**Hello,**

**I am trying to extract the open-loop response (control to output bode plot) of a Buck PWM converter from PLECS Simulation Environment and I run into a 'problem' when displaying the waveforms.
The switching frequency of the converter is 200kHz.
The 'problem' is in the frequency range of the Inpulse Response Analysis.
I will attach a pdf file with some pictures for this purpose.**

**When the frequency range is larger then the simulation result for the high-frequency values is not so good or accurate.**

How can the display result of this 'problem be solved or improved'?

Also, I tried from the menu: Steady-State Options - to increase the value of some parameters (meaning to make: Number of init. cycles or Max. number of iterations bigger than 0 or 20) but without success in displaying a more accurate graph.

(I am using PLECS Standalone 4.1)

Thank you.
