Name:
MaxFrequencyRaw01
名称:
MaxFrequencyRaw01
Registers for setting the maximum frequency of the channel. Reducing the maximum frequency allows the frequency resolution in the spectrum to be increased.
用于设置通道最大频率的寄存器。降低最大频率可以提高频率分辨率。

•Important information for configuring the maximum frequency
•The frequency range must be larger than the damage frequency but should otherwise be kept as small as possible in order to achieve a good resolution.
•When using broadband values (e.g. PeakRaw), only the largest peak value is returned during a measurement. Using a longer measurement time at a lower frequency can lead to the measured value being overlooked in some applications.
•The maximum frequency influences the size of the sampling rate and can be configured using register AnalogInput.
•配置最大频率的重要信息
•频率范围必须大于损坏频率，但应保持尽可能小的频率范围，以获得良好的分辨率。
•当使用宽频的值（例如PeakRaw）时，在测量过程中只返回最大的峰值。在某些应用中，在较低频率下使用较长的测量时间可能会导致测量值被忽略。
•最大频率（maximum frequency）会影响采样速率的大小，可以使用 AnalogInput 寄存器进行配置。
