5. Performing a Frequency Domain Analysis

Complete the following steps to analyze the frequency response of the model.

1. In the Project View, right-click the Time Domain Analysis step and select Insert After»Control Design»Model Analysis»Frequency Domain Analysis from the shortcut menu to add a Frequency Domain Analysis step after the Time Domain Analysis step.
2. On the Configuration tab of the Step Setup tab, verify that Bode is the type of analysis in the Analysis Type pull-down menu.
3. Verify that Hz is the unit of frequency selected in the Frequency Unit pull-down menu.
4. Click the Frequency Analysis tab to view the analysis data of the model.
5. Click the Data View tab to view the Data View.
6. In the Project View, right-click the Magnitude0 output and select Rename from the shortcut menu. Change the name of this output to Bode Magnitude.
7. Rename the Phase0 output to Bode Phase.
8. Click the Bode Magnitude output of the Frequency Domain Analysis step and drag it from the Project View to the Data View to display the Bode Magnitude plot in the Data View. You can repeat this step with the Bode Phase output.

   Note  You can remove displays from the Data View by right-clicking the display that you want to remove and selecting Data View»Remove Display from the shortcut menu.

9. Right-click the Bode Magnitude graph and select X Scale»Logarithmic from the shortcut menu to change the X scale to logarithmic format. You can repeat this step with the Bode Phase graph.
