Digital Oscilloscope DetailTips: How does an oscilloscope measure voltage?The oscilloscope can measure the voltage amplitude of various waveforms. It can measure both DC voltage and sinusoidal voltage as well as the amplitude of pulsed or non-sinusoidal voltages. What is more useful is that it can measure the voltage amplitude of each part of a pulse voltage waveform, such as the amount of impulse or the decrease in the top.
The comparative measurement method uses a known standard voltage waveform to compare with the measured voltage waveform to obtain the measured voltage value.
The measured voltage Vx is input to the oscilloscope's Y-axis channel, adjust the sensitivity of the Y axis, select the switch "V/div" and its fine adjustment knob, so that the screen displays a convenient measurement height Hx and make records, and “V/div” switch and the fine adjustment knob position remains unchanged. Remove the voltage under test, input a known adjustable standard voltage Vs into the Y-axis, and adjust the output amplitude of the standard voltage so that it shows the same amplitude as the measured voltage. At this point, the standard voltage output amplitude is equal to the measured voltage amplitude. The comparison method measures the voltage to avoid vertical system errors and errors, thereby improving the measurement accuracy.
