Bode Plot (for DHO914S and DHO924S only)

Bode plot is a way of graphically displaying the frequency response of a system. In
the switch power supply and operational amplifier's circuit feedback network, the
Bode plot provides the curves displaying the variation of gain and phase with the
frequency for a loop analysis. Through the analysis on the system's gain and phase
margins, you can determine the stability of the system.
With the built-in signal generator module, the DHO914S and DHO924S series
generate the sweep signal of a specified frequency range and outputs to the switch
power supply circuit under test. Then, the oscilloscope draws a Bode plot displaying
the variation of phase and gain with different frequencies. Click or tap the function
navigation icon and select Bode Plots to enter the "Bode Plots" setting menu.
