Tool and Viewer Quick Start

Selecting Response Types

There are two methods for selecting response plots in the LTI Viewer:

• Selecting Plot Type from the right-click menus
• Opening the Plot Configurations window

Right Click Menu: Plot Type

If you have a plot open in the LTI Viewer, you can switch to any other response plot available by selecting Plot Type from the right click menu. This figure shows the right-click menu with Plot Type selected.

To change the response plot, select the new plot type from the Plot Type submenu. The LTI Viewer automatically displays the new response plot.

Plot Configurations Window

The Plot Type feature of the right-click menu works on existing plots, but you can also add plots to an LTI Viewer by using the Plot Configurations window. By default, the LTI Viewer opens with a closed-loop step response. To reconfigure an open viewer, select Plot Configuration under the Edit menu. This opens the Plot Configurations window.

Use the radio buttons to select the number of plots you want displayed in your LTI Viewer. For each plot, select a response type from the menus located on the right-hand side of the window.

It's possible to configure a single LTI Viewer to contain up to six response plots, as this figure shows.

Available response plots include: step, impulse, Bode (magnitude and phase, or magnitude only), Nyquist, Nichols, sigma, pole/zero maps, and I/O pole/zero maps.
