From File

Create a signal from a File by selecting the From File button within the signals panel under the EMA3D tab in the ribbon.

A new window will appear. Browse to the signal source file and select it. Different file types are allowed (e.g., .dat, .txt, .prn., etc.), but users may need to change the file type in the bottom right of the window to find files other than .dat.

After adding a signal, the signal will appear in the Signals node within the Simulation Tree.

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.

Users can edit the signal time parameters 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.

To save the changes to the signal, close out of the signal window using the small x in the top right corner of the window.
