10kHz sample rate but after running it for 2 minutes at this sasmple rate and exporting the csv file it's ~400k records long, when it should be ~1200k records long. Looking manually at the CSV files i can see that it's missing multiple milliseconds of samples very frequently
I first thought it was a RAM issue, so i make sure to close every extra program and only have the power profiler software running but the issue still presented. I also tried to downgrade to 3.5.5 and tried the latest beta 4.0.0 b6 but neither of those have fixed the issue. This is causing significant problems for my data analysis
