Hi,
During the RF test based on one of our CC2652P module, we found a problem
Hardware: RF-star RF-DG-52PA based on CC2652P
Test software: RFStudio 7
Test conditions: ZigBee protocol, TX power: 20 dBm, Center Frequency: 2480 MHz
When RBW is 1 MHz, there is a -30 dBm spurious emissions at the frequency of 2430 MHz. The reference photos are as follows:
We are applying for the certification, this problem is found. Hope you can help us to solve this problem and we can get the certification ASAP.
Thanks a lot.

Hi,
Did you check on our CC1352P-2 Launchpad?
Does the Spur level changes with the Tx Power Level? Just reduce the Tx power (for example 17dBm) and check the Spur level again.
I observed you are using older version of SmarRF Studio. Could you please update to the latest version and test again?
