Comparative Experimental Study on the Simulated Oscilloscope and Digital Oscilloscope

This paper introduces the basic structure,working principle and the main advantages and disadvantages of simulated and digital oscilloscopes,and compares the waveform displaying ability of the two oscilloscopes. It also makes comparative studies between the two oscilloscopes in the four course experiments of single-stage amplifier,integral circuit,Signal and System of passive lowpass filter and television technology,and finds out their relative disadvantages of the two oscilloscopes when they are used in experiments. Finally,it provides some basic principles of choosing oscilloscope in university laboratory.
