我最近用LIS3DH加速度计进行了一些测试来测量机器的振动，我遇到了两件事。我正在使用加速度计以1.1Khz的采样率采样512点。我把它设置为正常模式，ODR = 1.3Khz，在512点我有时得到1或2个离群值与其余值非常不同，它似乎随机发生但我不确定来源（图片）附）。
我的第二个问题是关于加速度计的固有频率，因为我在数据表中找不到它。
问候。

I have been doing some tes
tings recently with the LIS3DH accelerometer to measure machine vibration, and I have come across 2 things. I am using the accelerometer to sample 512 points at a 1.1Khz sampling rate. I have it set a normal mode, with ODR =1.3Khz, out of the 512 points I sometimes get 1 or 2 outlier points with very different values from the rest, it seems to happen randomly but I am not sure of the source (picture attached).
My second question is about the accelerometer's natural frequency as i could not find it in the datasheet.
Regards.
