2.4.3 Adjustment procedure for SD timing
The SD output signal can be delayed using the following procedure:
1.
Enter the base station menu in service mode:
MONITORING > MENU > MENU LEVEL > INST > SERVICEMODE > EXEC > YES
2.
After factory delivery there is a fixed minimum delay between HD and SD outputs:
SDTV > TIMING > COMP
3.
Set the SDTV timing to variable:
SDTV > TIMING > VAR
4.
Adjust the SD output delay using the following items:
SDTV > TIMING > SYNC SHIFT PIXELS and SHIFT LINES

Note
The adjustment must be carried out for each video mode. The last setting for each mode is
memorized.
The CVBS viewing output is a non-standard output and the SD output delay adjustment does
not apply to this output.
HD-trilevel sync does not contain 4-field (NTSC) or 8-field (PAL) sequence information and
therefore will be random. If this is required black burst reference should be used.
