Analyze > Frequency Response lets you set the phase and gain margins before displaying the Bode phase and magnitude plots, like the ones shown below:

Both plots are relative to log frequency (in rad/s units). The magnitude units are log and the phase units are degrees.

Before you generate Bode magnitude and phase plots of a system, prepare the system for linearization.

**To generate Bode magnitude and
phase plots**

1.
Choose **Analyze** **>** **Frequency** **Range** to define the
range and resolution of the natural

2.
Choose **Analyze** **>** **Frequency** **Response** to set the
phase and gain margins and create the Bode phase and magnitude plots.
