2.4 Reference and timing set up
2.4.1 Basic signal processing
The base station can be synchronized using HD tri-level or SD black burst references. Both
references can be adjusted to match the video output signals. This is an overview of the base
station output signal paths:
The default settings for the base station reference signals are:
•
The first reference is HD tri-level: the outputs are in time with the HD tri-level
synchronization.
•
The second reference is SD black burst: the outputs are in time with the SD black burst.
2.4.2 Adjustment procedure for HD timing
Tip
✎
When HD tri-level reference is used, the HD output is in sync with the HD tri-level reference. A
timing offset can be set with the
SYSTEM > TIMING > H PHASE COARSE and H PHASE FINE
items of the base station menu.
