Composite video output standard selection
This selection is made using rotary switch CO1150. Select the position corresponding to
the standard you require.
Equipment phase alignment with a digital installation
Equipment slaved to an external reference on «GENLOCK» input
The reference signal should be a black video signal with or without burst delivered by a
Broadcast generator and terminated with 75 Ohm load.
Horizontal phase alignment of the digital output signal
The horizontal phase of the digital output signal with respect to the external reference
signal is adjusted using the «
ΦH COARSE» and «ΦH FINE» thumbwheels. The range of
variation depends on the position of the lower switch of S1151.
S1151 up position (FINE):
• «
ΦH COARSE»: Adjustment in steps of 592 ns.
• «
ΦH FINE»: Adjustment in steps of 37 ns.
The range of variation of the digital output signal with respect to the reference signal is
approximately -6.4 µs + 2.7 µs.
S1151 down position (COARSE):
• «
ΦH COARSE»: Adjustment in steps of 1184 ns.
• «
ΦH FINE»: Adjustment in steps of 74 ns.
