If it is a digital oscilloscope, you can directly call out the required parameters from the measurement menu; The analog oscilloscope is about to read the scale, and the peak-to-peak voltage Vpp=V/div (vertical deflection factor) ×div (grid number occupied by the waveform in the vertical direction);
The effective value is equal to the peak-to-peak voltage divided by twice the root number 2; The rise time should be fine-tuned by vertical deflection factor and gain, so that the peak-to-peak value of the waveform falls within 0- 100, and the time for reading 10% to 90% is enough; The falling time is pronounced the same.

In order to improve the bandwidth of analog oscilloscope, it is necessary to popularize oscilloscope tube, vertical amplification and horizontal scanning. To improve the bandwidth of digital oscilloscope, we only need to improve the performance of front-end A/D converter, and there is no special requirement for oscilloscope and scanning circuit. In addition, digital oscilloscope tube can make full use of memory, storage and processing, as well as a variety of trigger and advanced trigger functions. In 1980s, digital oscilloscopes rose as a new force with many achievements, which may completely replace analog oscilloscopes. The analog oscilloscope did retreat from the foreground to the background.
