Measuring system of a hand-held oscilloscope
Under what circumstances should oscilloscope consider the sampling rate?
The bandwidth is dependent on the object under test. You want the minimum sampling interval (the inverse of the sampling rate) to capture the signal details you need, provided the bandwidth is satisfied. There are some empirical formulas about sampling rate in the industry, but basically they are all based on oscilloscope bandwidth, in practical application, it is best not to use oscilloscope to measure the same frequency signal. When selecting the type, the bandwidth of the oscilloscope should be more than 3 times that of the measured sinusoidal signal, and the sampling rate should be 4 to 5 times that of the bandwidth, which is actually 12 to 15 times that of the signal.For other waveforms, ensure that the sampling rate is sufficient to capture signal details. If you are using an oscilloscope, you can verify that the sampling rate is sufficient by stopping the waveform, amplifying the waveform, and if there is any change in the waveform (such as some amplitude), the sampling rate is insufficient, otherwise it will be ok. Point displays can also be used to analyze the adequacy of the sampling rate.
