LAUNCHXL-CC1312R1: About frequency shift.

Guru 10765 points
Part Number: LAUNCHXL-CC1312R1

Tool/software:

Hi team,

I'm using EVM of CC1312R1 and SMARTRF-STUDIO-7.
However, the phenomenon of different frequency variations is occurring.
I believe the frequency variations is constant whichever frequency band under the same environment because the internal clock is the reference.
Is the following difference a software problem or others ?

Tx frequency / setting : 429.2500[MHz]
Tx frequency / result : 429.249532 [MHz]
Variation:-1.09027373328393 [ppm]

Tx frequency / setting : 429.5000 [MHz]
Tx frequency / result : 429.499324 [MHz]
Variation:-1.573923166 [ppm]

Tx frequency / setting : 429.7375 [MHz]
Tx frequency / result : 429.735994[MHz]
Variation:-3.504464935 [ppm]

BR,
Kengo.
