2. Digital oscilloscope has storage function, which can pause and capture waveforms, while analog oscilloscope does not have this function;
3. Digital oscilloscope has communication function, which can communicate with computer and facilitate analysis;
4. The digital oscilloscope is sampling, the waveform displayed by the analog oscilloscope is real-time, and the low-frequency dynamic effect of the analog oscilloscope is obvious, which is not easy for the digital oscilloscope to observe;
5. Analog oscilloscope is expensive (limited by the bandwidth of amplifier and oscilloscope tube). Now the band height of digital oscilloscope is 40GHz, which analog oscilloscope can't do.
