Ad justment part Ad just 06 [ Y-Delay PAL ]
Description
1. Receive a PAL colour bar signal. 2. Select <Adju st 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 dis tortion, 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.
Ad just 07
[ Y-Delay SECAM ] 1. Receive a SECAM colour bar s ignal. 2. Select <Adju st 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 eac h 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, s o for an equal delay of the luminance and chrominanc e signal the delay must be set at a value of 160nS. This means the adjustment must be set to the maximum value.
Ad just 08
[ Y-Delay NTSC ] 1. Receive a NT SC colour bar signal. 2. Select <Adju st 08> from SERVICE MENU. 3. Adjust Y-Delay NT SC 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 luminanc e and chrominance signal the delay must be s et at a value of 160nS. This means the adjustment must be set to the maximum value.
