资源简介:
动态储备反映了锁相放大器在被其他频率信号干扰下对待测信号的检测能力,定义为最大可容纳的噪声信号和满量程信号的比值。本数据集包含本项目设计的上位机软件对锁相放大器进行数据处理和分析得到的动态储备,上位机没有显示Overload,则说明动态储备≥140dB。 动态储备的定义是最大可容纳的噪声信号和满量程信号的比值。动态储备表示锁相放大 器对噪声容忍程度的大小,通常以 dB 表示。

Dynamic reserve reflects the detection capability for measured signals of a lock-in amplifier when interfered by signals of other frequencies, and is defined as the ratio of the maximum tolerable noise signal to the full-scale signal. This dataset contains dynamic reserve values obtained by processing and analyzing data from the lock-in amplifier using the host computer software developed in this project. If the host computer does not display "Overload", it indicates that the dynamic reserve is ≥140 dB. The definition of dynamic reserve is the ratio of the maximum tolerable noise signal to the full-scale signal. Dynamic reserve represents the noise tolerance of a lock-in amplifier, which is usually expressed in dB.
