The duration of measurement depends on the configured maximum frequency. Depending on whether the envelope or raw values are to be measured, the following registers are used for configuration:

•MaxFrequencyEnvelope for envelope measurement

•MaxFrequencyRaw for raw value measurement

 

测量的持续时间取决于配置的最大频率。根据是否要测量包络值或原始值，使用以下寄存器进行配置：

•MaxFrequencyEnvelope 用于包络测量

•MaxFrequencyRaw 用于原始值测量
