您好，请问下图中90%setting、95%setting、99%setting分别是什么意思？
Shine：
这个表示chirp信号的的线性度(chirp linearity level)。
,
kelong zeng：
线性度是什么意思？能具体描述一下它的涵义吗？或者有关于它的文档？
,
Shine：
如您上面的图，斜线表示线性的。蓝色圈部分是非线性的。
,
kelong zeng：
那为什么会有三个不同的值？这三个值又是什么含义？
,
Shine：
请看一下下的培训视频。The table summarizes the optimized timings for a target settling level of 90%, 95%, or 99%. The settling level represents a chip linearity level during start of a chip, when the PLL is settling. The higher than linearity is, the more accurate the results will be.https://training.ti.com/mmwave-awr1x-power-optimization-options

请选用99% settlingAt the start of the chirp the internal circuits (like synthesizer, receiver chain filters etc.) will need some time to settle. The 90/95/99 % settling times indicate the time required for these circuits to settle within the mentioned percentage of the final value. For best performance its recommended to use the 99% settling time numbers.
