Connect the terminated Oscilloscope with 75
Ω
to the
Video Output Connector.
8
Adjust data with the ARROW keys so that the false
chrominance level becomes minimum as shown in Fig. 5-
13.
Note: The Data of 801F should be adjusted from FF, the first
minimum point of the false chrominance signal is
adjusting point.
