Interference from BLE or not?



We designed a module for BLE communication based on the keyfob demo layout.
When the power of BLE is off, the noise variance of the power supply measured by the oscillometer is within normal range, as depicted in fig.1.
When the power of BLE is on and BLE is broadcasting, the noise variance of the power supply measured by the oscillometer is huge, as shown in fig.2.
Would you please figure out the possible reasons for us? Thanks a lot.
