Dear Sir，
Please refer to the following explanation.
Real-time sampling: A/D conversion is performed on the waveform at equal time intervals and in the order of time, and stored. Real-time sampling is the most intuitive sampling method, which only needs to perform sampling at equal intervals in the order of time. Real-time sampling needs to meet: the sampling frequency needs to be greater than twice the highest frequency in the input signal, otherwise the information of the signal will not be restored.
Equivalent sampling: A sampling method that uses multiple sampling to reconstruct the waveform of the sampled signal according to a certain algorithm and then displays the waveform.
