Is it correct to assume that frequencies indicated on the horizontal axis of a Bode plot acquired by an FRA (frequency response analyzer) are switching frequencies of the DC/DC converter?
- The horizontal axis of a Bode plot indicates the frequency of an applied signal. The Bode plot of an FRA represents the gain and phase of the voltage that passes through the circuit within the IC and has returned again to the analyzer when a sine wave set in the FRA is applied to the IC feedback section while sweeping through frequencies.
