You can apply interference commands using an Interference Simulation File (*.itf) (double-click
Vehicle - Antenna_n - Options - Interference file) or dynamically through an Interactive Interference
dialog.
In most dialogs, you must enter the Action time in days and hh:mm:ss.
All GSS7725 commands persist until countermanded by another command in the same category.
Click on File - Save as to save the Interference Simulation File. Type a name for the file. The file
name you use appears in the Scenario tree next to Options - Interference file. By default, this file is
stored in the scenario folder.
