Here are some basic troubleshooting steps to help you fix issues you may encounter when using the Power Profiler Kit (PPK).
- PPK only measuring noise
-
Make sure you have prepared the nRF5 DK for current measurements by cutting the nRF current measurement solder bridge as described in:
- Measurements fluctuate when there should be a steady current draw
- Your Device Under Test (DUT) may have a power consumption that is close to a switching point causing rapid switching between the ranges and creating measurement errors/distorted plots. Try adjusting the switching points.
- Graph response is very slow
- Avoid using Universal Serial Bus (USB) hubs and docking stations. Also, if the trigger window is receiving a lot of updates, consider stopping this plot to have better throughput for the Average plot.
