In this configuration, the noise from a quadrant of the respective signal on the selected channel that is within the frequency band is calculated.

To do this, the configured maximum frequency (registers MaxFrequencyEnvelope and MaxFrequencyRaw) of the signal on the selected channel is divided by 4. This results in 4 quadrants. The configuration can then be used to select one of the 4 quadrants in which the noise should be determined.

 

在该配置中，计算来自频带内的所选通道上的各个信号的象限（四分频）的噪声。为此， 将所选通道上信号配置的最大频率 ( 寄存器MaxFrequencyEnvelope 和 MaxFrequencyRaw) 除以4，这会产生 4 个象限。然后，可以使用配置来选择应确定噪声的 4 个象限之一。

 

The following signals can be selected for each channel:

每个通道可以选择以下信号：

•Raw acceleration signal

加速度原始信号

•Raw velocity signal. Equal to 0 if the speed calculation is disabled.

原始速度信号，如果没有开启速度计算，则为 0 。

•Enveloped acceleration signal

加速度包络值

•Enveloped velocity signal. Equal to 0 if the speed calculation is disabled.

原始速度包络值，如果没有开启速度计算，则为 0 。

 

This configuration allows slippage to be effectively measured, for example. The higher the friction, the more noise that is created.

这种配置可以有效地测量滑移（slippage）。例如，摩擦力越大，产生的噪音就越大。
