总之,没有。
InfiniiVision-X示波器使用专有的采样率抖动算法来防止混叠(它将信号转换为宽带噪声,而不是某个错误频率的正弦波)。
除了4000X系列之外,您无法直接将其关闭。
但是,由于FFT需要等间隔采样,因此开启采样率抖动的FFT转向。
因此,启用FFT可以对信号进行别名,但是您无法直接控制采样率。
更改时间刻度会改变采样率,因此,如果您碰巧达到了您喜欢的采样率,那么您就可以了,否则,不会。

In a word, no.
The InfiniiVision-X scopes use a proprietary sampling rate dithering algorithm to prevent aliasing (it turns the signal into wideband noise, as opposed to a sine wave at some wrong frequency). You cannot directly turn it off except on the 4000X series. however, since FFTs require equally spaced samples, turning on FFT turns of the sampling rate dither. So turning on FFT allows you to alias the signal, but you do not have direct control over the sampling rate. Changing the time scale changes the sampling rate, so, if you happen to hit a sampling rate you like, then you are ok, otherwise, no.
