The Nyquist command computes the Nyquist plot of a system.



20-sim automatically generates a range of real and imaginary parts, based on the system dynamics. With the Plot Properties command (right mouse menu), you can change this horizon and recalculate the Nyquist diagram (click the Nyquist command again).
