The Master Signal Generator Sub-Panel is similar to the single device signal generator, and provides a Multi-Channel button, which opens a modal pop-up Master control sub-panel with Level and Enable controls for each device in the group. This feature allows the System Engineer to set a master signal generator level in the master panel then open the master sub-panel with controls for each individual to quickly run diagnostic listen tests on each device in the system. The pop-up will show up to eight device controls before creating a scroll bar. For details on the signal generator see help for Signal Generator
Each individual device control is independent from the others in the group.
The Enable button will turn Green when the signal generator for the attached device is activated.
