将示波器占空比、回测波形占空比、预设输出占空比三者对比验证。信号回测在

Compare and verify the duty cycle of the oscilloscope, the duty cycle of the back-tested waveform, and the preset output duty cycle. The signal backtest displays 30% in the middle of the first line on the LCD screen. At this time, the preset value is 30%, and the theoretically calculated value is 30%. It can be obtained that the three values ​​are consistent. The principle of 60% duty cycle is the same.

The oscillostor space ratio, the backtest waveform space ratio, and the preset output space ratio are compared and verified. Signal backtesting shows 30% in the middle of the first row on the LCD screen, at which point the preset value is 30% and the theoretical calculation value is 30%. Thus, the values of the three can be consistent. The 60% space-to-air ratio principle is consistent.

The duty cycle of oscilloscope, the duty cycle of back test waveform and the preset duty cycle of output are compared and verified. The signal back test is displayed 30% in the middle of the first line on the LCD screen. At this time, the preset value is 30% and the theoretical calculation value is 30%. The results show that the three values are consistent. The principle of 60% duty cycle is consistent.<br>
