1. Set 05 CH.
2. Input the RGB 100% color bar signal into INPUTS 4
(G), 5 (B), and 6 (R).
3. Connect the oscilloscope to TP201 of the BD board.
4. Adjust the Y LEVEL data so that the G OUT signal
level A of TP201 satisfies the specification.

5. Connect the oscilloscope to TP501 of the BD board.
6. Adjust the PB LEVEL data so that the B OUT signal
level B of TP501 satisfies the specification.
Fig. 4-5.
7. Connect the oscilloscope to TP601 of the BD board.
8. Adjust the PR LEVEL data so that the R OUT signal
level C of TP601 satisfies the specification.
