The Vision software suite provides a monitor Simulator program used to practice and demonstrate using Vision. Although the simulator does not understand and respond to all Monitor SCPI commands, it does respond to the complete sub-set of commands that Vision uses. You can run multiple active simulators on the same PC with each simulator representing a different monitor in a database. Each simulator can be started with a command line reference to a control file to set the sweep parameters, GPS location, installed options and other parameters. For example, activate a set of simulators and coordinate their responses to simulate a moving target.
