LUMINANCESignalAdjust 06[ Y-Delay PAL ]
DELAYgenerator
1. Receive a PAL colour bar signal.
Adjustment
2. Select <Adjust 06> from SERVICE MENU.
3. Adjust Y-Delay PAL till the colour transients on the colour
bar of the pattern become as sharper and colours between
transients do not mix with each other as possible.
Note: If the SAW filter is one of the G1965M, J1951M, K2958M,
K2962M, G3957M, K6256K, K6259K or M1963M, there is
constant group delay distortion, so for an equal delay of
the luminance and chrominance signal the delay must be
set at a value of 160nS. This means the adjustment must
be set to the maximum value.
Adjust 07[ Y-Delay SECAM ]
1. Receive a SECAM colour bar signal.
2. Select <Adjust 07> from SERVICE MENU.
3. Adjust Y-Delay SECAM till the colour transients on the
colour bar of the pattern become as sharper and colours
between transients do not mix with each other as possible.
Note: If the SAW filter is one of the G1965M, K2958M,
K2962M, G3957M, K6256K or K6259K, there is constant
group delay distortion, so for an equal delay of the
luminance and chrominance signal the delay must be
set at a value of 160nS. This means the adjustment must
be set to the maximum value.
Adjust 08[ Y-Delay NTSC ]
1. Receive a NTSC colour bar signal.
2. Select <Adjust 08> from SERVICE MENU.
3. Adjust Y-Delay NTSC till the colour transients on the colour
bar of the pattern become as sharper and colours between
transients do not mix with each other as possible.
Note: If the SAW filter is M1963M, there is constant group delay
distortion, so for an equal delay of the luminance and
chrominance signal the delay must be set at a value of
160nS. This means the adjustment must be set to the
maximum value.
