Sampling system
To understand the oscilloscope's waveform acquisition system, you need to understand
the sampling principle and understand the relationship between sampling rate and
memory depth.
Sampling principle
According to the Nyquist sampling principle, in order to restore the analog signal with-
out distortion, the sampling frequency should be greater than twice the highest fre-
quency in the analog signal spectrum (Fs> 2Fmax). The higher the sampling rate, the
later the recovered waveform will be closer to the original signal, but the system re-
quirements will be higher, and the conversion circuit must have a faster conversion
speed.
