Analog oscilloscope is mainly made of battery lead plate, electronic gun and other analog circuit technology; digital oscilloscope is mainly made of A/D and other digital circuit technology.
Different bandwidth: affected by the electronic offset speed, the bandwidth of the analog oscilloscope can only reach several hundred hertz, while the digital oscilloscope bandwidth has exceeded 100 GHz
Different function: digital oscilloscope can stable view continous periodic siganl and have automatic measurement, wave storage, wave analysis, multiple wave trigger, remote control and other functions.
Different stability: analog oscilloscope is made of analog components, indicators discrete and temperature excursion will have more serious impact; analog oscilloscope are relatively Larger in size; analog oscilloscope can capture real-time waveform, digital oscilloscope may cause segment wave loss when processing, but with the improvement of ADC speed and processing algorithm, the waveform capture rate has been able to meet the needs of use.
