Sender TPG (Test Pattern Generator)
The Sender TPG page allows test patterns to be applied to senders on a spigot-by-spigot basis.
The page displays a pane for each spigot in use, as shown above; captions can be defined, TPG
enabled or disabled and audio configured for each. However, when spigots are linked, only the
Master spigot can be configured; the Slave spigots inherit their configuration from the Master,
and have their controls disabled.
