Hi Everyone,

It's my learning process that I would like to get a bode plot of closed loop boost converter.
I injected a 10 ohm resistor on the top of the feedback resistor and applied a sweeping sine wave with my signal generator.
My siglent oscilloscope generates a bode plot. But, The signal is very noisy, is not continuous and bode plot is not useful.
I would like to hear your experience and advices how to improve the measurement.

Best regards
