How to measure the meshing frequency of planetary gears？

I used the planetary gear module as shown in the figure above，how to measure the meshing frequency of planetary gears？

Thank you for your answer

This block does not model the variation in speeds or power transmission due to the meshing effect of the teeth. You could calculate it analytically from the parameters in the block, and you could add that effect outside the block using friction and spring dampers.
