AWR2944: Further question on chirp linearity

Tool/software:

Hi,

In below post, it mentioned that there will be <0.5Mhz of error for a very fast ramp when frequency chirping.

(+) AWR2944: What's the chirp linearity of AWR2944? - Sensors forum - Sensors - TI E2E support forums

Would you pls kindly advise if the 0.5Mhz refer to RMS or peak?

Thanks,

Chris
