In this configuration, the RMS value of the configured signal and channel in the frequency band is calculated. The value is calculated from the configured minimum frequency (FrequencyBandXXLowerFrequency) to the configured maximum frequency (FrequencyBandXXUpperFrequency). The minimum and maximum frequency can be entered here in increments of 0.25 Hz.

在该配置中，计算频带中从配置的最小频率 (FrequencyBandXXLowerFrequency) 到配置的最大频率 (FrequencyBandXXUpperFrequency)的信号信道的 RMS 值。最小和最大频率的步长为 0.25 Hz。

 

Any channel for any frequency band can be selected. The following signals can be selected for each channel:

可以选择任意通道的任意频带，可以为每个通道选择以下信号：

•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 。

 

The harmonic frequencies (integer multiples) of the window can also be included in the calculation. Here, the width of the window is simply retained and the mean frequency of the window is multiplied (by 1, 2, 3, etc.) until the maximum frequency of the configured signal and channel is reached.

窗口的谐波频率（整数倍）也可以包括在计算内。在这里，简单地保留窗口的宽度，并将窗口的平均频率相乘（乘以1、2、3等），直到达到配置信号和信道的最大频率。
