Hi everyone,
I'm currently working on measuring the power consumption of the 9160DK board and following the guide: Getting started with current measurements on the nRF9160 - nRF9x - Hardware design, test and measuring - Nordic DevZone. My setup follows the SMU mode described in the guide, but instead of using the Power Profiler Kit, I’m utilizing the Joulescope JS110.
In the guide, the author mentions that the floor current of the UDP sample is 2.7µA, and my goal is to replicate this measurement. However, despite following the setup, my lowest recorded value is 3.6µA.
I would appreciate any insights on:
- Possible adjustments to my setup to further reduce the current.
- Explanations for why my measured value differs from the guide’s specifications.
Additional Information:
- SDK Version: v2.9.1
- Network Type: NB-IoT
- Input Voltage: 3.3V
Any suggestions or advice would be greatly appreciated!
