Lightning Waveform

1. Within the signals panel under the EMA3D tab in the ribbon, select the Lightning waveform .

   

2. After adding a signal, the signal edit window will appear with a graph of the signal and various parameters that can be adjusted and waveforms selected. The signal can be edited immediately or at a later time by right clicking the signal name in the Simulation Tree and selecting edit in the pop-up menu. These parameters are described in the table at the end of this section. Additionally, the frequency spectrum of the signal can be inspected by clicking FFT in the top left of the window.

   

3. If you do not wish to edit the signal close out of the signal window using the small x in the signal tab beneath the model window .

4. The newly-created signal will be nested in the Simulation Tree under Signals within the Sources node.

   

5. To add the signal to a source, click and hold the signal within the Signals node in the Simulation Tree and then drag and drop it on the source (e.g., on the plane wave). The signal should then be nested beneath the corresponding source.
