Setting root locus resolution

You can define the number of steps in the gain sweep, which in turn determines the point count resolution of the root locus gain.

To define the resolution for a root locus plot

1.    Choose Analyze > Root Locus Options.

2.    In Step Count, enter a value that indicates the step size for moving the gain. For a finer resolution, increase the step count. The default is 50.

Note: The larger the step count value, the longer it takes to compute the new root locus plot.

3.    Click OK, or press ENTER.

4.    Choose Analyze > Root Locus to generate a root locus plot with the specified step count.
