2.1 MENU MANAGEMENT
A large number of options of the VEGA TV exciter can be easily and intuitively controlled through the human-
to-machine interface on the right side of the VEGA. It is composed by a graphic display and a clickable knob.
When the VEGA is switched on it initialise itself and query to all attached boards on bus the release number.
During this period the display shows the screen below.
After the initialisation the VEGA goes to the main menu which contains the deviation bars of the audio IF
carrier signals and the White and Synch bar of the video signal. The last bar on the bottom is the one of the
VCO which shows the position of the control voltage of the local oscillator.
