First, could you tell me what permanent relationship there is?

The sampling rate needs to meet the agricultural result fragrantly and sampling the law in theory, namely need to adopt 2 points at least in theory each cycle of the highest frequency signal of the measured signal, otherwise will cause the aliasing. But is still depending on a lot of other factors in fact, such as corrugate reconfiguration algorithm,etc., the Siglent series ondoscope adopts the advanced undulate reconfiguration algorithm, is equipped with the interpolation algorithm at the same time, reconstruct the waveform accurately. Sampling rate generally speaking is for the bandwidth one 4- 5 time can accurately recurrent waveform.

Second, how is the bandwidth in the ondoscope index understood?

The bandwidth is a basic index of the ondoscope, like definition of the amplifier bandwidth, it is so-called – 3dB clicks, namely, the input in the ondoscope adds the sine wave, it is called bandwidth for some of frequency of 70.7% o’clock of the actual range that the range decays. That is to say, the ondoscope which uses 100MHz bandwidth measures 1V, the sine wave of 100MHz, the Read more
